In this work we propose a flexible and quantitative
method for sodium (23Na) imaging to determine the total
sodium concentration (TSC) and characterize the signal
decay, which is related to bound and unbound 23Na. A
(compressed sensing accelerated) 3D FID spectroscopic
imaging sequence is used to maximize the ratio between
sampling time and total acquisition time to optimize the
SNR, obtain a high temporal resolution and acquire 23Na
images in both a calibration phantom and in the knee of
a healthy volunteer.
