GI TRACT AND PERITONEUM: Normal morphology of the stomach and duodenum. Normal caliber small and large bowel. Normal appendix. No ascites. VASCULATURE: Portal, splenic, and superior mesenteric veins are patent. Visceral arteries are patent. No abdominal aortic aneurysm. LYMPH NODES: No adenopathy.

2024年6月2日 · CT is excellent for small bowel pathology and is commonly performed to look for obstruction or inflammation. Small bowel obstruction will show dilated (i.e., stretched-out), fluid-filled loops of small bowel that become small in size after the point of obstruction.

2024年11月16日 · Small bowel follow-through is a fluoroscopic technique designed to obtain high-resolution images of the small bowel. The motility of the small bowel can also be grossly evaluated. The small bowel follow-through can be useful for the evaluation of: Limitations of the small bowel follow-through include:

2023年2月3日 · The small bowel (or small intestine) is the section of bowel between the stomach and the colon. It has distinctive mucosal folds, valvulae conniventes, and is made up of three functional units: duodenum. jejunum. ileum

2014年5月21日 · The normal bowel will enhance bright especially if the scan is in the late arterial phase, i.e. 35-40 seconds post injection. If the bowel wall is not thickened, this is normal enhancement.

2020年3月4日 · Small bowel. The normal small bowel is easily visualized by US and is recognized by continuous and vivid peristalsis, even if the lumen is empty. Note multiple small round echolucencies with a hyperechoic border within the bright submucosa. These represent normal 0.4 – 0.5 mm vessels.

2024年6月2日 · In typical small bowel obstruction caused by adhesive disease there are three key imaging findings to help make the diagnosis: Dilated, fluid-filled loops of small bowel.

2016年5月23日 · The presence of an abdominal mass or the suspicion of partial small-bowel obstruction often leads to examination of the small bowel. Unexplained diarrhea, malabsorption, and unexplained intestinal bleeding are also indications. Abdominal pain or tenderness may justify a small-bowel examination.

2019年1月22日 · CT enteroclysis is the gold standard in CT of the small bowel. There are many indications, including low-grade small bowel obstruction, IBD, obscure gastrointestinal bleeding, and small bowel tumors.

2015年10月14日 · The CT diagnosis of small bowel obstruction relies on the same definition of “dilated” small bowel encountered in other imaging modalities, including x-ray (plain radiography) and ultrasound. The normal small bowel diameter is less than 2cm; diameter greater than 3cm is uniformly abnormal.
