Prostate-Specific Membrane Antigen (PSMA) PET Imaging for Prostate Cancer: A New Way to Diagnose and Treat
Prostate cancer remains a significant health challenge for men, particularly in the U.S., where it ranks as the third most common cancer, with over 190,000 new cases and approximately33,000 deaths reported in 2020. Traditional imaging methods such as CT scans, MRIs, and bone scans have been instrumental in diagnosis and treatment but often fall short in detecting small or dispersed cancerous areas. At SDMI, we are excited to offer the cutting-edge PSMA PET imaging technology, which represents a major advancement in prostate cancer care.
Why SDMI Chooses PSMA PET Imaging
Traditional imaging techniques like CT and MRI are valuable but can sometimes miss critical details, particularly when cancer has spread. Traditional PET scans that utilize the standard FDG agent has limitations in detecting early-stage prostate cancer. This creates a significant gap for newly diagnosed patients or those without a recurrence. SDMI addresses this need with the innovative PSMA PET imaging, which targets a specific protein found on prostate cancer cells.
How PSMA PET Works - During a PSMA PET scan, the PSMA specific radioactive tracer is injected into the patient’s bloodstream. The tracer attaches to PSMA proteins on cancer cells. The PET scan then detects where the tracer is concentrated, which helps doctors find and map out cancerous areas more accurately.
Why PSMA PET is Better - PSMA PET imaging is more detailed and accurate compared to older methods. For example, traditional PET scan synthetic radioactive amino acids do not pinpoint the PSMA specific protein. The PSMA tracer provides a clearer picture of cancer spots, including in the pelvis and bones, which helps doctors plan better treatments.
In studies, PSMA PET has found more cancer spots than older methods in patients who had surgery and then saw their cancer return. This helps doctors create more effective treatment plans.
When PSMA PET is Useful - PSMA PET is especially useful for two groups:
- Men newly diagnosed with prostate cancer who might have cancer that’s spread.
- Men who have been treated for prostate cancer before but now have rising PSA levels, indicating the cancer might be back.
Improving Treatment with PSMA PET - Besides diagnosing, PSMA PET helps in planning and monitoring treatment. It provides detailed info about where cancer is located, guiding doctors in choosing the best treatment, like surgery or radiation. PSMA PET can also be combined with other scans, like CT or MRI, for a fuller picture of the cancer’s spread.
The Procedure: What to Expect - Getting a PSMA PET scan is straightforward. After the tracer is injected, it takes about an hour to circulate and bind to cancer cells. Then, the PET scan itself takes around 30minutes. The whole process usually takes about two hours.

The Future of PSMA PET Imaging - PSMA PET imaging is becoming more recognized for its effectiveness and is expected to become even more common. Ongoing research aims to make this technology even better and explore new treatments that use PSMA targeting. This means doctors will have more tools to provide personalized care for men with prostate cancer.
Conclusion
Prostate cancer is a serious issue, but new imaging technologies like PSMA PET are changing how it’s diagnosed and treated. If you or someone you know has prostate cancer, it’s important to discuss all available options with a healthcare provider. PSMA PET is a promising development that could lead to better outcomes for patients.
