Oncology: PET Diagnostics and Radioligand Therapy (RLT) for Cancer
Radioactive medicines used in oncology are designed to target tumor cells and carry radioactive elements. Some, like 68Ga and 99ᵐTc, are used for imaging to locate cancer in the body. Others, like 177Lu and 225Ac, are used for radioligand therapy (RLT), delivering radiation directly to tumors. Together, they enable both diagnosis and treatment through a single targeted approach.
Neurology: PET Ligands for Brain Imaging
In the brain, radioactive medicines help visualize changes linked to neurological diseases. These drugs are built to cross the blood–brain barrier and bind to specific proteins involved in conditions like Alzheimer’s or Parkinson’s disease. Once injected, they emit signals that PET/CT scanners can detect, creating images of brain function, metabolism, or disease sites. This non-invasive method enables early detection and monitoring, and researchers are working to make brain imaging even more accurate, long-lasting, and safe.
