MRI Image Review/Clinical Correlation
The MRI Report Is Not the MRI
Independent image review may identify clinically significant spinal findings that warrant further clinical-imaging correlation beyond the written radiology report.”
As a spine MRI review expert witness, Dr. Peter Zilahy evaluates the actual MRI images in conjunction with the patient’s clinical presentation, examination findings, and injury mechanism. A focused review may identify clinically significant spinal pathology that was not fully characterized or correlated in the written radiology report.
In complex spine injury cases, the actual MRI images are evaluated in conjunction with the clinical history, clinical findings, prior imaging when available, and biomechanical evidence to determine what the totality of the evidence supports regarding injury, causation, and clinical significance.

In complex spine injury cases, the actual MRI images are evaluated in conjunction with the clinical history, clinical findings, prior imaging when available, and biomechanical evidence to determine what the totality of the evidence supports regarding injury, causation, and clinical significance.
Why the Actual MRI Images Matter
A radiology report is a written interpretation and summary of an imaging study; it is not a substitute for reviewing the complete image set when clinical correlation is required.
In complex spine injury cases, the important question is not simply whether an MRI is “positive” or “negative,” but whether the imaging findings anatomically and clinically correlate with the patient’s symptoms, objective examination findings, injury mechanism, and clinical course.
The purpose of independent MRI review is not simply to identify abnormalities, but to evaluate whether clinically significant pathology has been fully characterized and appropriately correlated with the patient’s history, examination findings, injury mechanism, and clinical course.
Representative MRI Reviews
Representative Findings From MRI Review
The following de-identified cases illustrate how review of the actual MRI images, integrated with the clinical record, objective examination findings, and injury biomechanics, can clarify pathology relevant to diagnosis, causation, and clinical significance.
Previously Unreported Disc Herniation
The original MRI report described a disc bulge. Independent review of the actual MRI images demonstrated a clinically significant disc herniation that had not been characterized in the original interpretation. Following re-review of the images, the interpreting radiologist authored an addendum documenting the herniation. The imaging findings were then correlated with the patient’s clinical history, objective examination findings, clinical presentation, and documented injury mechanism, providing additional evidence relevant to diagnosis and causation.
Acute Traumatic Endplate Fracture
Independent review of the MRI images identified findings consistent with an acute traumatic endplate fracture. Sequential MRI demonstrated evolution from Modic type 1 marrow signal changes to Modic type 2 changes at the involved endplate. This temporal imaging progression, considered together with the clinical history, examination findings, and injury mechanism, supported the opinion that the endplate injury was traumatic rather than simply a longstanding degenerative finding.
Partial Interspinous Ligament Injury
The original MRI report did not identify ligamentous injury. Independent review of the actual MRI images demonstrated increased T2 signal and edema within the L3–L4 and L4–L5 interspinous ligaments, findings consistent with partial interspinous ligament injury. The interpreting radiologist subsequently re-reviewed the study and issued an addendum documenting the ligamentous abnormality. This provided additional objective imaging evidence supporting the presence of post-traumatic interspinous ligament injury and its correlation with the clinical findings and injury mechanism.
Forensic Significance
These representative cases illustrate how independent review of the actual MRI images clarified clinically significant pathology and identified objective imaging findings relevant to diagnosis, clinical correlation, injury mechanism, and causation.
Clinical-Imaging Correlation
The Most Important Finding Is Often the Relationship Between the Evidence
Clinical Presentation
Symptoms, neurologic findings, functional loss, and examination findings establish the clinical pattern that requires explanation.
MRI Image Findings
The actual images are evaluated for disc injury, neural compromise, edema, ligament injury, endplate injury, and other structural abnormalities.
Clinical-Imaging Correlation
Imaging findings are anatomically correlated with the clinical presentation, clinical history, injury mechanism, and course of care to evaluate their significance.
Lurie et al. compared lumbar MRI interpretations by clinical spine specialists and radiologists in patients with symptomatic disc herniation. Agreement regarding the presence and vertebral level of herniation was excellent (93.4%). However, in 42.2% of cases in which the vertebral level was agreed upon, the radiology report did not provide sufficient detail to classify disc-herniation morphology as protrusion, extrusion, or sequestration. Among the 214 cases in which morphology was specifically described, clinician-radiologist agreement regarding morphology was only fair (κ = 0.24).
These findings illustrate why review of the actual MRI images, use of standardized terminology, and clinical-imaging correlation can be important in complex spine injury cases.
