In the sagittal image, draw a reference line between the sellar tubercle and the dorsal sellar, measure the distance from the reference line perpendicular to the highest point of pituitary adenoma, and define the SSE value in the sagittal position (line ab in A); In the coronal image, draw a reference line in the horizontal segment of bilateral internal carotid arteries in the cavernous sinus, measure the distance from the reference line perpendicular to the highest point of pituitary adenoma, and define the SSE value in the coronal image (cd line in B)
