摘　　要：目的研究MSCT不同层厚及重建方式对肾皮质厚度测量的影响。方法选取30例上腹部MSCT增强患者,分别在5mm、1.25mm层厚及MPR重建图像上测量60只肾脏上盏平面、肾门平面及下盏平面皮质厚度,对测得数据进行统计分析。结果 5mm层厚测得肾皮质上盏平面、肾门平面及下盏平面平均厚度分别为(5.54±0.954)mm、(5.59±1.195)mm、(5.45±1.048)mm;1.25mm层厚测得肾皮平均厚度分别为(5.49±1.095)mm、(5.38±1.065)mm、(5.45±1.055)mm;斜冠斜矢位上测得肾皮质平均厚度分别为(5.30±1.085)mm、(5.29±1.005)mm、(5.33±1.050)mm;三种测量方式测得数据差异无统计学意义(P>0.05)。结论不同层厚及重建方式对肾皮质厚度测量值的影响不具有统计学意义,在临床科研中可以采用5mm层厚测量肾皮质厚度,以简化研究程序。Objective To study the MSCT＇s different collimation and reconstruction influence on the measurement of renal cortical thickness. Methods Choose 30 patients with epigastric CT enhanced, Measured the renal cortical thickness respectively in the collimation of 5mm and 1.25mm MPR reconstruction images of 60 kidneys＇ upper Pole,the renal hilum, inferior pole. The three groups of data for statistic analysis. Results Measured in the collimation of 5mm, Average thickness respectively for the upper Pole, the renal hilum, inferior pole is （5.54 ± 0. 954 ）mm, （5.59 ± 1. 195 ）mm, （5.45 ± 1. 048 ）mm; Measured in the collimation of 1.25 mm is （ 5.49 ±1. 095 ） mm, （ 5.38 ± 1. 065 ） mm, （ 5.45 ± 1. 055 ） mm ; On the oblique Coronal and Sagittal position is （5.30 ± 1. 085 ） mm, （ 5.29 ± 1. 005 ） mm, （ 5.33 ± 1. 050 ） mm respectively; Statistic analysis for the three measured methods of data, There were no significant differences of statistics （ P 〉 0. 05 ）. Conclusion MSCT different collimation and reconstruction methods influence on the measurement of renal cortical thickness have no statistically significant, the collimation of 5mm can be used in the clinical research to simplify the procedures of study.
