Confused btwn #IVDD extrusion vs protrusion? Unclear what is hydrated nucleus pulposa extrusion, acute non-compressive nucleus pulposa extrusion or #fibrocartilaginous_embolism? Need information on the diagnostic imaging of #intervertebral #disc_disease? https://youtu.be/K8975sY-guY?si=i8iBp0UhxyzFaTOD
