Ga-68 PSMA PET CT scan | Helios Clinic Berlin-Buch, Germany

The Gallium-68 Prostate-Specific Membrane Antigen Positron Emission Tomography-Computed Tomography (Ga-68 PSMA PET-CT) scan is a cutting-edge imaging technique designed to detect and evaluate prostate cancer with exceptional precision. The process typically lasts around 1 to 2 hours. This diagnostic tool relies on a radiotracer, Ga-68 PSMA, which targets the PSMA protein often overexpressed in prostate cancer cells. During the Ga-68 PSMA PET-CT scan, a small amount of the radiotracer is injected into the patient's bloodstream. The Ga-68 PSMA then travels to prostate cells, binding to the PSMA receptors. This allows for the visualization of prostate cancer lesions at a molecular level. The combination of PET and CT imaging provides both functional and anatomical information, enabling comprehensive assessments of the extent and location of prostate cancer. Candidates for Ga-68 PSMA scans typically include individuals with a confirmed diagnosis of prostate cancer, especially those with rising prostate-specific antigen (PSA) levels despite prior treatment or with suspected metastatic disease. It is precious for identifying small or distant lesions that might not be detected through conventional imaging methods. The scan aids in treatment planning, monitoring disease progression, and assessing response to therapy. The Ga-68 PSMA PET-CT scan represents a significant advancement in prostate cancer imaging, offering clinicians valuable insights for personalized treatment strategies and improved patient outcomes. In addition, such a scan is a routine procedure required before Lutetium 177 PSMA therapy. The process involves several key steps:Radiotracer Injection: A small amount of the Ga-68 PSMA radiotracer is injected into the patient's vein. The radiotracer circulates through the bloodstream and accumulates in prostate cancer cells. Uptake Period: After injection, there is a waiting period for the radiotracer to be absorbed by the prostate cancer cells. This allows for optimal imaging of the targeted areas. Imaging Session: The patient undergoes a combined PET-CT scan, capturing functional (PET) and anatomical (CT) images. The patient remains on a scanning table as the imaging machine moves around them. Preparation for the scan involves fasting (patients may be required to fast for a few hours before the scan to enhance radiotracer uptake) and medication review (it's crucial to inform the healthcare team about medications and any recent medical procedures, as they can influence the scan results). As a result, the patient will receive digital files (DICOM), written interpretation, and further recommendations from your nuclear medicine expert.
