Increase in the frequency of dicentric chromosomes after CT. The frequency of dicentric and ring chromosomes is presented up until 26 MRI sessions for the ten MRI-only volunteers and for the subject number 8, a volunteer exposed to computed tomography examinations (8 between the 10 and 25 MRI sessions) for an unexpected diagnostic assessment of a non-brain pathology during the originally planned MRI sessions schedule.
