When non-contrast vs contrast?

Non-contrast: urolithiasis, suspected acute hemorrhage, stone follow-up. IV contrast: appendicitis, diverticulitis, mesenteric ischemia, staging, abscess. Portal venous phase is the standard for abdomen.

When prefer MRI over CT?

Focal liver lesion characterization (especially cirrhosis / LI-RADS), biliary tree (MRCP), deep endometriosis, complex pelvic lesion and pregnant patients.

Appendicitis — sensitivity?

Contrast-enhanced CT has > 95% sensitivity and > 95% specificity for acute appendicitis in adults — superior to US and clinical evaluation alone.

When to use

Abdominal CT is the method of choice for acute abdominal pain (appendicitis, diverticulitis, ischemia, perforation), complicated pancreatitis, urolithiasis (non-contrast), oncologic staging and stable abdominal trauma. For focal liver lesion characterization, hepatobiliary MRI is generally superior.

What to evaluate

Solid viscera: size, attenuation, focal lesions, enhancement.
Bowel: caliber, wall thickness, content, inflammatory signs.
Urinary tract: stones, hydronephrosis, filling defects.
Vessels: aorta, mesenteric, portal — caliber, thrombosis, occlusions.
Lymph nodes, ascites, free air, collections.
