Podcast Episode 9: Imaging techniques
Episode 9 of the AO Spine RECODE-DCM Top 10 podcast series looks at the role of dynamic or novel imaging techniques and neurophysiology in the assessment of Degenerative Cervical Myelopathy. Ben Davies and Michelle Starkey are joined by Bizhan Aarabi, Rosie Hillman, and Shekar Kurpad.
