(a) 68Gallium-prostate-specific membrane antigen positron emission tomography image fused with the corresponding T2-weighted magnetic resonance imaging (b) showing focal tracer uptake (red arrow) on the side opposite to the magnetic resonance imaging-detected hypointense lesion (yellow arrow). While no obvious magnetic resonance imaging lesion is seen corresponding to the prostate-specific membrane antigen uptake. (c) T2-weighted magnetic resonance imaging of prostate showing a hypointense nodule involving the left anterior and posterior transitional zone at the base with low ADC values (d). (e) Hematoxylin and eosin-stained specimen of radical prostatectomy showing the acinar adenocarcinoma (from both right and left lobe transition zones)

PET-MRI images [Figure 1] revealed a focal 68Ga-PSMA uptake in the right transitional zone of the prostate gland involving the midgland and apex regions (red arrow).
