Background:Vesical Imaging-Reporting and Data System(Ⅵ-RADS)was developed as a structured reporting tool to anticipate the possibility of muscle *** study is aimed to investigate the diagnostic accuracy ofⅥ-RADS for discriminating T2 from T1 bladder *** and methods:Scopus,Web of Science,PubMed,and Embase were searched on October 4,2021,for studies with the following characteristics:(1)bladder cancer patient population,(2)Ⅵ-RADS as an index test,(3)retransurethral resection of bladder tumor/cystectomy as a reference,and(4)adequateⅥ-RADS score data for T1 and T2 *** analyses were performed using the binary regression model of MIDAS in ***:Six studies with 624 magnetic resonance imaging reports were *** receiver operating characteristics curve for differentiation of T2 from T1 bladder cancer showed an area under the curve of 0.93(95%confidence interval[CI],0.91-0.95)for aⅥ-RADS≥3 and 0.75(95%CI,0.71-0.79)for aⅥ-RADS≥4.AⅥ-RADS≥3 showed high sensitivity of 93%(95%CI,85%-97%),specificity of 61%(95%CI,30%-86%),positive likelihood ratio of 2.4(95%CI,1.1-5.3),and negative likelihood ratio of 0.11(95%CI,0.05-0.24).A total of 10.4%of T2 lesions were scored asⅥ-RADS 2,while 10%of T1 lesions were scored asⅥ-RADS 4 or ***:TheⅥ-RADS≥3 has high accuracy and sensitivity for detecting muscle invasion in borderline populations of T1 or T2 bladder ***,theⅥ-RADS could be a good non-invasive screening test for the detection of T2 urothelial lesions.
