PSMA PET/CT
In simple words
Prostate cancer cells carry a distinctive protein on their surface called PSMA. We use a molecule that fits that protein like a key in a lock, tagged with gallium-68. Wherever prostate cancer cells are hiding — even a single small lymph node — the tracer sticks to them and lights up on the scan.
Questions this scan answers
- Has my prostate cancer spread to bones or lymph nodes?
- My PSA is rising after surgery or radiation — where is the disease?
- Am I suitable for targeted radioligand therapy?
The Prismaa difference
PSMA lesions can be tiny. Digital detectors with 300-picosecond time-of-flight place each signal far more precisely, which is exactly what you need when the finding that changes your treatment is a 5 mm node next to a blood vessel.
Usually recommended for
- Newly diagnosed intermediate- or high-risk prostate cancer
- Rising PSA after prostatectomy or radiotherapy (biochemical recurrence)
- Before deciding between surgery, radiation and hormone therapy
- Screening suitability for Lu-177 PSMA therapy
How to prepare
- No fasting needed — eat normally.
- Drink water and empty your bladder just before scanning; the tracer is excreted in urine and a full bladder can hide nearby disease.
- Carry your PSA trend, biopsy or Gleason report, and any earlier scans.
- Tell us if you are on hormone therapy (ADT) and when it was started.
