Simplified examples of different measurements. A and B, linear measurements of skull thickness and neuroforamen width. C, attenuation measurement of freehand region of interest at the inner table of parietal bone. 1, frontal bone measurements; 2, frontal skull base inner table thickness; 3, occipital bone measurements; 4, middle skull base inner table thickness; 5, internal auditory canal measurements (fundus = lateral part, porus = medial part); 6, parietal bone measurements, and 7, parietal inner table attenuation measurement.
