MRI And GPS Informing Choices for Prostate Cancer Treatment (MAGIC)

The Genomic Prostate Score is a 17 gene relative expression assay used to predict the presence of adverse pathologic findings at radical prostatectomy. This test is used to determine appropriateness for active surveillance. Prostate MRI is a prostate imaging test that has been shown to improve the detection of clinically significant prostate cancer using a PI-RADS scoring system. It relies on T2-weighted imaging, diffusion weighted imaging, dynamic contrast enhancement, and apparent diffusion coefficient to differentiate prostate cancer from normal prostate parenchyma and prostatitis.
