Contrast CT in Localization of Acute Lower Gastrointestinal Bleeding
Localization of the source of acute lower gastrointestinal bleeding is of paramount importance in its management as it allows for planned segmental resection rather than a “blind” abdominal total colectomy. Various methods of localization with radionuclide scan, mesenteric angiography and colonoscop...
