Equivocal uptake in soft-tissue lesion typical of prostate cancer lesion on PSMA-targeted positron emission tomography (PET)/computed tomography (CT). 68Ga-PSMA-11 PET/CT for restaging in a 73-year-old man with a history of a prostate cancer. Whole-body maximum intensity projection image showing absence of clearly pathologic radiotracer uptake (A). Axial low-dose CT (B), contrast-enhanced CT (C), PET (D), and fused PET/CT (E) showing an iliac lymph node typical of a prostate cancer lesion on anatomic imaging, but with equivocal uptake (red arrows), consistent with a PSMA-RADS-3A lesion.
