MR techniques, such as accurate mapping of the longitudinal relaxation time
and water content, have become more important in neurological research. The
current T1 mapping methods are generally lengthy and not adequate in a
clinical environment. Also, further acquisitions are usually required to
obtain the brain tissue water content. Several factors, including RF field
inhomogeneities and low SNR impair the accuracy of these methods. In this
study, we present a modified two-acquisition SPGR method for simultaneous B1,
T1, and M0 mapping with a 1-mm isotropic spatial resolution that covers the
entire human brain in a clinically acceptable time.
