多层螺旋CT成像在膀胱癌诊断及术前分期的价值分析

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 double-blind 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.
