摘要：

In this work, the feasibility of using T-2rho weighting as an MR contrast mechanism is evaluated. Axial images of a human brain were acquired using a single-slice spin-lock T-2rho-weighted pulse sequence and compared to analogous T-2-weighted images of the same slice. The contrast between white matter and gray matter in T-2rho-weighted images was approximately 40% greater than that from T-2-weighted data. These preliminary data suggest that the novel contrast mechanism of T-2rho can be used to yield high-contrast T-2-like images. (C) 2004 Wiley-Liss, Inc.
