目的 评价CT仿真胆囊内窥镜 (CTVEGB)对胆囊息肉的显示能力和临床应用价值。方法 选择 32例经手术病理证实的胆囊息肉患者 ,口服对比剂行胆囊CT仿真内窥镜成像并与彩色超声 (简称彩超 )比较。结果 彩超检出 93/96枚 (96 .9% ) ,CTVEGB检出 90 /96枚 (93.8% ) (χ2 =0 .46 6 ,P >0 .0 5 )。CTVEGB比彩超可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、部位的显示与彩超检查及手术病理结果具有良好的对应性。结论 CTVEGB可作为1种准确而无创伤性的检查方法 ,具有较高的临床应用价值
Objective To evaluate the ability of CT virtual cyst endoscopy (CTVEGB) to display gallbladder polyps and its clinical value. Methods Thirty - two cases of gallbladder polyps confirmed by surgery and pathology were selected. Computed tomography endoscopy (CT) was performed with oral contrast agent and compared with color ultrasound. Results 93/96 (96.9%) were detected by color Doppler ultrasound and 90/96 (93.8%) by CTVEGB (χ2 = 0.46 6, P> 0.05). CTVEGB can display the three-dimensional shape of polyps more accurately than color Doppler ultrasound and can be observed at any angle in three-dimensional space. CTVEGB has a good correspondence with the size, shape and location of polyposis and the results of color Doppler ultrasound examination and surgical pathology. Conclusion CTVEGB can be used as an accurate and non-invasive examination method, with high clinical value
