作者对12例病人行膀胱CT仿真内窥镜(computed tomography virtual endoscopy,CTVE)检查,获得类似纤维膀胱镜的观察效果,进而评价其临床应用价值及限度。12例临床上有血尿并经B超检查怀疑膀胱恶性肿瘤的患者中,男8例,女4例,年龄39～88岁。以上病例均行纤维膀胱镜检查,对可疑病变取活检并经病理证实。在B超证实膀胱充盈良好的情况下,对全部12例病人行双螺旋CT容积扫描。扫描参数:120kV,250mAs,双准直2.5mm(有效层厚3.2mm),床速5mm/s。扫描分为三期:平
The authors performed a computed tomography virtual endoscopy (CTVE) examination of 12 patients to obtain the observation effect of similar cystoscopy, and then evaluate the clinical value and limits. Twelve cases of clinically hematuria and B-ultrasound in suspected bladder cancer patients, 8 males and 4 females, aged 39 to 88 years. The above cases were performed cystoscopy, biopsy suspicious lesions and confirmed by pathology. All patients underwent a double-helical CT volume scan on B-mode confirmed bladder filling. Scanning parameters: 120kV, 250mAs, double collimation 2.5mm (effective layer thickness 3.2mm), bed speed 5mm / s. The scan is divided into three phases: flat
