The clinical value of multiparametric-MRI in the diagnosis of bladder cancer
摘要
Abstract
Objective To investigate the value of multiparametric-MRI in predicting the T stage,the infil-tration,limitation and lymph node accuracy of bladder cancer. Methods A total of 55 patients underwent HR T2WI,DWI and DCE-MRI examination.The only diagnosis and the diagnosis combined diagnosis of bladder can-cer,tumor staging and infiltration were compared,and pathological diagnosis was used as the standard.ROC curve analysis was used to analyze the value of ADC in predicting the invasion of bladder cancer. Results There were 35 cases of stage T1,15 cases of stage T2,3 cases of stage T3 and 2 cases of stage T4.The accuracy of multipara-metric-MRI in staging of bladder cancer was 87.27%,which was better than that of DWI(80.00%),DCE-MRI (74.00%).HR-T2WI(K =0.768)has some advantages over DCE-MRI(k=0.545),DWI(k=0.648)and HR T2WI(k=0.280).The accuracy of multiparametric-MRI diagnosis of myasthenic invasive bladder cancer and localized bladder cancer was 87.27%,which was better than that of HR-T2WI,DWI and DCE-MRI.The AUC of ADC value was 0.989 for diagnosis of invasive bladder and 1.54 × 10-3mm2/s for diagnostic bladder cancer. The AUC of ROC curve for non-localized bladder cancer was 0.984 and the diagnostic cutoff point 1.42 × 10-3mm2/s. Conclusions The use of Multiparametric-MRI has high diagnostic performance in the diagnosis of bladder cancer in patients with T staging,myometrial invasion and tumor extent.关键词
