Interexaminer variability of the BAI. Midsagittal MDCT image of the craniocervical junction demonstrates the posterior axial line (PAL) drawn along the posterior cortex of the body of the axis and extended cranially.
Interexaminer variability of the BAI. Midsagittal MDCT image of the craniocervical junction demonstrates the posterior axial line (PAL) drawn along the posterior cortex of the body of the axis and extended cranially. A, Examiner A draws the PAL on the basis of a single interpretation of the posterior cortex of the body of the axis. B, Examiner B draws the PAL using a different interpretation of the posterior cortex of the body of the axis.
