Which imaging modality is most appropriate as the preferred evaluation for a stable patient after resuscitation with suspected intra-abdominal injury?

• A. Ultrasound FAST
• B. CT scan of the abdomen and pelvis
• C. MRI abdomen
• D. Plain X-ray abdomen

Answer: (B)

In a stable patient after resuscitation with suspected intra-abdominal injury, you want a test that gives a complete, rapid, and highly accurate view of the abdomen to guide management. A CT scan of the abdomen and pelvis with IV contrast provides that level of detail: it detects solid organ injuries, bowel and mesenteric trauma, retroperitoneal injuries, and active bleeding through contrast extravasation, and it also helps stage injuries for deciding between operative and nonoperative care. Its multiplanar reconstructions and wide availability make it the most informative single study in this scenario, and it generally reduces unnecessary surgeries. Ultrasound FAST is valuable for rapidly assessing unstable patients because it quickly checks for free intraperitoneal fluid, but it isn’t as comprehensive for a stable patient and can miss retroperitoneal or small bowel injuries. MRI isn’t practical in the acute trauma setting due to longer scan times and availability, and plain X-ray abdomen lacks sensitivity for most intra-abdominal injuries.
