摘要
目的利用多层螺旋CT人肠系膜动脉成像与尸体标本上观察的肠系膜动脉进行对照,测量评价肠系膜动脉。方法选取正常人230例,腹部多层螺旋CT增强扫描,将图像进行后处理、三维重建后观测肠系膜动脉,然后对正常肠系膜动脉的多层螺旋CT图像与尸体解剖标本的肠系膜动脉进行分析比较。结果1.活体扫描成像测量人肠系膜动脉,其管径明显大于尸体标本肠系膜动脉测量值(P<0.05);2.肠系膜上动脉和肠系膜下动脉起始位置、分支类型及走行与已有尸体标本的资料结果有较大的差异;3.不同的重建方法各有其优越性,其中,STS-MIP重建能较好地显示肠系膜动脉分支的级别。结论多层螺旋CT增强扫描,通过工作站三维重建能较好地显示肠系膜动脉,并对其进行科学评价,其数据可靠,并可以进行大样本的测量研究。
Objective To measure and evaluate mesenteric artery by comparing the multi-slice spiral CT mesenteric artery images with autopsy specimens. Methods Totally 230 normal subjects were selected to undergo abdominal multi-slice spiral CT and enhanced CT. We processed the images, reconstructed 3D images, analyzed and compare the mesenteric artery images obtained by muhi-slice spiral CT with autopsy specimens. Results 1. Diameters of mesenteric artery obtained by vivo image were significantly larger than that of autopsy specimens （ P 〈 0. 05 ） ; 2. Start locations, branch types and running directions of both superior mesenteric artery and inferior mesenteric artery were much different between traditional autopsy specimens information and our results. 3. Different reconstruction methods had different advantages. Especially, STS-MIP method could present the level of mesenteric artery better. Conclusion The method for mesenteric artery study using multi-slice spiral CT can enhance scanning and 3D reconstruction with workstation has been approved to work well, and it is superior to traditional autopsy specimen method. It is also convenient for mesenteric artery scientific evaluation. The result data of this method are reliable. Moreover, this method is available to research with large number of specimen.
