Image findings of cranial nerve pathology on [18F]-2- deoxy-D-glucose (FDG) positron emission tomography with computerized tomography (PET/CT): a pictorial essay. [PDF]
, 2015 This article aims to increase awareness about the utility of (18)F -FDG-PET/CT in the evaluation of cranial nerve (CN) pathology. We discuss the clinical implication of detecting perineural tumor spread, emphasize the primary and secondary (18)F -FDG-PET/

Improved detection of molecular markers of atherosclerotic plaques using sub-millimeter PET imaging [PDF]
, 2020 Since atherosclerotic plaques are small and sparse, their non-invasive detection via PET imaging requires both highly specific radiotracers as well as imaging systems with high sensitivity and resolution.

Physical Review, 1958 The atomic-beam magnetic resonance method has been used to measure the nuclear angular momentum of 68-minute gallium-68. It is found that I = 1. (auth) The spins of three radioactive silver isotopes, Ag/sup 105/(T/sub 1/2/ = 40 days, I = 1/2), Ag/sup 106/(T/sub 1/2/ = 8.3 days, I and Ag/sup 110m/(T/sub 1/2/ = 253 days, I = 6), have been measured by ...

Comparative gallium-68 labeling of TRAP-, NOTA-, and DOTA-peptides: practical consequences for the future of gallium-68-PET [PDF]
EJNMMI Research, 2012 Currently, 68Ga-labeled 1,4,7,10-tetraazacyclododecane-tetraacetic acid (DOTA)-peptides are the most widely used class of 68Ga radiotracers for PET, although DOTA is not optimal for 68Ga complexation. More recently, 1,4,7-triazacyclononane-triacetic acid (NOTA) and particularly triazacyclononane-phosphinate (TRAP) chelators have been shown to possess ...
