An elevated PSA often leads to an important question: should you have a prostate biopsy right away, or is an MRI the better first step?
In this episode of Intellectual Medicine, Dr. Stephen Petteruti explains why multiparametric MRI has become an essential tool in evaluating men at risk for prostate cancer before proceeding to biopsy.
Dr. Petteruti discusses how MRI helps identify suspicious areas within the prostate, the role of the PI-RADS scoring system, and why imaging can provide valuable information that guides decision-making. He also explains the limitations of prostate biopsies, including sampling error and the challenge of drawing broad conclusions from a relatively small tissue sample.
The conversation explores how PSA trends, MRI findings, and clinical judgment work together to determine the most appropriate next steps. Dr. Petteruti also discusses active surveillance and emphasizes the importance of patients understanding their diagnostic options so they can make informed decisions in partnership with their physician.
