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: 10.1007/s00259-019-04509-y
Abstract: 18F-FDopa PET imaging of gliomas is routinely interpreted with standardized uptake value (SUV)-derived indices. This study aimed to determine the added value of dynamic 18F-FDopa PET parameters for predicting the molecular features of newly diagnosed… read more here.

DOI: 10.1097/rlu.0000000000001496
Abstract: Purpose The use of 18Fluorine-labeled dihydroxy-phenyl-alanine (18F-FDOPA) PET/CT in patients with hypoglycemia suspected to be caused by pancreatic disease can be helpful to localize the source of excess insulin production. In this setting, carbidopa pretreatment… read more here.

DOI: 10.1097/rlu.0000000000002959
Abstract: Amino acid PET, including F-FDOPA, is recommended for initial characterization, delineation of tumor extent, and follow-up of gliomas because of its high diagnostic performances. F-FDOPA accumulates inside tumor cells via the L-type amino acid transporter… read more here.

DOI: 10.1097/rlu.0000000000004137
Abstract: ABSTRACT Orbital foci of increased uptake are sometimes visualized on 18F-FDOPA PET/CT, but the literature remains poor as to their nature. The orbit is indeed a rare site of metastatic involvement. Given this low probability… read more here.

DOI: 10.1097/rlu.0000000000004664
Abstract: ABSTRACT A 30-year-old man with pheochromocytoma was hospitalized for hemoptysis without inducement. CT revealed a mass in the left lung, and biopsy pathology under the bronchoscope suggested that it was a pheochromocytoma metastasis. To further… read more here.

Dynamic 18F-FDopa PET Imaging for Newly Diagnosed Gliomas: Is a Semiquantitative Model Sufficient?
Sign Up to like & getrecommendations! Published in 2021 at "Frontiers in Oncology"
DOI: 10.3389/fonc.2021.735257
Abstract: Purpose Dynamic amino acid positron emission tomography (PET) has become essential in neuro-oncology, most notably for its prognostic value in the noninvasive prediction of isocitrate dehydrogenase (IDH) mutations in newly diagnosed gliomas. The 6-[18F]fluoro-l-DOPA (18F-FDOPA)… read more here.
