Role of MRI in the Current Management of Prostate Cancer – Summary:

Dov Kadmon, MD, discusses the role of MRI in the diagnosis, staging, and surveillance of prostate cancer. He then reviews two high quality studies that evaluate the possibility of MRI guided biopsies as an alternative to standard ultrasound biopsies.


The role of MRI in prostate cancer is still being defined. However, we have witnessed increased utilization of MRI in prostate cancer management. Local and regional staging, as well as selection of patients for targeted biopsy, are the main applications.

Two large recent studies similarly support the use of MRI fusion biopsies in biopsy naïve patients. The first study, termed “PROMIS,” was published in Lancet in 2017.(1) This study showed that the sensitivity of multiparametic MRI for detecting clinically significant prostate cancer was 88% (compared to 48% for the regular ultrasoun-guided 12 cone biopsy).

Secondly, the New England Journal of Medicine published the study termed the “PRECISION” trial in 2018.(2) During this study, more patients undergoing MRI-guided biopsies had clinically significant disease (38% versus 26%). Conversely, fewer patients were diagnosed with clinically insignificant cancers (9% versus 22%). Furthermore, 28% of the patients avoided biopsy altogether based on a negative prostate MRI.

At the present time, guidelines set by the National Comprehensive Cancer Network (NCCN), American Urological Association (AUA), and European Association of Urology (EAU) support the use of MRI-targeted biopsies in patients having repeat biopsies following negative previous biopsies. However, the consensus is that there is no yet sufficient evidence to declare the MRI-guided biopsy as the “gold standard.”

At our institution, we started an MRI/ultrasound fusion biopsy program during the past three years. So far, we performed 275 fusion biopsies. We have learned quality control is paramount, starting with the MRI technician and ending with the urologist performing the biopsy.

About Innovations in Urologic Practice

Innovations in Urologic Practice (IUP) is an annual CME-accredited conference devoted to updating urologists on the rapidly changing healthcare environment. Topics focus on innovative diagnostic and treatment strategies, controversies, new and currently developing technologies, and challenges in today’s urologic practice. Dr. Kadmon presented this lecture during the 23rd IUP in 2018. Please visit this page in order to learn more about future IUP meetings.
