Interobserver and intraobserver agreement in PET/CT with [F]DCFPyL according to TNM molecular and PSMA-RADS 2.0 criteria.

Purpose: The aim of this study was to determine the agreement between three observers with different levels of experience using the PSMA-RADS 2.0 criteria and the miTNM system for the interpretation of PET-PSMA with [F]DCFPyL in males with prostate cancer.

Materials And Methods: PET-PSMA images from 114 prostate cancer patients were blindly reported twice by three different observers at intervals of 8 weeks.

Diagnostic utility of PET/CT with F-DOPA and F-FDG in persistent or recurrent medullary thyroid carcinoma: the importance of calcitonin and carcinoembryonic antigen cutoff.

Purpose: This study sought to evaluate and compare the utility of 18-F-fluorodihydroxyphenylalanine (F-DOPA) and 18-F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) for identification of lesions in patients with recurrent medullary thyroid carcinoma (MTC). In addition, we analyzed the correlation between the calcitonin (Ct), carcinoembryonic antigen (CEA) levels, each doubling time (DT), and PET positivity. We evaluated the reliability of the 150 pg/mL Ct cutoff set by the American Thyroid Association guidelines for further imaging (including F-DOPA PET/CT).
