Navigating PSMA PET in Advanced Prostate Cancer: A Case-Based Approach

Molecular imaging has displaced conventional CT and bone scans as the first-line staging tool in prostate cancer, but a radiation oncologist and a urologist explain where conventional imaging still holds value.

Radiotracer choice, cyclotron versus generator supply chains, and shifting reimbursement policy all shape which patients can access PSMA PET, according to two physicians who built imaging capacity directly into their practices.

An indeterminate bone lesion forces clinicians to weigh pretest probability, tracer type, and biopsy risk before committing to a diagnosis, with serial scanning often settling the question over time.

Physiologic PSMA uptake in ganglia, ureters, and other normal structures can mimic disease, and the panel walks through the anatomic pitfalls that most often mislead inexperienced readers.

Adoption of PSMA PET still varies by practice setting, and the panel discusses how visualized disease reshapes conversations with patients accustomed to tracking PSA values alone.

A rising PSA after treatment discontinuation prompts a PSMA PET that reveals a solitary rib lesion, testing how much confidence clinicians place in a single indeterminate finding.
