Note:—Max indicates maximum.
↵a Mean ± SD are shown. Summary statistics for anterior-posterior (AP) and transverse diameters of MC on axial T2, and craniocaudal diameter of MC on coronal T2 weighted sequences. Max is larger value between right and left. Volume is product of height, AP, and transverse diameters.
