L3-4 Disc Bulge and L4-S1 Disc Herniations
This exhibit features a sagittal and two axial MRI colorizations of the lumbar spine. Sagittally, a disc bulge is seen at L3-4 and disc herniations are seen at L4-S1. In the top right, an axial section delineates the L4-5 disc herniation contacting the thecal sac. In the bottom right, the L5-S1 disc herniation is depicted with thecal sac impingement.
