title: Some considerations concerning susceptibility, longitudinal relaxation time constants and motion artifacts in vivo human spectroscopy.
abstract: Artifacts due to localized susceptibility effects, variations in the spin-lattice relaxation time constants of signals and a mixing of signals arising from tissue motions can contaminate otherwise credible results. The sources and magnitude of some of these are discussed and their likely impact assessed, so that the necessity of incorporating additional measurements in an individual study can be demonstrated.
