摘　　要：目的　评价CT仿真胆囊内窥镜 (CTVEGB)和口服胆囊造影CT(OCCT)对胆囊息肉的显示能力。方法　选择 3 2例经手术病理证实的胆囊息肉患者 ,作OCCT并与CTVEGB比较。结果　OCCT检出 76/ 96枚 (79.2 % ) ,CTVEGB检出 90 / 96枚 (93 .8% ) (χ2 =7.5 2 ,Ρ <0 .0 1)。CTVEGB比OCCT更精确显示息肉的三维形态 ,并可在三维空间以任意角度观察 ,对息肉病变大小、形态、部位的显示与手术病理结果具有良好的对应性。结论　CTVEGB可作为一种准确而无创伤性的检查方法 。Objective To evaluate the display ability and clinical application of CT virtual endoscopy(CTVEGB) and cholangiographic CT(OCCT)on polyps of the gallbladder.Methods 32 cases with polyps of the gallbladder proved by surgery and pathology were examined with OCCT and CTVEGB.Results The accuracy rate of OCCT and CTVEGB were 79.2%(76/96) and 93.8%(90/96)(χ 2=7.52,Ρ< 0.01)respectivily.CTVEGB could more correctly demonstrate the surface details of polyps which were viewed in a 3D fashion in any projection than OCCT.CTVEGB was corresponded well with operation and pathology in demonstrating the size,figure and place of the lesions.Conclusion CTVEGB is a noninvasive and accurate procedure,which has a important value in clinic application.
