Automated radiosynthesis of [(18)F]FMPEP-d(2) for cannabinoid receptor PET imaging.

The cannabinoid subtype 1 receptor (CB1R) is highly expressed in the central nervous system and abnormalities in regional CB1R density are associated with neurodegenerative disorders. The PET tracer [[18] F]FMPEP-d[2] is an inverse CB1R agonist which ...

Marriage of radiotracers and total-body PET/CT rapid imaging system: current status and clinical advances.

Radiotracers and medical imaging equipment are the two main keys to molecular imaging. While radiotracers are of great interest to research and industry, medical imaging equipment technology is blossoming everywhere. Total-body PET/CT (TB-PET/CT) has ...

Diagnostic efficacy of C-X-C motif chemokine receptor 4-directed PET/CT in newly diagnosed head and neck squamous cell carcinoma - a head-to-head comparison with [(18)F]FDG.

Background: The aim of this study was to determine the read-out capabilities of the novel C-X-C motif chemokine receptor 4 (CXCR4)-targeting radiotracer [[68] Ga]Ga-PentixaFor compared to the reference radiotracer [[18] F]FDG in untreated individuals ...

Visualization of ferroptosis in brain diseases and ferroptosis-inducing nanomedicine for glioma.

A remarkable body of new data establishes that many degenerative brain diseases and some acute injury situations in the brain may be associated with ferroptosis. In recent years, ferroptosis has also attracted great interest in the cancer research community, ...
