膀胱癌螺旋CT诊断和分期

Spiral CT Diagnosis and Staging in Bladder Carcinoma

目的:通过螺旋CT对膀胱癌分期与病理分期的对比,评价螺旋CT对膀胱癌诊断和分期的价值。方法:使用SOMATOM、BALANCE 1s螺旋CT机,对45例膀胱癌患者进行盆腔平扫、动脉期、静脉期增强扫描。小病灶薄层扫描,观察病变的大小、形态、密度、范围、毗邻关系。结果:螺旋CT对膀胱癌的分期与病理分期符合率为87%。结论:螺旋CT对膀胱癌的诊断和分期,为临床提供最为准确的无创伤性的诊断依据和预后评估。

Objective： To compare CT staging with pathological staging in bladder carcinoma and evaluate the value of spiral CT in diagnosis and staging. Method： The pelvic plain scans, arterial and venous phase enhancement scans were performed in 45 patients with bladder carcinoma with a SOMATOM BALANCE spiral CT scanner. Thin slice scans were performed in small focus, and the size, the shape, the density, the extent and relationship with surroundings of the focus were observed. Result： Compared with pathological staging,the matchrate in spiral CT staging was 87%. Conclusion： Spiral CT scanning could provide the most accurate and noninvasive diagnosis evidence and assessment of prognosis.
