New PET imaging method may yield benefits over FDG for detecting certain cancers

German researchers have developed a PET imaging method that may raise the bar on diagnosing certain cancers. The method targets cancer-associated fibroblasts (CAFs), which have been linked to tumor growth and are present in over 90 percent of epithelial carcinomas such as pancreatic, colon and breast cancer. The team created a PET tracer based on a FAP-specific enzyme inhibitor (FAPI). Read more.
