目的 :应用多层螺旋CT成像技术对大肠进行分区并对各区肠壁厚度进行测量 ,旨在测量并制定各区肠壁厚度的正常值。方法 :对 5 0例正常成年人应用多层螺旋CT进行腹部扫描 ,并对其中的 2 8例进行双期强化扫描 ,按大肠的解剖分区法对各被检者大肠的MPR冠状重建图像进行分区 ,并应用光标分别测量各区肠壁厚度。结果 :5 0例被检者大肠的MPR重建图像均能比较准确地对大肠进行分区 ,测量并计算出各被检者各区肠壁厚度的正常值 ,分别为盲肠 :2 .33± 0 .1 4 ,升结肠和横结肠区 :4 .4 5± 0 .32 ,降结肠和乙状结肠 :2 .36± 0 .1 9,直肠 :3.5 8± 0 .2 5。结论 :多层螺旋CT能够比较准确地对大肠进行分区 ,测量并计算出正常人不同区域肠壁厚度的正常值。
OBJECTIVE: To apply multi-slice spiral CT imaging technique to segment the large intestine and measure the thickness of the intestinal wall in each area. The purpose is to measure and make the normal thickness of the intestinal wall in each area. Methods: Fifty normal adults were examined by multi-slice spiral CT, and 28 of them underwent double-phase intensive scanning. The large intestine’s MPR coronal reconstruction images were divided according to the method of large intestine anatomy , And the cursors were used to measure the thickness of intestinal wall in each area. Results: The images of the MPR in 50 cases of the testis were able to segment the large intestine more accurately. The normal values of the intestinal wall thickness were measured and calculated in each area of the subjects: caecum: 2.33 ± 0. 1 4, ascending colon and transverse colon region: 4.54 ± 0.32, descending colon and sigmoid colon: 2.36 ± 0.11, rectum: 3.5 8 ± 0.52. Conclusion: MSCT can segment the large intestine more accurately and measure and calculate the normal thickness of the intestinal wall in different regions of normal people.
