多层螺旋CT在大肠分区及肠壁厚度测量中的价值

Evalution of multislice spiral CT in large intestine subarea and measuring intestinal wall thickness

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:The purpose of this study was to evaluate the value of Multi-spiral CT in large intestine subarea and measuring intestinal wall thickness.Methods:A study of 50 adults (with no intestinal disease) underwent multi-spiral scans. Including: All adults were scanned with 2D and axial imaging using multi-spiral CT and 28 adults underwent dual-phase contrast within one breathhold each. All multi-spiral CT image was reviewed by two radiologist who were subarea and measured the intestinal wall thickness.Results:All adults were correctly subarea and were measured intestinal wall thickness of different district.Conclusion:Multi-spiral CT could not only be subarea from more planes and angles, but also be useful in measuring intestinal wall thickness of different district.
