Purpose: To assess whether the addition of data from multiparametric pelvic (mpMR) and whole body MR (wbMR) to the interpretation of 18F-fluoromethylcholine (FCH) or 68Ga-HBED-CC PSMA-11 (PSMA) PET/CT (=PET) improves the detection of local tumor recurrence, or nodal and distant metastases in patients following radical prostatectomy with biochemical failure. Methods: The current analysis was performed as part of a prospective, multicenter trial on FCH / PSMA PET, mpMR and wbMR. Eligible men had elevated PSA (>0.2 ng/ml) and high-risk features (Gleason score >7, PSA doubling time 1.0 ng/ml) with negative/ equivocal conventional imaging. PET was interpreted with mp&wbMR in consensus by 2 radiol..View full abstract
We acknowledge the invaluable guidance and tireless support of Sam Gledhill of the Movember Foundation. Further thanks are given to the Society of Nuclear Medicine and Molecular Imaging team headed by Bonnie Clark for their role in the management of the imaging and data collection. We also acknowledge the support of local clinical trials teams in bringing together this project.
