多层螺旋CT三维成像技术在膀胱癌诊断中的临床应用价值

Study on the clinical value of the multi-slice spiral CT three-dimensional imaging in the diagnosis of bla-dder carcinoma

目的探讨多层螺旋CT三维成像技术对膀胱癌的诊断价值。方法选取本院就诊的有血尿史且高度怀疑为膀胱癌的患者60例为研究对象,分别采用多层螺旋CT扫描及图像后处理与纤维膀胱镜检查并取组织标本活检,比较分析两种检测方法对膀胱癌的检出情况及对膀胱癌不同病灶的发现情况,并分析多层螺旋CT三维成像技术对膀胱癌诊断的真实性和准确性。结果 60例患者中行纤维膀胱镜检查及病理活检后共54例确诊为膀胱癌,多层螺旋CT三维成像技术检出膀胱癌患者50例,多层螺旋CT三维成像技术与纤维膀胱镜对三角区、右侧壁及左侧壁膀胱癌病灶的检出率比较差异均无显著性(P>0.05);多层螺旋CT三维成像技术对膀胱癌诊断的灵敏度为90.7%,特异度为83.3%,阳性预测值为98.0%,阴性预测值为50.0%,正确指数为74.0%。结论多层螺旋CT三维成像技术对膀胱癌的检出率较高,具有一定的诊断价值。

ObjectiveTo explore the clinical value of the multi-slice spiral CT three-dimensional imaging in the diagnosis of bladder carcinoma.MethodCollected 60 patients who had the history of hematuria and suspected bladder carcinoma in our hospital as objects of study, adopted multi-slice spiral CT three-dimensional imaging and ifber cystoscopy and biopsy of tissue specimen, compared the detection rate of bladder carcinoma and the different lesions found in bladder carcinoma between the two methods, analyzed the authenticity and reliability of multi-slice spiral CT three-dimensional imaging on bladder carcinoma.Result54 cases of bladder carcinoma were detected from 60 cases of patients by using ifber cystoscopy and biopsy, 50 cases of patients with bladder carcinoma were detected from 60 cases of patients by using multi-slice spiral CT three-dimensional imaging, the differences of detection rate of bladder trigone, wall of the right side and the left side of the bladder carcinoma lesions between multi-slice spiral CT three-dimensional imaging and ifber cystoscopy were not signiifcantly different （P〉0.05）; sensitivity of multi-slice spiral CT three-dimensional imaging in the diagnosis of patients with bladder carcinoma was 90.7%, speciifcity was 83.3%, positive predictive value was 98.0%, negative predictive value was 50.0%, the correct index was 74.0%.ConclusionMulti-slice spiral CT three-dimensional imaging has high detection rate on bladder carcinoma, it has accurate and reliable value.
