Which specialized radiographic view best visualizes the bony borders of the carpal tunnel?
Answer: Carpal tunnel (tangential) view
The carpal tunnel view is taken with the wrist in dorsiflexion and the beam directed along the tunnel, profiling the hook of hamate and pisiform.
Which radiographic finding on an AP knee view is most consistent with osteoarthritis?
Answer: Joint space narrowing
Osteoarthritis on radiograph classically shows joint space narrowing along with osteophytes, subchondral sclerosis, and subchondral cysts.
The Ottawa Ankle Rules recommend radiographs based on which clinical findings?
Answer: Bone tenderness at specific sites and inability to weight bear
Ottawa Ankle Rules require X-rays when there is bone tenderness at the posterior fibula or tibia malleoli, or inability to bear weight immediately after injury and in the ED.
Which MRI sequence is most sensitive for detecting soft tissue edema and ligament tears in the extremities?
Answer: T2-weighted or STIR
T2-weighted and STIR sequences display fluid as bright (hyperintense) signal, making them ideal for detecting edema, ligament tears, and joint effusions.
A Hill-Sachs lesion of the posterolateral humeral head is best visualized on which shoulder X-ray view?
Answer: Internal rotation AP
The Hill-Sachs compression fracture is best seen on the AP shoulder view with the arm in internal rotation, which brings the posterolateral head into profile.
Which imaging modality is preferred for detecting stress fractures not yet visible on plain radiographs?
Answer: MRI
MRI is the gold standard for early stress fracture detection, revealing bone marrow edema before cortical changes appear on radiographs.
