Overview

Positron Emission Tomography - Computed Tomography (PET-CT) and Prostate-Specific Membrane Antigen PET (PSMA PET) are the two cutting-edge imaging tests doctors use to diagnose, detect, and stage urologic cancers, especially prostate cancer. These tests help healthcare professionals determine whether cancer has spread (metastasized) beyond its origin, guiding treatment decisions and improving patient outcomes.

PSMA PET is a specialized molecular imaging scan that targets PSMA, a protein highly expressed in prostate cancer cells. Compared to conventional PET-CT scans, PSMA PET offers higher sensitivity and specificity, making it particularly valuable for detecting even small metastatic lesions.

Why is PET-CT / PSMA PET Performed?

• To detect metastatic spread of cancers such as prostate, bladder, kidney, or testicular cancer.
• To identify recurrence of cancer after treatment.
• To evaluate the extent and aggressiveness of the disease.
• To guide treatment planning, including surgery, radiotherapy, or systemic therapies.
• To monitor the response to ongoing treatment.

Before the Scan

• Patients may follow the instructions to fast for a few hours before the test.
• Hydration is usually encouraged to improve tracer distribution and minimize radiation exposure.
• In the case of PSMA PET, a small amount of a radioactive tracer (PSMA ligand bound to Gallium-68 or F-18) is injected intravenously.
• Before the test, patients should inform their doctor about allergies, medications, kidney function issues, or pregnancy.

During the Scan

• After tracer injection, a waiting period (typically 45–90 minutes) allows the substance to circulate and bind to cancer cells.
• The doctors ask the patient to lie on a scanning table that moves slowly through the PET-CT machine.
• The PET scan detects areas where cancer cells take up the tracer, while the CT scan provides detailed anatomical images.
• The combined images help pinpoint the exact tumor location and spread.

After the Scan

• Patients can usually resume normal activities immediately.
• Drinking plenty of fluids helps flush the radioactive tracer from the body.
• Nuclear medicine specialists and urologic oncologists interpret the results to guide treatment decisions.

Benefits

• High accuracy in detecting small or hidden metastases.
• Improved cancer staging compared to conventional imaging.
• Early detection of recurrence in prostate and other urologic cancers.
• Helps in personalized treatment planning for optimal outcomes.

Risks

• Exposure to a small amount of radiation is generally considered safe.
• Rare risk of allergic reaction to the tracer.
• Not appropriate or suitable for pregnant women due to radiation exposure.

FAQs on PET-CT / PSMA PET for Metastasis Detection

How is PSMA PET different from a regular PET-CT?

PSMA PET uses a tracer that specifically binds to the PSMA protein on prostate cancer cells, making it more sensitive and accurate than conventional PET scans for prostate cancer detection.

How long does the scan take?

The procedure usually takes 2–3 hours, including preparation, tracer uptake time, and scan.

Will I feel pain during the scan?

No, the procedure is painless except for a small needle prick during tracer injection.

How soon can I get results?

Depending on hospital reporting protocols, preliminary results are often available within 24–48 hours.

Can PET-CT detect all types of urologic cancers?

While PET-CT and PSMA PET are beneficial for prostate cancer, they are also valuable for staging bladder, kidney, and testicular cancers.
