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.
