WebDec 24, 2024 · Dynamic glucose enhanced (DGE) MRI has shown potential for imaging glucose delivery and blood–brain barrier permeability at fields of 7T and higher. Here, we evaluated issues involved with translating d -glucose weighted chemical exchange saturation transfer (glucoCEST) experiments to the clinical field strength of 3T. WebThis proof-of-concept study looked at the feasibility of using a thiol–water proton exchange (i.e., CEST) MRI contrast to detect in vivo hepatic N-acetylcysteine (NAC) uptake. The feasibility of detecting NAC-induced glutathione (GSH) biosynthesis using CEST MRI was also investigated. The detectability of the GSH amide and NAC thiol CEST effect at …
WebFIG. 1. Timing of the dynamic glucose enhanced (DGE) and dynamic contrast enhanced (DCE) acquisition. D-glucose (2.8 M) was injected at 2.5 mL/s while Gd-DTPA (100 mM) was injected at 10 mL/s. DCE images were acquired 1 h postglucose injection. Both the glucose and Gd-DTPA bolus were given without stopping the scan or re-positioning the … WebDec 1, 2015 · Recent animal studies have shown that d-glucose is a potential biodegradable magnetic resonance imaging (MRI) contrast agent for imaging glucose uptake in tumors.We show herein the first translation of that use of d-glucose to human studies.Chemical exchange saturation transfer (CEST) MRI at a single frequency offset …
