68Ga-PSMA / 18F-PSMA

PSMA PET/CT

The gold standard for prostate cancer — finds disease that bone scans and CT miss.

PSMA PET/CT

68Ga-PSMA / 18F-PSMA≈ 15 min on the scannerAdvanced molecular study

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.

We are happy to discuss the request with your treating doctor before you commit to an appointment.

More about this scan

PSMA — prostate-specific membrane antigen — is expressed on the surface of the great majority of prostate cancer cells, and expression tends to rise as the disease becomes more aggressive. That makes it an almost ideal imaging target, and PSMA PET/CT has now replaced the CT-plus-bone-scan combination in international guidelines for staging higher-risk disease.

The other half of the story is therapy. The same PSMA molecule can carry a therapeutic isotope instead of an imaging one. A diagnostic PSMA PET/CT is therefore also the gatekeeper scan that shows whether a patient's disease would take up Lu-177 PSMA therapy — a treat-what-you-see approach known as theranostics.

Common questions

How is this better than a bone scan?
A bone scan only shows the bone's reaction to a tumour, and only in bone. PSMA PET/CT sees the cancer cells themselves, in bone and in soft tissue and lymph nodes, and it does so at much lower PSA levels. It routinely finds disease at PSA values where conventional imaging is still completely normal.
My PSA is only 0.3. Is a scan worth doing?
Often yes. PSMA PET/CT has a meaningful detection rate even below PSA 0.5 ng/mL, which is precisely the window where finding a single recurrence site can mean curative targeted radiotherapy instead of lifelong hormone therapy. Your urologist or oncologist will weigh this with you.
