摘　　要：目的 :探讨 CT仿真结肠镜 (CTVC)诊断结肠疾病的价值。材料和方法 :用螺旋 CT对 4 2例怀疑有结肠疾病的患者进行 CTVC检查 ,并结合多层面重建 (MPR)图像 ,与纤维结肠镜或手术病理结果进行对照研究。结果 :CTVC及 MPR能显示较大病灶 ,诊断率高 ,但对小病灶 ,特别是对小于 5 mm的病灶敏感性较差。结论 :CTVC是一种非侵入性的诊断方法 ,并结合 MPR图像 。Objective To evaluate the usefulness of CT virtral colonoscopy (CTVC) in the diagnosis of colonopathy. Methods 42 patients with suspectable colonopathy underwent CTVC using helical CT and combined with multiple planner reconstruction (MPR) images were compared with fibercolonoscopy or surgical pathology results. Results CTVC and MPR can reveal big lesions, but have low sensitivity in small lesions, especially in the lesions of diameter smaller than five mm. Conclusion CTVC is a non invasive method and can play an important role in the diagnosis of colonopathy combined with MPR images.
