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.
