摘要
目的探讨多层螺旋CT增强及三维成像诊断膀胱癌的临床价值。方法选取疑似膀胱癌患者50例,所有患者均接受多层螺旋CT扫描、膀胱镜检查并取活组织标本进行病理检查。用卡方检验分析多层螺旋CT增强扫描和膀胱镜检查对不同部位膀胱癌的检出情况;计算多层螺旋CT增强扫描诊断膀胱癌的灵敏度、特异度。结果多层螺旋CT增强检查和膀胱镜检查对左侧壁、右侧壁、三角区、前壁、顶壁、多发膀胱癌的检出率之间的差异无统计学意义(P>0.05)。活组织病理检查诊断膀胱癌阳性38例,阴性12例。多层螺旋CT诊断膀胱癌阳性39例,阴性11例;膀胱镜检查诊断膀胱癌阳性40例,阴性10例。和活组织病理检查对比,多层螺旋CT诊断膀胱癌的灵敏度94.7%(36/38),特异度为75.0%(9/12),准确度为90.0%(45/50),阳性预测值为92.3%(36/39),阴性预测值为81.8%(9/11)。和活组织病理检查比较,膀胱镜诊断膀胱癌的灵敏度97.4%(37/38),特异度为75.0%(9/12),准确度为92.0%(46/50),阳性预测值为92.5%(37/40),阴性预测值为90.0%(9/10)。结论多层螺旋CT增强及三维重建诊断膀胱癌的灵敏度、特异度均较高,有较好的临床应用价值。
Objective To explore the clinical value of multi-slice spiral CT enhancement and three-dimensional imaging in the diagnosis of bladder cancer.Methods 50 patients with suspected bladder cancer were selected retrospectively.All patients underwent multi-slice spiral CT scan,cystoscopy and biopsy.Chi square test was used to analyze the detection of bladder cancer in different parts by MSCT and cystoscopy,and to calculate the sensitivity and specificity of MSCT in the diagnosis of bladder cancer.Results There was no significant difference in the detection rate of left wall,right wall,triangle area,anterior wall,parietal wall and multiple bladder cancer between MSCT and cystoscopy(P>0.05).The diagnosis of bladder cancer was positive in 38 cases and negative in 12 cases.MSCT was positive in 39 cases and negative in 11 cases;Cystoscopy was positive in 40 cases and negative in 10 cases.The sensitivity,specificity and accuracy of MSCT were 94.7%(36/38),75.0%(9/12)and 90.0%(45/50),respectively,The positive predictive value was 92.3%(36/39)and the negative predictive value was 81.8%(9/11).The sensitivity,specificity,accuracy,positive predictive value and negative predictive value were 97.4%(37/38),75.0%(9/12),92.0%(46/50),92.5%(37/40)and 90.0%(9/10)respectively.Conclusion The sensitivity and specificity of MSCT enhancement and three-dimensional reconstruction in the diagnosis of bladder cancer is high,and it has better clinical application value.
