CT-Scan is useful in investigation of inflammatory problems, such as appendicitis, diverticulitis, Crohn's disease, and colitis. It is also indicated in the investigation of intestinal sub-obstructions to determine the cause (adhesions, obstructive neoplasm, regional lesions), specify the location, and assess signs of intestinal distress. CT-Scan is also useful in assessing the mesenteric ischemia. MRI has a limited role in the digestive investigation. It is primarily indicated in the assessment of the rectal neoplasm and local and regional extension. The digestive ultrasound is indicated for acute clinical problems, such as appendicitis, diverticulitis, and ileitis. It will prove very useful if positive, but remains a poor sensitive examination due to its technical limits related to the patient echogenicity, intestinal gas, and its operator-dependent aspect.
