Suspicious lesion within the prostate. (A) Axial T2-weighted (T2W) magnetic resonance image (MRI). (B) b2000 diffusion-weighted (DW) MRI. (C) Coronal T2W MRI. (D) Dynamic contrast enhanced (DCE) MRI image shows a right midbase transition zone lesion suspicious for recurrent prostate cancer. The lesion shows focal intense 18F-DCFPyL uptake on axial (E) and coronal (F) fused positron emission tomography/computed tomography images (arrows).

Suspicious lesion within the right penile bulb. (A) 18F-DCFPyL positron emission tomography (PET) and (B) fused PET/computed tomography images show focal intense uptake within the right penile bulb, which is confirmed by (C) axial T2W magnetic resonance imaging (MRI) (arrows). In (B), note the presence of brachytherapy seeds in proximity to the penile bulb lesion. The right penile bulb lesion (arrows) shows diffusion restriction at b2000 diffusion-weighted MRI (D) and focal early enhancement at dynamic contrast-enhanced MRI (E). (F) Additionally, this lesion shows distinct enhancement on computed tomography (arrow).

Radiation treatment plan and imaging. (A) Axial and (B) sagittal images of a radiation treatment plan delivering 40 Gy in 5 fractions to the recurrent tumor within the prostate (gross tumor volume segmented orange and planning target volume segmented purple for the prostate tumor; gross tumor volume segmented orange and planning target volume segmented green for the penile bulb lesion). Dose colorwash is overlayed, showing a lower prescription dose to the penile bulb lesion. (C, D) Brachytherapy seed groups were contoured and used as fiducial markers.
