We rely on such classification to guide our imaging recommendations—from open MRI scans to specialized TBI protocols—so that physicians and legal teams receive reliable, objective data. We explain what the CBI-M framework is, how it organizes brain injury categories, and why that structure leads to more targeted imaging choices. We provide a basic overview of TBI classification, cover the key elements of the CBI-M model, and describe the application of advanced MR imaging protocols (such as the SpinTech™ MRI TBI Protocol) to identify microhemorrhages and alterations of white matter in the brain. This document is intended for the general audience, e.g. patients and/or their family members evaluating their imaging options, and/or attorneys and law firms evaluating potential personal injury claims. We acknowledge the importance of clinical and/or subjective assessment and complementary imaging in the evaluation of TBI. Our commitment to clarity in every image and confidence in every decision flows from this classification-first mindset. Therefore, in line with our classification-first strategy, we will cover the basic elements of TBI classification and the place of CBI-M before describing the imaging options. Foundations of Traumatic Brain Injury Classification and the CBI-M Model Traditionally, traumatic brain injuries (TBIs) are classified as mild, moderate, or severe, often using the Glasgow Coma Scale (GCS) to measure severity. A patient scores mild TBI when their GCS score is 13 to 15. A patient scores moderate TBI when their GCS score is 9 to 12. A patient scores severe TBI when their GCS score is 8 or less. Duration of loss of consciousness and length of post-traumatic amnesia are added to sharpen the severity picture. Two patients with the same GCS score may show different symptoms, injury patterns, and recovery rates. The majority of TBIs are classified as mild. Often, conventional Computed Tomography (CT) scans or Magnetic Resonance Imaging (MRIs) do not show abnormalities, and patients are left to manage persistent post-concussive symptoms. Trying to fill that gap, the CBI-M model uses a multi-pillar assessment instead of a single assessment. The four pillars of the model are: Clinical History, Symptom Burden, Functional Assessment, and Imaging & Biomarkers. CBI-M Pillars vs. Traditional TBI Assessment Assessment Component CBI-M Framework Traditional Approach Clinical Advantage Clinical History Detailed accident history, prior concussions, and comorbidities Loss of consciousness duration Adds context beyond a single acute variable Symptom Burden Type, severity, and persistence of symptoms via validated checklists Post-traumatic amnesia duration Reflects daily patient experience, not just one parameter Functional Assessment Cognitive, balance, and oculomotor testing post-injury Glasgow Coma Scale Detects subtle functional deficits GCS cannot measure Imaging & Biomarkers Advanced MRI (quantitative DTI, volumetric analysis, microbleed detection) Conventional CT or MRI Reveals microstructural injury invisible to routine scans Functional assessment may uncover balance or processing-speed deficits that significantly affect daily life while routine imaging appears unchanged. The Imaging & Biomarkers pillar serves as the model’s objective anchor. Our centers utilize the SpinTech MRI TBI protocol, an advanced imaging sequence, which incorporates quantitative diffusion tensor imaging, and is able to detect microstructural changes that may be missed in standard sequences. As your trusted radiology partner, we provide this protocol throughout Arizona and Texas. Reports, reviewed by a fellowship-trained neuroradiologist, are provided within 24-48 hours. CBI-M Pillars versus traditional concussion assessment compared side by side Radiology, therefore, becomes the objective, quantifiable anchor for clinical and symptom burden and functional performance. For patients and their referring clinicians, we encourage imaging finding review with a qualified physician to aid in placement of the imaging findings in the context of symptoms and to assist with care planning. Imaging and Biomarker Integration: The Core Pillar of the CBI-M Framework The CBI-M framework is built upon objective, tissue-level evidence. Advanced imaging provides that layer. Unlike assessment tools that depend on patient self-report or bedside observation alone, imaging-derived biomarkers record injury directly from brain tissue. The Role of Advanced MRI and CT in CBI-M Standard emergency CT and conventional MRI protocols were not designed to capture the microstructural and microvascular injuries that define subacute and chronic traumatic brain injury. The CBI-M framework addresses this gap by integrating advanced MRI sequences, diffusion tensor imaging, or DTI, which measures the integrity of white-matter tracts by tracking water molecule movement, and susceptibility weighted imaging, which amplifies the magnetic signal of blood products to reveal microhemorrhages — along with CT when indicated. Our TBI-specific protocol exemplifies how dedicated imaging protocols strengthen the CBI-M evidence layer. The FDA-cleared equipment allows for quantitative DTI and volumetric analysis of the brain, as well as for the automated detection of microbleeds. Conventional MRI may miss up to 50 percent of cerebral microbleeds present in mild TBI cases, while this protocol is backed by more than 100 published research studies supporting its diagnostic sensitivity. Fellowship-trained, board-certified neuroradiologists interpret the studies and create structured reports across our network of centers in Arizona and Texas. How Quantitative Imaging Enhances Mild TBI Diagnosis The CBI-M framework alters the diagnostic equation to incorporate quantitative DTI (diffusion tensor imaging) metrics (i.e. fractional anisotropy and mean diffusivity) to describe the directional movement of water molecules along axonal pathways, as well as susceptibility-weighted imaging signal voids, which represent sites of parenchymal hemorrhage.

