Use of magnetic resonance in body composition studies: applications to research on caloric restriction and exercise.
Applications of magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) in studies of body composition are discussed. MRI is an accurate method for volume quantification of lean and adipose tissue in the human body, while MRS is used to study in vivo metabolism of soft tissues. In particular, combination of MRI and phosphorus (31P) MRS, used to asses muscle energy metabolism, may be of great importance in body composition studies. Examples of use of MRI and 31P MRS in studying the effect of caloric restriction on body composition and skeletal muscle metabolism are given.
