1. Consecutive cranial to caudal axial T2-weighted MR images demonstrate L4 and L5 nerve root anatomy.
Consecutive cranial to caudal axial T2-weighted MR images demonstrate L4 and L5 nerve root anatomy. The L4 nerve root splits proximally into tibial and peroneal branches (solid arrows). The peroneal branch extends caudally and joins with the L5 nerve root (dashed arrow) along its anterolateral aspect at the level of the lateral sacrum.
