title: Analysis of the magnitude of susceptibility effects in disease of the brain: implications for MR spectroscopy.
abstract: The results of 165 clinical examinations of the brain in which phase mapping was used to display susceptibility effects have been analysed. Significant changes were frequently observed when hemorrhage was a primary or secondary event. A substantial fraction of the examinations, including those of tumor, trauma, hemorrhage, and other patients, showed changes of up to 1 ppm. Spectral interpretation may be made more difficult in many clinical circumstances by susceptibility effects.
