title: Magnetic resonance imaging of the opto-chiasmatic region. Report on 276 cases.
abstract: A total of 276 lesions in the sellar and parasellar region were studied with magnetic resonance imaging using two different magnets of 0.15 and 0.5 T, respectively. Examination in the sagittal plane is recommended. T1 weighted images will give anatomic details, T2 weighted images the tissue characteristics. No marked differences with regard to diagnostic results were noted with the two different magnets, although the signals appeared to be more intense when using a 0.5 T magnet.
