recommendations! Published in 2022 at "Journal of Magnetic Resonance Imaging"

DOI: 10.1002/jmri.28239

Abstract: Amide proton transfer (APT) imaging is a chemical exchange saturation transfer (CEST) technique offering potential clinical applications such as diagnosis, characterization, and treatment planning and monitoring in glioma patients. While APT‐CEST has demonstrated high potential,… read more here.

DOI: 10.1002/mrm.28021

Abstract: Chemical exchange saturation transfer (CEST) signals at 3 ppm acquired with high irradiation powers, termed GluCEST, have been suggested as an indicator of glutamate in neural systems. However, amines in proteins may also contribute to… read more here.
