MRI for Active Surveillance in Prostate Cancer: How I Do It

Active surveillance (AS) is an option for deferring or avoiding immediate treatment of low- to intermediate-risk prostate cancer by monitoring the disease to detect progression. Serial MRI enhances patient selection for AS and allows noninvasive monitoring of tumor progression. We have used MRI routinely at entry and during AS in a tertiary referral center for approximately 20 years. The Prostate Cancer Radiological Estimation of Change in Sequential Evaluation (PRECISE) scoring system aims to s
