   description

   Sensitivity of VI-RADS score for invasion through the bladder wall was recorded. At the end VI-RADS scoring was calculated using all categories, to know the probability of muscle invasion as follows: VI-RADS 1 (very low probability of muscle invasion ): SC, CE, and DW category 1; VI-RADS 2 (low probability of muscle invasion): SC, CE, and DW category 2; both CE and DW category 2 with SC category 3; VI-RADS 3 (muscle invasion is equivocal): SC, CE, and DW category 3; SC category 3 and CE or DW category 3, with the remaining sequence in category 2; (Category 3 should be applied when category 2 findings are absent in their respective sequences but there is no apparent disruption of the typical SI in the muscularis propria, there may be Misclassifications in the VI-RADS 2-3 group).
