Answer

A newer CT technique (called CT enterography) is a contrast CT technique in which larger than normal amounts of oral contrast are ingested by the patient. This technique, which requires a skilled radiologist, allows for better visualization of the small bowel mucosa and is considered by some to be superior to the small bowel x-ray series because of its ability to identify extraintestinal lesions; for diagnosing intestinal disease, it compares favorably with capsule enterography, ileocolonoscopy, and small bowel follow-through x-ray. In situations where repeated studies are needed, MR enterography may be considered in order to avoid excess radiation exposure. [64, 65, 66]
