CT血管成像后处理技术在肠系膜血管栓塞诊断中的应用

目的 探讨CT血管成像(CT Angiography,CTA)后处理技术在肠系膜血管栓塞诊断中的应用价值.方法 50例肠系膜血管栓塞患者,均行螺旋CT增强扫描,原始数据采用多平面重组(MPR)、容积成像(VR)和最大密度投影(MIP)方法进行后处理,观察其对明确诊断所起的作用.结果 MPR、VR和MIP方法均能显示病变,以MPR显示率最高,结合3种方法可以获得明确诊断.结论 CTA能够明确肠系膜血管栓塞的诊断,MPR进行图像后处理的价值最大.

The Application of CT Angiography Post -processing Technique in Diagnosis of Superior Mesenteric Vessel Embolism

Objective To explore the applications of CT angiography post-processing techniques in diagnosis of mesenteric vessel embolism.Methods Enhanced CT scans were performed in 50 cases of mesenteric vessel embolism.The raw data were post-processed into images for diagnosis in workstation by multi-planar reformation(MPR),volume rending(VR) and maximum intensity projection(MIP).The diagnoses were given according to post-processed images.Results All the post-processed images by MPR,VR and MIP could find mesenteric vessel embolism,especially by MPR.The diagnosis could be given by combining three post-processing technique.Conclusion CTA was good at diagnosis of mesenteric vessel embolism.MPR was the most valuable post-processing technique.