Personal Injury Medical Liens: Questions About the Agreement

azadvancedimaging.com / 20 September 2026

Before agreeing to imaging under a proposed medical lien, understand the written terms and seek advice for the relevant state. A lien should not be presented as automatic coverage or a guarantee of settlement. In this article Confirm costs before the appointment Review the specific obligations Using imaging records appropriately Arrange the examination before arriving Confirm costs before the appointment Request a written estimate for the ordered study and selected location. Ask whether the quoted amount includes the facility charge, radiologist interpretation, contrast and any additional services. For insurance, confirm network status, benefits and authorization requirements with the center and payer. An authorization or estimate does not establish that every charge will be paid. Ask what you may owe before agreeing to services. If a lien or letter of protection is proposed, request the actual written agreement and an explanation of payment obligations. Do not assume the arrangement makes imaging free or removes responsibility if a claim is delayed or unsuccessful. Review the specific obligations Ask who is responsible for the bill, when payment is due and what happens if the case is delayed, disputed or unsuccessful. Request a copy of every document before signing. Clarify whether the proposal is a lien, a letter of protection or another arrangement. Arizona and Texas requirements should not be described as interchangeable, and no universal state-law rule is asserted here. Using imaging records appropriately A radiology report describes medical findings and their limitations. It should be considered with the clinical history and other evidence; imaging alone does not establish accident causation, liability, damages or a settlement outcome. Confirm how the patient or authorized representative can request images and reports. Ask about the required authorization, intended recipient and delivery method rather than assuming a law firm has automatic portal access. Arrange the examination before arriving Contact scheduling to confirm the exact examination, location, imaging order and preparation. Ask whether a same-day or walk-in request can be accommodated; neither is a guaranteed appointment. An insurance referral and an imaging order are different requirements. Ask which documents and authorizations apply to your exam and bring the completed order, insurance information and photo ID as instructed. Tell the team about language, mobility, anxiety or transportation needs in advance. Confirm which assistance is available at the selected center and whether arrangements or eligibility checks are needed. Questions about imaging or scheduling? Call 844-641-2111 or find a location to contact your preferred imaging center.

Requesting and Sharing Medical Images: Privacy Questions to Ask

azadvancedimaging.com / 17 September 2026

Patients and authorized recipients should confirm how to request imaging records and how they will be delivered. A general description of security technology is not proof that a particular portal feature is implemented. In this article Request the records you need Confirm the real delivery workflow Share information carefully Request the records you need Ask how to request the radiology report and the actual images, which identity or authorization checks apply and which formats are available. HHS guidance describes patient access rights under HIPAA, subject to applicable conditions and exceptions. If another person or law firm needs records, confirm the appropriate release process and recipient details. Do not assume every third party has automatic access to the patient portal. Confirm the real delivery workflow Ask the center which portal, download, physical-copy or other delivery options it currently supports. Confirm how the intended recipient will gain access and whom to contact for assistance. This article does not claim that the center provides biometric login, law-firm API integration, watermarking, copy protection, specific encryption algorithms or automated audit-log features. Those require confirmation from the responsible team. Share information carefully Use the delivery instructions supplied by the center and verify the recipient. Ask before sending medical information to an unfamiliar link or third-party portal. For questions about privacy practices, identity checks, access records or fees, contact the center’s records or privacy team. This article is not a certification of its security controls or legal compliance. Questions about imaging or scheduling? Call 844-641-2111 or find a location to contact your preferred imaging center.

