MSCT ANATOMY OF SMALL INTESTINEOnly 14 pages are availabe for public view
Abstract
The most common small intestinal lesions include inflammation, neoplasms, malabsorption and vascular diseases. The diagnosis of small intestinal lesions is usually based on using different diagnostic procedures, including GIT enodoscopies; capsule enteroscopy and barium meal follow through, US, CT, MRI and angiography.
Increased speed and resolution of MSCT made it a first-line modality for the examination of small bowel disease. MSCTE differs from routine abdominopelvic CT in that it makes use of thin sections and large volumes of enteric contrast material to better display the small bowel lumen and wall. The use of neutral enteric contrast agents such as water combined with intravenously administered contrast material permit excellent assessment of hypervascular lesions due to inflammation or neoplasms.
This technique can also demonstrate the level and cause of obstruction as well as signs of threatened bowel viability and to exclude other causes of an acute abdomen. This makes it particularly valuable in the acute clinical setting.
Although conventional barium meal follow through and capsule endoscopy are the most common procedures used to visualize mucosal abnormalities, their use in evaluating the mural and extramural extents of small-bowel tumors is limited. In contrast to these modalities, MSCTE has the potential to simultaneously depict intraluminal, mural, and extraintestinal abnormalities.
In conclusion, MSCTE with negative oral contrast medium in addition to intravenous iodinated contrast injection is a safe and well tolerated technique that is easily done and is sensitive to early intestinal wall changes. This technique is complementary to other imaging methods, endoscopy and laboratory studies for full assessment of the small intestinal diseases.
