PET/CT Scans More Sensitive Than CT and Bone Scans For Detecting Metastatic Prostate Cancer

According to an article in the Journal of Nuclear Medicine, researchers compared a PET/CT scan using the radiotracer F-18 DCFBC to conventional imaging modalities — an expanded Tc-99m-methylene diphosphonate (MDP) bone scan and contrast-enhanced CT of the chest, abdomen and pelvis — to detect prostate-specific membrane antigen (PSMA), which is associated with prostate cancer metastases. In a study of 17 men the researchers found that the F-18 DCFBC PET scans were able to detect a larger number of prostate cancer lesions than the other imaging modalities. The researchers found 592 positive lesions compared to 520 identified by the other methods. [...]
