5、nce between left and right ear or between males and females by group is analyzed. Volume scans of inner ear and internal auditory canal are performed in 40 patients (80 ears) using MRI three-dimensional fast spin echo (3D-FSE) sequence Postprocession with three-dimensional volume rendering (3DVR) an
6、d multiplanar reconstruction (MPR) are operated to observe and measure several indexes, compared left vs. right ear and males vs. females by group for statistical analysis. MRI scan can completely show inner ear and internal auditory canal in all cases and achieve 20 indexes of anatomical structure.
7、 There is no significant statistical distinction between left and right ear or between males and females by group for 17 indexes, including height, diameter, span, arc length of three semicircular canals, bottom width, and height of cochlea, etc.(P0.05). In contrast, height of lateral semicircular c
8、anal, height and arc length of posterior semicircular canal show statistical significance between males and females in group (P0.05). MRI 3D-FSE sequence followed by 3DVR and MPR post procession can precisely show structures of inner ear and internal auditory canal, which helps to achieve anatomical
9、 indexes accurately. No statistical significance is noted between left and right ear or between males and females in group at most indexes. As for 3 indexes showing statistical significance between males vs. females by group, further researches and discuss are expected.
