Computed Tomography (CT) Abdominal Bowel Obstruction Evaluation of Small Intestine and Mesenteric Tissue
This targeted abdominal CT exam uses low-dose X-ray technology to capture high-resolution cross-sectional images of your small intestine, large intestine, bowel loops, and surrounding mesenteric tissue to assess for structural abnormalities causing bowel obstruction. It is specifically designed to evaluate the gastrointestinal tract for partial or complete blockages, bowel wall thickening, mesenteric inflammation, or other pathological changes that may be triggering symptoms like severe abdominal pain, persistent vomiting, and inability to pass gas or stool. No intravenous or oral contrast material is required for this specific protocol, minimizing preparation time and risk of adverse reactions for patients.
This low-dose radiation-based abdominal CT scan images your small intestine, bowel, and mesenteric tissue to diagnose the cause and severity of suspected bowel obstruction without the need for contrast material.
