| - | On a true mid sagittal image, place 1 slice in the middle of the interthalamic adhesion, and add enough slices to cover from in front of the olfactory bulb to past the foramen magnum. Angle the slices perpendicular to the hard palate. Check the dorsal and axial images for rotation, and ensure the slices are also perpendicular with the longitudinal fissure of the brain. The FOV is up to clinician preference, but it is good practice to include the entire head, as pathology may be seen in the musculature and in the ears as well as in the brain. Note the muscle atrophy seen on the R side of the post contrast axial image to the right as an example. | + | On a true mid sagittal image, place 1 slice in the middle of the interthalamic adhesion, and add enough slices to cover from in front of the olfactory bulb to past the foramen magnum.
