摘    要:目的:探讨多层螺旋CT(MSCT)曲面重建(CPR)肠管成像技术在肠道病变诊断中的临床应用价值。方法:42例肠道病变患者,十二指肠腺癌3例,空肠脂肪瘤1例,回肠淋巴瘤1例,回肠平滑肌肉瘤1例,回肠腺癌4例,回肠及结肠Crohn病1例,结肠腺癌19例,结肠淋巴瘤1例,直肠腺癌11例。采用10mm层厚层距行全腹部MSCT容积扫描,获得原始数据,用2.5mm层厚、1.25mm间隔重叠50%重建轴面源像(ASI),传输至AW4.0诊断工作站,用reformat软件行局部肠管多平面重建(MPR),获得冠状面、矢状面及任意斜面肠管图像,再沿肠管走行划曲线进行CPR成像。结果:CPR肠管成像成功率为100%,图像清晰,均清楚地显示肠道病变。结论:CPR技术可获得良好的肠管图像,CPR肠管成像可直观地显示肠道病变,是对轴位CT图像一种很好的补充。

关 键 词:肠疾病  体层摄影术,X线计算机

Abstract:Objective: To explore the value of clinical application of multislice spiral CT(MSCT) curved planar reconstruction(CPR). Methods: The whole abdominal MSCT volume scanning of 42 patients was performed with a 10mm collimation thickness and interval in a single breath-hold. The CT axial images were reconstructed to bring out axial source images(ASI) with a 2.5mm collimation thickness and 1.25mm interval. The data of ASI was conveyed to workstation and dealt with multiplanar reconstruction(MPR). CPR was performed again after MPR. Results: The successful rate of CPR technique was 100%. CPR with high quality could be obtained with MSCT to show the intestinal disease clearly. Conclusion: CPR can directly display intestinal disease. CPR is an efficient supplement to CT axial images.
Keywords:intestinal diseases  tomography   X-ray computed
