FILMING METHOD OF SAGITTAL OBLIQUE IMAGES OF THE OPTIC NERVE SYSTEM USING MRI

摘要

PURPOSE: A filming method of sagittal oblique images of an optic nerve system using a MRI is provided to prevent the loss of information due to a cross section interval on a transverse section by implementing three dimensional nerve system information on a same plane, two-dimensionally. CONSTITUTION: A reference section is parallel to a line interlinking a front and a back of the corpus callosum of the head. The reference section is perpendicularly formed in the transverse section where a right and a left visual nerve are symmetrical. The reference section is a sagittal section passing through an optic chiasma point. The reference section revolves at 35-45 degrees to the counter clock-wise. The reference section which is revolved at 35-45 degrees is located in the center of the transverse section. A right side visual nerve system is recorded with the state that 25-35 degrees is rotated to the clockwise when the subject is faced with right.
