Which imaging modality is not the preferred approach for stable patients with suspected intra-abdominal injury after resuscitation?

• A. CT scan of the abdomen and pelvis
• B. Focused ultrasound assessment with sonography in trauma (FAST)
• C. MRI of the abdomen
• D. Plain X-ray abdomen

Answer: (C)

In hemodynamically stable patients after resuscitation, the aim is to quickly and accurately characterize abdominal injuries to guide management. A CT scan of the abdomen and pelvis with IV contrast provides the fastest, most comprehensive view of solid organs, vascular injury, and hollow viscus damage, making it the preferred imaging choice in this scenario. FAST is useful as a rapid bedside check for fluid and is particularly helpful if the patient is unstable or as an initial triage step, but it doesn’t give the full detail a CT can in a stable patient. Plain abdominal X-ray has limited sensitivity for many intra-abdominal injuries and isn’t reliable enough to base management on. MRI, while excellent for certain soft-tissue evaluations, is not practical in acute trauma due to longer scan times, limited availability, and the need to move or reposition the patient, which makes CT the better option in this setting.
