The mean delay to post-PAE MRI was 120\u2009days. After PAE, no new PI-RADS \u22653 lesions appeared, and no lesion was upgraded. Both initially classified as PI-RADS 5 lesions (negative on biopsies) were downgraded to PI-RADS 1. Among the 6 PI-RADS 4 lesions, 3 remained stable, 2 were downgraded to PI-RADS 3, and 1 to PI-RADS 2.