Lurie et al. — PubMed
A written radiology report is an important component of the diagnostic record; however, when the patient’s symptoms, examination findings, injury mechanism, or clinical course are not fully explained by the reported findings, review of the actual MRI images may provide important additional information.
The purpose of a focused MRI review is not to replace the radiologist. It is to evaluate whether the actual images contain clinically significant findings that require closer clinical correlation.
What the Review Examines
What the MRI Review Examines
The review is directed toward imaging findings relevant to diagnosis, clinical-imaging correlation, injury causation, permanency, and the overall understanding of the case.
01.
Disc Pathology
Evaluation of disc protrusions, extrusions, annular disruption, endplate changes, and other findings requiring correlation with the injury mechanism and clinical presentation.
02.
Neural Pathology
Evaluation of nerve-root involvement, foraminal compromise, spinal canal findings, and other abnormalities that may correlate with radicular or neurologic symptoms.
03.
Trauma-Related Findings
Evaluation for edema, acute structural change, soft-tissue injury, and other imaging findings potentially relevant to the temporal relationship and injury mechanism.
04.
Ligament Injury & Abnormal Motion
Identification of imaging findings relevant to ligament injury and correlation with abnormal intersegmental motion when dynamic imaging is available and clinically appropriate
05.
Underreported or Incompletely Characterized Findings
Attention to pathology that may have been mentioned without adequate characterization, minimized as incidental, or omitted from the original report.
06.
Demonstrative Imaging
Selection and annotation of key images to help attorneys, treating providers, and jurors understand the location, character, and clinical significance of relevant clinical pathology.
How the Review Works
01.
Review the Actual Images
The complete MRI study is reviewed rather than relying solely on the written radiology report.
02.
Compare the Radiology Report
The reported findings are compared with the findings identified on independent review of the actual images.
03.
Correlate the Clinical Evidence
Symptoms, objective clinical findings, injury mechanism, relevant clinical history, and clinical course are correlated with the imaging findings.
04.
Identify the Key Findings
The most clinically significant imaging findings are identified, characterized, and organized for clinical and forensic analysis.
05.
Explain the Significance
Relevant findings are translated into clear language and demonstrative images for attorneys, treating providers, and jurors.
When a Focused MRI Review May Be Particularly Valuable
- The written radiology report does not adequately explain the patient’s symptoms
- Significant clinical findings appear inconsistent with findings characterized as “mild” or “degenerative” in the written report
- Causation is disputed
- Pre-existing degeneration complicates the assessment of traumatic injury
- Radicular symptoms are not adequately explained by the written report
- The attorney needs to understand the clinical and imaging strengths and limitations of the evidence
IImage #4 is an axial (looking down) T2 GRE image of the C6–C7 disc. Image #5 demonstrates the central disc protrusion outlined by the RED LINE, extending from the annular fissure into the thecal sac, defined by the BLUE LINE, with resulting deformation of the spinal cord as delineated by the AMBER LINE.
Demonstrative Evidence
Turning Complex MRI Findings Into Clear Visual Evidence
A key MRI finding may be apparent on the images but difficult for an attorney or juror to interpret without explanation. Selected images can be enlarged, labeled, and organized to demonstrate the location, extent, and clinical significance of the imaging findings.
- The location of the pathology
- The involved spinal level
- The relationship to a nerve root or other structure
- Comparison with adjacent or normal anatomy
- The relationship between the imaging findings, objective examination findings, and the patient’s symptoms
Effective demonstrative evidence should clarify the imaging and clinical evidence without exaggerating it.
Differentiation
From Imaging Abnormality to Clinical Significance
Identifying an MRI abnormality is only the beginning. The more important forensic questions are whether the finding is clinically relevant, anatomically consistent with the patient’s presentation, temporally related to the event, and supported by the broader evidence.
Does the finding explain the patient’s symptoms and objective clinical findings?
Is it compatible with the injury mechanism?
Was the same region symptomatic or functionally impaired before the event?
Does the imaging support a structural injury, and is there objective evidence of a lasting functional consequence?
Can the finding be explained clearly and accurately to a jury?

MRI findings are correlated with the patient’s clinical history, objective examination findings, clinical course, injury mechanism, and functional presentation.
Does the MRI Report Tell the Complete Story?
When the written report does not fully explain the patient’s clinical presentation, review of the actual MRI images can provide important additional information for clinical correlation and causation analysis.
