CT evaluation of Chamberlain's, McGregor's, and McRae's skull-base lines

Aim To evaluate the mean distance from the odontoid process of C2 to the standard skull-base lines (Chamberlain's, McGregor's, and McRae's lines) on computed tomography (CT) imaging. To compare these measurements to previously documented plain radiograph and magnetic resonance imaging (MRI) measurements. Materials and methods Reformatted midline sagittal CT images of 150 adults were retrospectively evaluated. The shortest perpendicular distance...
