Rapid T(1) mapping using multislice echo planar imaging.

Determination of neurological pathology in white matter disease can be made in a semiquantitative way from T(1)- or T(2)-weighted images. A higher level of quantification based on measured T(1) or T(2) values has been either limited to specific regions of interest or to low-resolution maps. Higher-resolution T(1) maps have proved difficult to obtain due to the excessively long scan times required using conventional techniques. In this study, clinically acceptable images are obtained by using single-shot echo planar imaging (EPI) with an acquisition scheme that maximizes signal-to-noise while minimizing the scan time.
