多层螺旋CT对急性结肠出血的临床应用价值

目的：研究多层螺旋CT对急性结肠出血的应用价值。方法：对临床可疑急性结肠出血9例患者行多层螺旋CT检查,采用动静脉双期增强扫描,并结合多层螺旋CT多平面重建、最大密度投影图像分析诊断,部分病例经手术或临床随访证实,部分与DSA对照。结果：9例临床拟诊急性结肠出血患者,多层螺旋CT明确诊断出血部位7例,出血显示率77.7...

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

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.
