CT or PET or MRI scanner machine at hospital.
PSMA PET scans use radiotracers, which are radioactive molecules that bind specifically to PSMA on prostate cancer cells. When these radiotracers are introduced into the body, they “light up” on the scan, allowing for precise visualization of cancerous cells. Although there are various PSMA-based tracers available, there is no consensus on the optimal one. Different institutions may use different tracers, but the critical factor is ensuring the scan is performed, rather than focusing on which tracer is used.
One of the standout features of PSMA PET scans is their ability to detect prostate cancer at an incredibly small scale. They can identify micrometastatic disease as small as 2 mm, making them superior to traditional imaging methods such as CT, MRI, or bone scans. This level of precision is crucial for accurately determining the extent of the disease and guiding treatment decisions.
For those diagnosed with prostate cancer, PSMA PET scans are essential. They help determine the stage of the cancer, ensuring that no disease has metastasized beyond the prostate. This precision can prevent unnecessary treatments, such as surgery or radiation therapy, by providing a clear picture of the disease’s spread.
“PSMA PET is the single best method we have to precisely visualize prostate cancer in the body. It can pinpoint micrometastatic disease as small as 2 mm, offering unparalleled accuracy compared to conventional imaging.” — Tejas Suresh, MD, Medical Oncologist, Virginia Cancer Specialists
Despite their importance, insurance companies often deny coverage for PSMA PET scans. In such cases, your physician’s office will need to provide documentation to support the test’s necessity, including appeals, prior authorizations, and letters of medical necessity.
For patients with high-risk prostate cancer at the time of initial diagnosis, consulting a medical oncologist is crucial. A multi-disciplinary treatment plan tailored to the individual’s specific needs can be developed, enhancing the effectiveness of the overall treatment strategy.
PSMA PET scans are a vital tool in the fight against prostate cancer, offering unparalleled precision in detecting and staging the disease. If you or a loved one is facing a prostate cancer diagnosis, discussing the option of a PSMA PET scan with your urologist and advocate for its use if necessary.
