The Value Clinical Application of Multi-slice Spiral CT in Acute Colon Hemorrhage

Abstract：Objective：To explore the diagnostic value of multi-slice spiral CT in acute colon hemorrhage.Methods：9 patients with clinically suspected acute colon hemorrhage were all examined using multi-slice spiral CT,The patients were performed Dual-phase enhanced scan using multi-modal reorganization such as multiplanar reconstruction,maximum intensity projection image,most cases were confirmed by surgery or clinical follow-up.The others cases were confirmed by DSA.Results：In 9 clinically suspected cases of actue colon hemorrhage,hemorrhagic lesions were confirmed in 7cases（positive detection rate of multi-slice spiral CT in diagnosis of colon was 77.7 %（7/9）.Inthese11cases,DSA were performed in4 cases with a result of 3positive and 1negative.positive detection rate of DSA was 75.0 %（3/4）.There were 2 cases no signs of hemorrhage were found by multi-slice spiral CT in 9 cases,DSA was also negative.Sites of hemorrhage depicted by multi-slice spiral CT were as follows：ascending colon hemorrhage（n = 2）,descending colon（n = 4）,rectum（n = 1）,while the pathological nature of the hemorrhagic lesions was ulcer in 2 cases,tumor in 3 cases,and inflammation in 2cases.Conclusion：multi-slice spiral CT with dual-phase enhanced scan and construction techniques plays an important role in diagnosis of actue colon hemorrhage.
