Fig. 8.

Coronal pelvic slice of a ⁶⁸Ga-PSMA PET-MRI study dissecting the prostate gland, demonstrating loss of diagnostic accuracy at different PET acquisition durations per bed position (300 vs. 90 s). Green arrows refer to strong focal uptake in the prostate, highly suspicious for prostate cancer, while the red arrow refers to a missed lesion due to extensive halo artefact occurrence at 90 s. Yellow arrows denote lesion locations on the T1-weighted MR image. “bl”: urinary bladder; “ur”: ureter
