PET scans better than MR at detecting more aggressive prostate cancer: study

August 21, 2015

Researchers have discovered that PET imaging with a specific biomarker can detect a fast-growing primary prostate cancer and is better able to differentiate it from benign prostate lesions, a process that they hope could eventually replace the traditional ultrasound-guided 12-core biopsy. 

The study, published in the July 2015 issue of The Journal of Nuclear Medicine, looked at 13 patients with primary prostate cancer who underwent PET imaging with F-18 DCFBC PET, using a low-molecular weight radiotracer that targets the prostate-specific membrane antigen (PSMA), which is associated with a more aggressive form of the disease. A dozen of those patients also had a pelvic prostate MR scan.
