Abstract

In this work, the feasibility of using T~2ρ~ weighting as an MR contrast mechanism is evaluated. Axial images of a human brain were acquired using a single‐slice spin‐lock T~2ρ~‐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~2ρ~‐weighted images was approximately 40% greater than that from T~2~‐weighted data. These preliminary data suggest that the novel contrast mechanism of T~2ρ~ can be used to yield high‐contrast T~2~‐like images. Magn Reson Med 52:1223–1227, 2004. © 2004 Wiley‐Liss, Inc.
