摘　　要：目的:探讨多层螺旋CT(MSCT)多平面重组(MPR)技术在腹腔巨大囊性病变的诊断价值。方法:回顾性分析28例经临床手术病理证实的A、B、C 3组腹腔巨大囊性病变的CT影像,A组为螺旋CT横断面影像,B组为MPR(multiple planar reconstruction,MPR)影像,C组为螺旋CT横断面并辅以MPR影像,对比分析A、B、C 3组对病变定位及定性诊断与手术病理诊断符合率。结果:A组确定病变部位13例(46.43%)、病变性质14例(50%),B组确定病变部位18例(64.28%)、病变性质17例(60.71%),C组确定病变部位23例(82.14%)及病变性质23例(82.14%)。A、B、C 3组对病变定位及定性诊断差异有统计学意义(P<0.05),A、B两组对病变定位及定性的诊断无统计学意义(P>0.05),而C组对病变定位和定性诊断方面均优于A或/和B组,A组与C组比较有统计学意义(P<0.05)。结论:对于腹腔巨大囊性病变,多层螺旋CT横断面辅以MPR技术可较准确的显示病变的部位、形态、范围及周围结构关系,对临床诊断和治疗有重要价值。Objective： Explore and discuss the value of multi-slice spiral CT （MSCT） multiple planar reconstruction technique in di- agnosing the abdominal giant cystic lesions. Methods： 28 cases of CT findings of giant cystic lesions in abdomen proved by pathology were retrospectively analyzed ,which were classified into group A （axial spiral CT images） , group B （MPR post-processing images） and group C （axial spiral CT images with MPR post-processing images） ,and their lesion localization, qualitative diagnosis and surgical pa- thology were comparatively analyzed. Results： In group A,the lesion locations of 15 cases （53.57%） were confirmed,and 14 cases （50%） were qualitatively confirmed,and that of group B were 18 cases （64.28%） and 17 cases （60.71%）. In group C the lesion locations of 23 cases （82.14%） were confirmed,and 23 cases （82.14%） were qualitatively confirmed. Group C is superior to group A or/and B. There was no significant difference between group A and group B （P 〉 0. 05 ）. The differences between group A and group C were statistically valid （P 〈 0. 05）. Couclusion：MSCT multiple planar reconstruction technique has high clinical value in di- agnosis and treatment of abdominal giant cystic lesion. It is because it can provide the information of position, shape and range of peri- toneal cystic lesions.
