In suspected solid organ injury, which imaging modality is preferred when the patient is hemodynamically stable?

• A. Ultrasound
• B. X-ray
• C. CT scan
• D. MRI

Answer: (C)

In hemodynamically stable patients with suspected solid organ injury, contrast-enhanced CT of the abdomen and pelvis is preferred because it quickly provides detailed visualization of liver, spleen, and kidney injuries, helps grade their severity, and detects active bleeding or vascular injury. This information is crucial for deciding whether nonoperative management is safe or if surgical intervention is needed. Ultrasound (FAST) is excellent for rapid assessment of free fluid and is especially useful if the patient is unstable, but it misses smaller or retroperitoneal injuries and cannot reliably grade organ damage. X-ray has limited value for intra-abdominal injuries, and MRI, while very informative, is impractical in the acute setting due to longer scan times and the need for stable conditions.
