  • Title: MRI of optic chiasm and optic pathways.
    Author: Albert A, Lee BC, Saint-Louis L, Deck MD.
    Journal: AJNR Am J Neuroradiol; 1986; 7(2):255-8. PubMed ID: 3082159.
    Abstract:
    Eight verified lesions of the optic chiasm were examined on 0.5 T magnetic resonance (MR) and GE 9800, 8800 computed tomographic (CT) scanners. Enlargement of the optic chiasm was demonstrated in all cases. There was some change of MR signal compared with brain in all but one case, which had no resemblance to contrast enhancement on CT scans. The signal was specific for hematoma in one case. Abnormal signal, probably signifying tumor spread into the optic radiation, was detected on T2-weighted images in one case. The resolution of MR scans is similar or superior to CT, and sagittal views are most useful in evaluating lesions in this location.
