【摘要】 目的:评价CT仿真膀胱镜在检测膀胱病变中的作用。材料和方法:30例怀疑膀胱异常病例经膀胱镜和CT仿真膀胱镜检查,采用常规增强CT扫描后30min～1h,膀胱充盈高密度造影剂后,再行膀胱区扫描,层厚3mm,Pitch=1.5,并在工作站重建;分别由两位有经验的放射科专家独立观察CT仿真膀胱镜结果,并与病理对照。结果:传统膀胱镜检查发现异常病变27例,其中膀胱肿瘤20例,膀胱炎症6例,膀胱憩室3例,神经源性膀胱1例。在CT仿真膀胱镜中发现24例,其中6例膀胱炎症未发现。所有病人均能很好耐受CT仿真膀胱镜检查,没有并发症出现。结论:CT仿真膀胱镜检查是一种比较准确的检测膀胱病变的方法,相对于传统的膀胱镜,它没有任何并发症。更多还原

【Abstract】 Purpose: To investigate the utility of computed tomography(CT) virtual cystoscopy in the detection of bladder lesions. Materials and Methods: 30 patients suspected or known to have bladder lesions underwent CT virtual cystoscopy and conventional cystoscopy. 30 bladder lesions were filled with contrast medium after injection.An non - enhanced scan was first performed, followed by an examination in the early phase of contrast medium enhancement. Further images were acquired after adequate filling of the bladder with contrast medium, approximately 30 - 60min after injection. These data were transferred to a separate graphic computer workstation and reconstructed. Two radiologists blinded to the results of conventional cystoscopy independently reviewed the CT transverse section and virtual images, with consensus reading for cases with discrepant results. The results were then compared with the cystoscopic and histopathological findings.Results: 24 of 27 lesions detected on conventional cystoscopy, were visualized on virtual cystoscopy. 16 of 27 were bladder neoplasm(mean size 2. 6cm, range 0.4 - 7cm), 8 of 20 masses were measured less than 1cm in maximum diameter. 6 of 27 were cystitis; 3 of 27 were diverticulum of bladder. Virtual cystoscopy,was well tolerated by all patients,and no complication occurred.Conclusion: Virtual cystoscopy is an accurate technique for detection of intrinsic bladder lesion compatible to conventional cystoscopy without complication.It may serve as initial evaluation for hematuria and follow up after tumor resection.更多还原
