Objective IME assessment of causation of radiological findings - Dr Behnam (Ben) Mohrarami

1 / 5

Which imaging modality has limited value in trauma cases because it often leads to further CT imaging regardless of findings?

A. MRI

B. Ultrasound

C. X-ray

D. Bone scan

2 / 5

When imaging is performed 12 months after an injury without prior comparison studies, determining causation is difficult primarily because:

A. CT cannot detect degenerative disease

B. MRI cannot show disc pathology

C. Degenerative changes may have developed over time

D. Ultrasound becomes more sensitive

3 / 5

Disc desiccation identified within weeks of trauma is most accurately interpreted as:

A. Strong evidence of acute disc injury

B. A rapid post-traumatic degenerative change

C. Unrelated to recent trauma because it is a slow degenerative process

D. Diagnostic of annular fissure

4 / 5

Bone marrow oedema on MRI:

A. Always indicates an acute fracture

B. Is specific to traumatic injury

C. May persist for many months and occur in non-traumatic conditions

D. Only occurs in degenerative disease

5 / 5

Why is ultrasound often less reliable in medicolegal assessments?

A. It cannot visualise ligaments

B. It is highly operator dependent

C. It exposes patients to excessive radiation

D. It cannot detect fluid collections
