摘　　要：目的探讨多层螺旋CT曲面重建(CPR)在体部管道中的应用价值。方法用Ph ilipsMx8000多层螺旋CT对50例体部管道疾病及邻近器管疾病患者行多层螺旋CT扫描。在工作站上对感兴趣管道做多平面重建(MPR)的冠状面、矢状面及任意角度斜面重建,以其中一断面作为参考面,对所选管道行CPR,使弯曲的管道在一幅图像上直观地显示。结果50例患者中,3例属正常管道,CPR图像清晰显示其全貌及与周围器官的关系;其余47例均显示有不同部位和范围的病变。结论CT CPR能展示体部各种弯曲管道的全程,清晰显示病变的位置、范围及与邻近结构的关系,是横断图像及MPR的重要补充。Objective To study the method and diagnostic value of curved planar reformation （CPR） of body canals with multislice spiral CT. Methods 50 patients with various disease of chest and abdomen scanned by muhislice spiral CT. CPR of canals of chest and abdomen were performed. Results The images of CPR were acquired satisfactory in all cases. 3 cases were normal. There were vascular diseases of chest in 6 cases,lung cancer in 9 cases,disease of abdominal vessels in 10 cases,disease of biliary tract in 10 cases. Carcinoma of the head of pancrease in 4 cases, ureter cancer in 4 cases, ureter stone in 2 cases, tuberculosis of ureter in 1 case, malformation of ureter in 1 case. Conclusion CPR of body canal with muhislice spiral CT is an effective method in the diagnosis of various diseases of chest and abdomen. It is an useful supplement of routine CT scan.
