Brief summary
This study will use high field MRI (3 Tesla), PET and biomarker to follow prostate cancers and determine if these tests can detect cancers that become aggressive.
Detailed description
This study may lead to the identification of additional investigations that can monitor for signs of disease progression in active surveillance protocols. This can directly benefit patients by providing them with greater confidence that their disease is being accurately monitored. In addition, this study may be beneficial to the general management of prostate cancers by adding to our knowledge of these investigations characterizing prostate cancers.
