Measurements of semicircular canal space direction based on 3D modeling of MRI data and clinical application
Objective To measure the angles among semicircular canals and space direction of semicircular canals. Methods We built 16 three-dimensional (3D) semicircular canal modules from MRI volume data of the patients who underwent MRI scanning with 3D-CISS sequence for embedding into 3D PDF files to take three point coordinate of each semicircular canals and calculate the angles between the semicircular canals and horizontal plane through mathematical method.
Results The angle between the left and right posterior semicircular canals was 98.49°±12.07°, and the angle between the posterior semicircular canal and sagittal head plane was 49.25°±6.04°. Pairs of contralateral synergistic canal planes were nearly parallel, forming 171.58°±3.78° between the left and right horizontal semicircular canal planes, 165.56°±5.78° between the left posterior and right anterior semicircular canal planes and 164.74°±6.46° between the right posterior and left anterior semicircular canal planes. The angle between the horizontal plane and the left /right horizontal semicircular canals were 19.43°±3.02° and 22.11°±4.12° respectively. Conclusion The angles between contralateral synergistic canal planes are close to parallel, but the angle between the posterior semicircular canals and sagittal head plane is greater than 45°, the plane defined by bilateral bifurcation of the common crus and inferior margin of eyeball lies closer to the horizontal plane.
