摘要
目的:探讨多层螺旋CT成像在膀胱癌诊断及术前分期的应用价值。方法:回顾性分析2008年5月-2012年6月本院确诊治疗的83例膀胱癌患者的术前分期情况,所有患者分别应用二维超声扫描检测和多层螺旋CT成像扫描(简称螺旋CT)检测,通过2名经验丰富医师采用双盲法进行阅片并进行术前膀胱癌T分期,统计分析两种检测方法对膀胱癌患者癌灶检出情况、分期情况。结果:83例患者中,螺旋CT检测对患者膀胱各部位癌灶检出个数均高于二维超声检测,前者总癌灶检测个数明显高于后者,差异均有统计学意义(P<0.05)。螺旋CT检测对膀胱癌术前T分期的特异度为96.38%、敏感度为85.27%,准确率为93.34%;二维超声检测对膀胱癌术前T分期的特异度为88.54%、敏感度为79.62%,准确率为85.81%,前者明显高于后者,差异均有统计学意义(P<0.05)。结论:多层螺旋CT成像检测可作为膀胱癌诊断的有效方法,可有效提高对膀胱癌术前T分期的准确度,有助于医师制定相应的治疗方案,值得临床作进一步推广。
Objective： To investigate the value of multi-slice CT imaging in the diagnosis and preoperative bladder cancer before staging.Method： 83 cases of preoperative staging of bladder cancer diagnosis treatment in our hospital from May 2008 to June 2012 were retrospective analyzed, all patients were two-dimensional ultrasound scanning and multi-slice CT imaging scan（referred to as spiral CT） detected by two experienced physicians read the piece doubleblind method and preoperative staging of bladder cancer T, statistical analysis of the two detection methods in detection of bladder cancer foci, staging situation. Result：83 cases of bladder cancer, spiral CT detection of various parts of the patients with bladder cancer foci were higher than those detected in the number of two-dimensional ultrasound detection, the former total number of detected foci were significantly higher than the latter, the difference were statistically significant（P〈0.05）; spiral CT detection of bladder cancer before surgery specificity T staging of 96.38%, a sensitivity of 85.27%, accuracy was 93.34%, a specificity of two-dimensional ultrasound detection of bladder cancer before surgery T staging was 88.54%, the sensitivity was 79.62%, accuracy was 85.81%, significantly higher than the former to the latter, the difference were statistically significant（P〈0.05）. Conclusion： Spiral CT imaging can be used as an effective method to detect bladder cancer diagnosis, which can effectively improve the accuracy of preoperative T staging of bladder cancer before, helping physicians develop appropriate treatment programs worthy of further promotion.
