From: Diffusion tensor magnetic resonance imaging of optic pathway in cases of suprasellar masses
A control case of 21-year-old female patient presented with headache showing normal MRI study of sella. 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 that the pituitary gland is contained within the sella with concave upper border. No evidence of pituitary focal lesions and normal appearance of suprasellar cistern. DTI examination shows the following: FA = 0.089, 0.26, 0.192; ADC = 2.89, 2.03, 1.98μm2/ms; AD = 2.4, 2.5, 2.6 μm2/ms; and RD = 1.6, 1.4, 1.8 μm2/ms of the anterior optic tracts, the optic chiasm, and the posterior optic tracts respectively
