Spatial suppression of peripheral regions (outer volume suppression) is used in MR spectroscopic imaging to reduce contamination from strong lipid and water signals. The manual placement of outer volume suppression slices requires significant operator interaction, which is time consuming and introdu

✦ Synopsis
Abstract
An automatic technique for removal of extrameningeal tissues from MR images of human brain is described. The algorithm is based on the segmentation of images acquired with a fast dual‐echo pulse sequence, which incorporates both fluid attenuation and magnetization transfer contrast for superior brain/extrameningeal tissue contrast compared to conventional MR sequences. Evaluation of this technique using MR images of six volunteers indicates rapid and consistent removal of extrameningeal tissues.

## 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 con
