PSMA PET-CT Scan

Typical Clinical Scenarios

• Rising PSA after radical prostatectomy or radiation (biochemical recurrence).
• High-risk, newly diagnosed prostate cancer when staging or treatment planning.
• Before focal therapy or salvage treatments to ensure cancer is localized.
• Monitoring metastatic disease response in select cases.

Benefits Over Conventional Imaging

• Detects disease at PSA levels as low as 0.2–0.5 ng/mL.
• Improved localization of nodal or bone metastases.
• Reduces unnecessary treatments by clarifying the true extent of disease.
• Helps us tailor surgery, radiation fields, systemic therapy, or active surveillance.

Tracer Injection

You receive an intravenous injection of an FDA-approved PSMA-targeted radiotracer (commonly Ga-68 PSMA-11, F-18 Pylarify, or F-18 PSMA DCFPyL). The tracer travels through your bloodstream and attaches to PSMA receptors on prostate cancer cells.

Integrated Imaging

After a short uptake period (about 45–60 minutes), you lie on the imaging table. The scanner first captures CT images for anatomy, then PET detects tracer emissions. The merged data creates high-resolution, color-coded images for our radiologists and urologists to review together.

Before the Scan

• Stay well hydrated the day prior and the morning of your visit.
• Eat a light, low-carbohydrate meal 4 hours before arrival unless instructed otherwise.
• Bring a list of current medications, prior imaging, and treatment history.
• Inform us if you have diabetes, kidney disease, or if there is a chance you are pregnant.

Day-of Logistics

• Plan to spend approximately 2–2.5 hours at the imaging center.
• Wear comfortable clothing without metal zippers or snaps.
• Continue drinking water — it speeds tracer clearance and improves image quality.
• No sedation is required; you can drive yourself home afterward.

During the Visit

1. Check in, review your medical history, and place an IV line.
2. Receive the tracer injection and relax in a private uptake room.
3. Use the restroom just before imaging to empty your bladder.
4. Lie still on the scanner table for about 20–30 minutes while the PET-CT acquires images.

After Your Scan

• Drink extra water throughout the day to flush out the tracer.
• Resume normal activities immediately — there are no activity restrictions.
• Avoid close, prolonged contact with pregnant individuals or infants for 6 hours as a precaution.
• Our radiologists interpret the study the same day and send results to your urologist.

Multidisciplinary Review

Advanced Urology physicians review the images with subspecialized radiologists. We correlate PSMA uptake with your PSA trend, biopsy findings, and prior imaging to decide on next steps.

• Localized Uptake May support focal therapy, salvage radiation, or targeted lymph node dissection.
• Regional Disease Helps determine whether pelvic lymph nodes require treatment.
• Distant Metastases Guides systemic therapy, clinical trials, or advanced radiation strategies.

Limitations to Know

• Inflammation or benign lesions rarely take up tracer, which can mimic disease.
• Very small foci (<4 mm) may still be below the resolution of PET.
• Insurance coverage varies; we obtain prior authorization and review any out-of-pocket costs before scheduling.

Is PSMA PET-CT safe?

Yes. The tracer delivers a low dose of radiation, comparable to or lower than many diagnostic CT scans. Side effects are rare and typically limited to brief discomfort at the IV site.

Will my insurance cover it?

Most commercial insurers and Medicare cover PSMA PET-CT when criteria are met. Our team manages prior authorization and communicates any expected costs before you commit.

How quickly do I get results?

Reports are usually available within 24 hours. We schedule a follow-up visit or telehealth call to explain the findings, share the images, and finalize your treatment plan.

What if the scan is negative?

A negative PSMA PET-CT is reassuring. We may repeat imaging later if PSA continues to rise, and we will discuss alternative diagnostics or clinical trial options tailored to your case.