Radiology Report Turnaround: Planning Communication and Follow-Up

azadvancedimaging.com / 24 August 2026

Report delivery depends on the examination, interpretation and communication process. Appointment access and scan completion are separate from the time a final report reaches the ordering clinician. In this article Ask for a realistic estimate Distinguish urgent findings from routine reporting Reduce avoidable communication gaps Ask for a realistic estimate Confirm when the report is expected, how it will be delivered and whether prior studies or additional review may affect timing. Ask which contact can check a missing report. No universal ACR requirement that every routine report be completed within 24–48 hours is asserted here. A local service target must be confirmed rather than treated as a guarantee. Distinguish urgent findings from routine reporting If symptoms require emergency assessment, seek urgent care rather than waiting for an outpatient report. Ask the treating clinician how time-sensitive findings and follow-up will be handled. Patients should not have to infer a diagnosis from scheduling messages. Arrange a discussion with the treating clinician to interpret the report and decide next steps. Reduce avoidable communication gaps Provide accurate ordering-clinician details and ask how prior examinations should be transferred. Confirm the appropriate records-delivery method and intended recipient. For authorized legal records requests, ask about the release process separately; there is no promise of instant law-firm portal access or legally decisive findings. Questions about imaging or scheduling? Call 844-641-2111 or find a location to contact your preferred imaging center.

Musculoskeletal MRI in Phoenix: Questions About Exam Selection

azadvancedimaging.com / 15 August 2026

When comparing musculoskeletal imaging options, focus on the ordered examination, actual equipment and interpretation process. Unverified patient anecdotes or general claims of specialist expertise should not decide the choice. In this article Choose a scanner for the ordered exam Ask about the clinical report Arrange the examination before arriving Preparation and safety screening Plan for results and follow-up Choose a scanner for the ordered exam Open-sided MRI and a wider-bore enclosed scanner are different designs. Comfort, field strength and exam capability should be discussed separately; one design is not automatically the best choice for every clinical question. Confirm the scanner available at the specific center, the ordered protocol and patient-size limits before booking. A network-wide reference to open MRI does not mean every location has that equipment. Ask the ordering clinician and imaging team whether the proposed scanner can perform the study needed. Avoid choosing solely on a field-strength number, a general image-quality comparison or an unverified weight limit. Ask about the clinical report Confirm whether a particular specialist review is requested and available. Ask how prior studies can be provided and how the ordering clinician will receive the report. A testimonial cannot establish the expected diagnostic result or turnaround for another patient. Discuss the limitations of the proposed examination with the treating clinician. Arrange the examination before arriving Contact scheduling to confirm the exact examination, location, imaging order and preparation. Ask whether a same-day or walk-in request can be accommodated; neither is a guaranteed appointment. An insurance referral and an imaging order are different requirements. Ask which documents and authorizations apply to your exam and bring the completed order, insurance information and photo ID as instructed. Tell the team about language, mobility, anxiety or transportation needs in advance. Confirm which assistance is available at the selected center and whether arrangements or eligibility checks are needed. Preparation and safety screening Follow the instructions for the exact examination rather than assuming every scan has the same preparation. Tell the team about implants, medical devices, possible pregnancy, relevant medical history and any contrast-related concerns. For MRI, complete the safety screening and follow instructions about metal, clothing and hearing protection. MRI uses no ionizing radiation, but that does not make every device, patient or examination suitable for every scanner. If you have claustrophobia, discuss scanner options and comfort measures before booking. Medication or sedation requires an individualized plan; confirm whether it is available and follow the prescribing clinician’s preparation, recovery and transport instructions. Plan for results and follow-up Ask when the report is expected, how it will reach the ordering clinician and whom to contact if it has not arrived. Routine report timing depends on the study and review process; no fixed delivery deadline is promised here. The treating clinician interprets the report alongside symptoms, examination findings and prior studies. Imaging does not by itself determine treatment, the cause of an injury or a legal outcome. Request a clinical follow-up plan. Questions about imaging or scheduling? Call 844-641-2111 or find a location to contact your preferred imaging center.

Workers’ Compensation Imaging Authorization: Questions to Confirm

azadvancedimaging.com / 12 August 2026

Workers’ compensation imaging can involve an ordering clinician, employer, claims administrator and imaging center. Confirm their roles and requirements for the specific claim and jurisdiction. In this article Identify the responsible contacts Separate authorization, scheduling and results Arrange the examination before arriving Confirm costs before the appointment Plan for results and follow-up Identify the responsible contacts Have the claim number, adjuster or administrator details and ordering clinician’s information available. Ask which provider network, referral and authorization rules apply before arranging the exam. Decision timing varies by payer, request and applicable rules. No universal three-to-five or three-to-ten-business-day approval window is promised here. Separate authorization, scheduling and results Ask who will submit clinical documentation and track the request. If a denial occurs, request the reason and the payer’s review steps; an additional discussion does not guarantee approval. An approval does not by itself establish an open appointment, the patient’s full benefits or a report deadline. Confirm each step separately. Arrange the examination before arriving Contact scheduling to confirm the exact examination, location, imaging order and preparation.

