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

open access: yesThe 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

Radiosynthesis and Tumor MicroPET/CT Imaging of 18F-Fluoro­ethoxylerianin, an 18F-Labeled Erianin Analogue

open access: yesSynOpen, 2022
Erianin is an active constituent of Dendrobium candidum. In this work, 18F-fluoroethoxylerianin ([18F]FEE), a 18F-Labeled erianin analogue, was designed and synthesized to evaluate the properties of erianin and related analogues by in vivo PET imaging ...

Synthesis of Fluorine-18 Functionalized Nanoparticles for use as in vivo Molecular Imaging Agents [PDF]

open access: yes, 2008
Nanoparticles containing fluorine-18 were prepared from block copolymers made by ring opening metathesis polymerization (ROMP). Using the fast initiating ruthenium metathesis catalyst (H_2IMes)(pyr)_2(Cl)_2Ru=CHPh, low polydispersity amphiphilic block ...

Preclinical comparison of four [18F, natGa]rhPSMA-7 isomers: influence of the stereoconfiguration on pharmacokinetics

open access: yesEJNMMI Research, 2020
Introduction Radiohybrid (rh) ligands, a novel class of prostate-specific membrane antigen (PSMA)-targeted radiopharmaceuticals, can be labeled either with [18F]fluorine via isotopic exchange or with radiometals (such as [68Ga]Gallium, [177Lu]Lutetium ...

Synthesis, in vitro evaluation, and radiolabeling of fluorinated puromycin analogues: potential candidates for PET imaging of protein synthesis [PDF]

open access: yes, 2016
There is currently no ideal radiotracer for imaging protein synthesis rate (PSR) by positron emission tomography (PET). Existing fluorine-18 labelled amino acid-based radiotracers predominantly visualize amino acid transporter processes, and in many ...

In vivo imaging of pyrrole-imidazole polyamides with positron emission tomography [PDF]

open access: yes, 2008
The biodistribution profiles in mice of two pyrrole-imidazole polyamides were determined by PET. Pyrrole-imidazole polyamides are a class of small molecules that can be programmed to bind a broad repertoire of DNA sequences, disrupt transcription factor ...
