Purpose
Acquisition of high‐resolution Z‐spectra for CEST or magnetization transfer contrast (MTC) MRI requires excessive scan times. Ultrafast Z‐spectroscopy (UFZ) has been proposed to address this; however, the quality of in vivo UFZ spectra has been insufficient. Here, we present a simple approach to improve this.
Theory and Methods
UFZ imaging acquires full Z‐spectra by encoding the spectral...