Radiology Prior Authorization: A Guide for Patients and Providers

azadvancedimaging.com / 9 August 2026

Prior authorization is a payer review process that may apply before an imaging service. The applicable requirements depend on the plan, examination and circumstances; authorization is separate from the clinical order and appointment. In this article Confirm responsibilities early 2026 CMS requirements and their scope Prepare a complete request Plan for results and follow-up Confirm responsibilities early Ask the ordering clinician, imaging center and payer who will submit the request, which documentation is needed and how status will be communicated. Do not assume the imaging center manages every part of the process. If a request is denied, ask the payer for the reason and available review or appeal steps. A peer-to-peer discussion, when offered, follows that payer’s process and does not guarantee approval. 2026 CMS requirements and their scope The CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F) introduced process requirements generally beginning January 1, 2026. Its decision-timeframe requirements cover applicable Medicare Advantage, Medicaid and Children’s Health Insurance Program (CHIP) payers for medical items and services, excluding drugs. According to CMS’s prior authorization guidance, covered payers must decide requests as quickly as the patient’s condition requires, generally within seven calendar days for standard requests or 72 hours for expedited requests after receipt. Program-specific rules permit certain extensions. These timeframes do not apply to Qualified Health Plan issuers on the Federally-facilitated Exchanges under this rule and should not be assumed to govern every commercial plan or workers’ compensation request. The rule’s application programming interface (API) requirements generally have compliance dates beginning January 1, 2027, with dates varying by payer type. Prior authorization decision deadlines are separate from appointment availability and radiology report turnaround. Confirm the applicable plan’s requirements and request status with the payer and ordering clinician; the rule does not guarantee an approved scan or immediate imaging access. Prepare a complete request Confirm the ordered study, clinical reason, relevant notes and any requested prior imaging. Requirements differ; prior physical therapy or another conservative treatment should not be presented as a prerequisite for every injury or exam. A payer decision deadline is not a promise of immediate scheduling or a report-delivery deadline. Ask separately about appointment availability, preparation, benefits and expected charges. Plan for results and follow-up Ask when the report is expected, how it will reach the ordering clinician and whom to contact if it has not arrived. Routine report timing depends on the study and review process; no fixed delivery deadline is promised here. The treating clinician interprets the report alongside symptoms, examination findings and prior studies. Imaging does not by itself determine treatment, the cause of an injury or a legal outcome.

SpinTech STAGE and TBI MRI: Regulatory Scope and Limitations

azadvancedimaging.com / 6 August 2026

A software clearance and an MRI service protocol are not the same thing. Regulatory claims should identify the actual product and intended use rather than imply approval of an entire TBI diagnosis pathway. In this article Read the product record precisely What imaging can and cannot establish Discuss the local examination Plan for results and follow-up Read the product record precisely FDA record K210843 identifies STAGE from Spintech, Inc., and a 510(k) substantially equivalent decision dated June 29, 2021. It does not establish blanket FDA approval of all DTI, volumetry, QSM or locally branded TBI protocols. Ask the center to confirm the installed product, version and intended use. This article does not assert exclusive FDA-cleared technology, a fixed microbleed-detection percentage or a universally faster scan. What imaging can and cannot establish A concussion assessment starts with a healthcare provider’s clinical evaluation. Brain imaging is not routinely needed to identify every mild TBI or concussion; the clinician selects tests when they address a specific concern. CT and MRI can help evaluate some structural injuries, but they cannot detect every TBI. A normal scan does not by itself exclude a concussion, and an abnormality must be interpreted in clinical context. Advanced methods such as DTI, SWI and quantitative analysis have different uses and limitations. Do not treat a technique, software result or marketing protocol as a stand-alone diagnosis or a guarantee that subtle injury will be found. Discuss the local examination Confirm the ordered sequences, scanner compatibility, location and preparation. An educational description of SWI, DTI or QSM does not establish that every center provides those techniques. Plan for results and follow-up Ask when the report is expected, how it will reach the ordering clinician and whom to contact if it has not arrived. Routine report timing depends on the study and review process; no fixed delivery deadline is promised here. The treating clinician interprets the report alongside symptoms, examination findings and prior studies. Imaging does not by itself determine treatment, the cause of an injury or a legal outcome. Request a clinical follow-up plan. Questions about imaging or scheduling? Call 844-641-2111 or find a location to contact your preferred imaging center.
