Multifocality and Prostate Cancer Detection by Multiparametric Magnetic Resonance Imaging: Correlation with Whole-mount Histopathology  Jesse D. Le, Nelly Tan, Eugene Shkolyar, David Y. Lu, Lorna Kwan, Leonard S. Marks, Jiaoti Huang, Daniel J.A. Margolis, Steven S. Raman, Robert E.

2 Fig. 1 Results for a 62-yr-old male with intermediate-risk prostate cancer (biopsy Gleason score 4+3, prostate-specific antigen 11 ng/ml) and two high-suspicion regions of interest (image grade 4/5) at the mid-gland on multiparametric magnetic resonance imaging (MRI) performed with (A) T2-weighted imaging, (B) dynamic contrast-enhanced, and (C) diffusion-weighted imaging. (D) Both the left-sided index tumor (Gleason 3+4) and right-sided tumor (Gleason 3+3) observed on radical prostatectomy were detected by MRI; two additional small foci of Gleason 3+3 were missed.

3 Fig. 2 Rate of tumors detected and missed by multiparametric MRI, as stratified by maximal tumor diameter, Gleason score, index status, and tumor focality for all unique tumor foci (n=283). The index tumor is that with the highest Gleason score; if multiple foci had the same grade, the largest was considered the index lesion.

4 Fig. 3 Rate of tumors detected and missed by multiparametric magnetic resonance imaging, as stratified by maximal tumor diameter, Gleason score, and index status for solitary tumors (n=44, top) and multifocal tumors (n=239, bottom).
