Biodistribution and radiation dosimetry of the novel hypoxia PET probe [18F]DiFA and comparison with [18F]FMISO

EJNMMI Research, 2019
Background To facilitate hypoxia imaging in a clinical setting, we developed 1-(2,2-dihydroxymethyl-3-[18F]-fluoropropyl)-2-nitroimidazole ([18F]DiFA) as a new tracer that targets tumor hypoxia with its lower lipophilicity and efficient radiosynthesis ...

[18F]Fluoride recovery via gaseous [18F]HF

, 2011
Acidification of target water with H2SO4 in a specially constructed glassy carbon/polyethylene apparatus allowed for recovery of up to 82% of [18F]fluoride as [18F]HF gas.

Mac‐2 Binding Protein Glycosylation Isomer (M2BPGi)–Based Risk Stratification Refined by Tumor Metabolic Activity in Hepatocellular Carcinoma

Annals of Gastroenterological Surgery, EarlyView.
M2BPGi reflects background liver fibrosis and hepatic functional impairment. PET SUVmax reflects tumor metabolic aggressiveness. Their combination identifies a dual‐high subgroup with the poorest recurrence‐free and overall survival. ABSTRACT Aim To evaluate the prognostic significance of preoperative Mac‐2 binding protein glycosylation isomer (M2BPGi)

The diagnostic performance of 18F-FAMT PET and 18F-FDG PET for malignancy detection: a meta-analysis

BMC Medical Imaging, 2017
Background This meta-analysis aims to compare the diagnostic performance of l-3-18F-α-methyl tyrosine (18F-FAMT) positron emission tomography (PET) and 2-deoxy-2-[18F]fluoro-d-glucose (18F-FDG) PET for malignancy detection.

[18F]fluorination/decarbonylation: New route to aryl [18F]fluorides [PDF]

, 1991
A new route to aryl [18F]fluorides without electron withdrawing ring substituents has been developed. [18F]Fluorobenzaldehydes, prepared from no-carrier-added (NCA) [18F]fluoride using nucleophilic aromatic substitution of fluoro or nitro groups, were ...

Centrum Semiovale Perivascular Spaces Predict First Hemorrhagic Lesion in Asymptomatic Amyloid‐Positive Individuals

Annals of Neurology, EarlyView.
Objective Identification of cerebral amyloid angiopathy (CAA) before its hemorrhagic manifestations remains limited. We aimed to determine whether severe enlarged perivascular spaces in the centrum semiovale (EPVS‐CSO) identify a prehemorrhagic stage of sporadic CAA by predicting the first appearance of CAA‐related hemorrhagic lesions or incident ...

In vivo imaging of cellular proliferation in colorectal cancer using positron emission tomography [PDF]

, 2003
Background and aims: Positron emission tomography (PET) using 18F labelled 2-fluoro-2-deoxy-D-glucose (18FDG) is an established imaging tool, although the recent development of a biologically stable thymidine analogue [18F] 3'-deoxy-3-fluorothymidine ...

The integrated Lei‐CNS PBPK‐PD model effectively predicts clozapine brain disposition and D2 receptor occupancy in humans

British Journal of Clinical Pharmacology, EarlyView.
Aim Clozapine, used for treatment‐resistant schizophrenia, has a narrow therapeutic window and highly variable plasma pharmacokinetics (PK), necessitating careful monitoring. Direct measurement of unbound brain PK in humans is unethical. To develop a physiologically based pharmacokinetic–pharmacodynamic (PBPK‐PD) model to predict clozapine brain ...
