DOI: 10.1007/s00259-017-3833-y
Abstract: Introduction18F-FDOPA illustrates the properties of uptake and storage of catecholamines in pheochromocytomas (PHEOs). Until now, the relationship between 18F-FDOPA quantitative parameters and a PHEO secretory profile has not been specifically evaluated.Materials and methodsFifty-six patients (56%… read more here.

DOI: 10.1093/neuonc/noae165.0110
Abstract: Malignant peripheral nerve sheath tumors (MPNST) are aggressive soft tissue sarcomas that frequently arise from benign plexiform neurofibromas (PN). Approximately half of MPNST are associated with Neurofibromatosis type 1 (NF1). Despite partial elucidation of the… read more here.
