Which imaging modality is commonly used to evaluate acute abdominal pain when ultrasound is inconclusive?

• A. CT abdomen/pelvis with contrast
• B. MRI abdomen/pelvis with contrast
• C. Ultrasound with Doppler
• D. Nuclear medicine scan

Answer: (B)

When ultrasound doesn’t reveal the cause of acute abdominal pain, you want imaging that provides detailed anatomy and tissue characterization without exposing the patient to radiation. MRI with contrast delivers superb soft-tissue contrast and, with gadolinium enhancement, can evaluate inflammatory or infectious processes, vascular perfusion, and delineate issues in solid organs, the biliary tree, and the pancreas. Diffusion-weighted imaging adds sensitivity for early edema, abscesses, or ischemia, helping distinguish different pathologies that may look similar on ultrasound. This makes MRI particularly advantageous in patients where radiation exposure should be avoided or where detailed soft-tissue information is essential, such as pregnant patients, children, or when repeat imaging might be needed and CT is undesirable. Practical considerations include longer exam times and availability, but when ultrasound is inconclusive, MRI with contrast often provides a more comprehensive and safer evaluation of the abdomen and pelvis.
