Magnetic Resonance Spectroscopic Imaging Study of Prostatic Fats to Distinguish the Difference Between High and Low Risk Prostate Cancer (MRSI+RRP)
25. april 2017 opdateret af: Jackie Shannon, OHSU Knight Cancer Institute
Imaging Prostatic Lipids to Distinguish Aggressive Prostate Cancer
A prostate cancer diagnosis starts a list of events that often leads to fast-moving treatment, thought by many to result in vast over-treatment of this disease.
So, discovery of different diagnostic methods that allow clinicians to identify slow-growing from potentially fast-growing disease prior to or at the time of prostate biopsy could result in early and suitable treatment for men at greatest risk, while greatly decreasing the number of biopsies, surgical procedures, hormonal and chemotherapeutic treatments, cost, and patient worry, for those with more slow-growing disease.

High risk prostate cancer patients
Men who have been recently diagnosed with high risk prostate cancer (Gleason score 7 and above) and who choose prostate removal for their cancer treatment will undergo Magnetic Resonance Spectroscopy Imaging (MRSI) with rectal probe at the Oregon Health & Science University's Advanced Imaging Research Center.
