Abstract
Objective: To investigate the diagnostic value of 64 multi-detector rows CT for unknown cause of acute lower gastrointestinal bleeding. Methods: Multi-planar reconstruction and CT angiography of 64 multi-detector row CT were prospectively performed in 26 cases of unknown cause of lower gastrointestinal bleeding. Results: All 26 patients were confirmed by pathology including large intestinal tumor, 13 cases(50％）, intestinal tumor, 4 cases(15.3％), intestinal obstruction, 2 cases(7.6%), hernia, 3 cases(11.5%), acute mesenteric venous thrombosis(AMVT), 3 cases(11.5%), mesenteric arterio-venous fistula, 1 case(3.8%). The diagnostic accuracy was 97%, the accuracy of predicting lesion position was 100%. Conclusion: 64 multi-detector rows CT scanning has high value for detecting the cause of intestinal hemorrhage and detecting the site of intestinal lesion.
