Automatic muscle and fat segmentation in the thigh from T1-Weighted MRI.

Purpose: To introduce and validate an automatic segmentation method for the discrimination of skeletal muscle (SM), and adipose tissue (AT) components (subcutaneous adipose tissue [SAT] and intermuscular adipose tissue [IMAT]) from T1-weighted (T1 -W) magnetic resonance imaging (MRI) images of the thigh.

Materials And Methods: Eighteen subjects underwent an MRI examination on a 1.5T Philips Achieva scanner.
