Isotopic Radiolabeling of the Antiretroviral Drug [¹⁸F]Dolutegravir for Pharmacokinetic PET Imaging

Pharmaceuticals, 2022
Deciphering the drug/virus/host interactions at infected cell reservoirs is a key leading to HIV-1 remission for which positron emission tomography (PET) imaging using radiolabeled antiretroviral (ARV) drugs is a powerful asset. Dolutegravir (DTG) is one

Fully Automated, High-Dose Radiosynthesis of [¹⁸F]PARPi

Pharmaceuticals, 2022
[18F]PARPi is currently undergoing clinical trials as a PET tracer for many applications. However, only manual radiosynthesis was reported; this has several drawbacks, including an increased risk of contamination from the operator, and the need to limit ...

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.

PET Imaging of Fructose Metabolism in a Rodent Model of Neuroinflammation with 6-[¹⁸F]fluoro-6-deoxy-D-fructose

Molecules, 2022
Fluorine-18 labeled 6-fluoro-6-deoxy-D-fructose (6-[18F]FDF) targets the fructose-preferred facilitative hexose transporter GLUT5, which is expressed predominantly in brain microglia and activated in response to inflammatory stimuli.

Importance of fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in detection of post-thyroidectomy recurrence in differentiated thyroid cancer with negative radio-isotope iodine scan, yet, elevated serum thyroglobulin level

The Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Thyroid cancer considered the 6th common cancer in female and represents approximately 1% of all cancers. Thyroid cancer is generally characterized by good prognosis, long term survival and low aggressiveness. Its prognosis is related to tumor
