Final answer:
A CT exam that involves delivering a contrast agent into the small bowel through a nasogastric tube is known as CT Enterography or CT Enteroclysis, which is used for high-resolution imaging of the small intestine.
Step-by-step explanation:
The specialized CT exam that involves the administration of an enteral contrast agent directly into the small bowel via a nasogastric tube is known as a Computed Tomography (CT) Enterography or CT Enteroclysis. In this procedure, a tube is advanced through the patient's nose, down the throat, and into the stomach until it reaches the small intestine. At this point, a contrast agent, typically barium sulfate, is introduced to coat the lining of the gastrointestinal (GI) tract. CT Enterography provides a high-resolution, cross-sectional view of the small intestine, which is useful for identifying abnormalities such as inflammation, tumors, and other disorders of the small bowel.
Computed tomography (CT) is a medical imaging technique that creates detailed images of internal structures using X-rays and computer processing. The images are generated from multiple X-ray measurements taken from different angles, resulting in cross-sectional views that can reveal minute details about body structures with a high level of clarity. This noninvasive technique allows for quality imaging of the small intestine without the need for invasive surgery, providing valuable diagnostic information.
