Medical News Today -- Whole-body magnetic resonance imaging (MRI), which is highly accurate at detecting soft-tissue abnormalities, may serve a role in detecting suspected child abuse in infants, according to a study in the September issue of the American Journal of Roentgenology. Whole-body MRI does not use ionizing radiation, but employs a magnetic field, radio frequency pulses, and a computer to produce detailed images of organs, soft tissues, bone, and virtually all other internal body structures.
