  Purpose: To investigate the risk of false positive MRI and 18F-Fluorocholine (FCH) or 11Cacetate (AC) PET/ CT in prostate cancer patients with long term biochemical and clinical remission after curative radiation therapy (RT). Methods and Materials: Twenty patients underwent MRI studies including T2-weighted, diffusion weighted, dynamic contrast-enhanced, and spectroscopic imaging. Nine of these patients were selected to have FCH and 10 AC PET/CT studies. Results: MR spectroscopy suggested positive or equivocal results in 16/20 patients. However, the combined interpretation of all MRI sequences dropped the rate of suspicious or equivocal studies to 8/20. All but one patient underwent also PET/CT and early PET frames showed suspicious or equivocal local images in 15/19 patients (8/10 with AC, 7/9 with FCH). However, a com.. Read More»
