Figure 4.
On the MRI scan of the prostate a suspect PI-RADS-4- lesion is detected (yellow arrow) in the peripheral zone on the left side. Image fusion yields a fusion guided prostate biopsy (red arrow) of a suspect prostate lesion. GPS tracking (blue marker T1) correlates well with the lesion in both modalities. Histology confirmed a poorly differentiated acinar prostate carcinoma (Gleason score 3 + 4 = 7a).
