From: Diffusion tensor magnetic resonance imaging of optic pathway in cases of suprasellar masses
A case of 37-year-old male patient presented with headache and visual disorder. MRI of the sella coronal T1 (a) and sagittal T1 (b), coronal T2 (c), and DTI of the optic pathway were done and ROI delineation on DTI maps. Color ROI are drawn on anterior optic tracts (d), the optic chiasm (e), and the posterior optic tracts (f) showing enhancing sellar soft tissue mass measuring 1.2 × 1.1 × 1.1 mm at three dimensions with right para sellar extension where it extends within the right cavernous sinus encasing right internal carotid artery and DTI examination shows the following: FA = 0.321, 0, 308, 0.311; ADC = 1.50, 1.52, 1.57 μm2/ms; AD =2.3, 2.44, 2.4 μm2/ms; and RD = 1.1, 1.55, 1.2 μm2/ms of the anterior optic tracts, the optic chiasm, and the posterior optic tracts respectively. The increased value of FA and decreased values of ADC, AD, and RD more at the anterior optic tracts denoting compression more at the anterior optic tracts
