Cat.SignificadoCondutaRiscoFonte
1
VI-RADS 1, muscle invasion highly unlikely
Muscle invasion highly unlikely. All sequences are category 1: on T2WI an uninterrupted low-signal line indicates an intact muscularis propria; on DWI the muscle layer shows continuous intermediate signal (lesion under 1 cm); on DCE there is no early enhancement of the muscularis propria.		——

PMC6690492 (Panebianco et al., Eur Urol 2018), Sect. 3.2.5 'Final scoring' with Sect. 3.2.4.2 (T2W SC1), 3.2.4.4 (DWI cat 1), 3.2.4.3 (DCE cat 1); Table 2.
2
VI-RADS 2, muscle invasion unlikely
Muscle invasion unlikely. The low-signal muscularis line remains uninterrupted; typically an exophytic tumor with a stalk and/or a thickened high-signal inner layer on T2WI, with corresponding category-2 DWI/DCE (continuous intermediate-signal muscle on DWI for lesions over 1 cm; early enhancement of the inner layer but not the muscle on DCE).		——

3
VI-RADS 3, equivocal
Equivocal for muscle invasion. Category-2 features are absent but there is no clear interruption of the low-signal muscularis propria (e.g. exophytic tumor lacking a stalk, or a sessile/broad-based tumor without a clearly thickened inner layer). When T2WI is equivocal, DWI (first) then DCE drive the assessment.		——

4
VI-RADS 4, muscle invasion likely
Muscle invasion likely. At least one sequence is category 4: on T2WI the low-signal muscularis line is interrupted, suggesting tumor extension into the muscularis propria; DWI shows high-signal tumor (low ADC) extending focally into the muscle; DCE shows early-enhancing tumor extending focally into the muscularis propria.		——

5
VI-RADS 5, invasion of or beyond muscle very likely
Invasion of muscle and beyond the bladder very likely. Intermediate-signal tumor extends into the extravesical fat on T2WI; on DWI/DCE the high-signal or early-enhancing tumor extends through the entire bladder wall into the perivesical fat.		——
