APT imaging can be used to obtain tissue pH information.
In this abstract, the quantitative measurements of APT
signals and tissue pH in the acute ischemic stroke in
rats were performed using extrapolated semi-solid
magnetization transfer reference (EMR) signals. Our EMR
approach may be helpful for more accurate APT pH
quantification, and useful to understand and identify
the characteristics of the ischemic stroke tissue.
