64层螺旋CT行结肠检查后图像后处理技术的应用价值

Application value of image post-processing technology after 64-slice CT colon examination

目的：探讨64层螺旋CT及后处理技术在大肠肿瘤方面的诊断及临床应用价值。方法：对56例患者应用西门子64层螺旋CT进行全腹容积扫描，在工作站应用图像后处理技术，应用MIP、VR、VE获得图像，并与结肠镜或/和手术病理对照观察。结果：56例中有42人检出大肠病变，共检出病灶47个，其中一人检出3个病灶，另外3人检出2个病灶。对照病理，影像诊断准确率为100％。结论：64层螺旋CT行结肠检查后图像后处理技术对于大肠病变的诊断具有独特的优越性。

AIM：To investigate the value of 64-slice CT and post-processing technology in the large intestine tumor diagnosis and clinical application.METHODS：56 cases of patients received whole abdomen volume scanning by 64-slice CT.We applied image post-processing technology in workstation,and got the image by MIP,VR,VE,and compared with colonoscopy and/or surgical pathology.RESULTS：There were 42 patients with colon lesions and 47 lesions totally,one of them had 3 lesions,other 3 people had 2 lesions.The accuracy rate of imaging diagnostic was 1 00% comparing with pathology.CONCLUSION：The 64-slice CT image post-processing after colon examination technique has unique advantages for the diagnosis of colon lesions.
