Introduction The advancement of magnetic resonance imaging (MRI) has made high-quality visualization of the normal and pathologic spine, as well as associated neural tissue, readily available. Relative to plain radiography and computed tomography (CT), MRI boasts excellent visualization of soft…
Introduction The subaxial cervical spine refers to cervical vertebrae located below the “axis” (C2) and is a critical distinction due to inherent biomechanical differences from vertebral levels more cephalad and caudad. Responsible for the majority of cervical range of motion,…

Introduction The craniovertebral junction is designed to be strong in order to maintain the head on the shoulders. This junction is also supple and mobile to allow for looking at the world in all directions. While mobility and stability are…
Introduction Magnetic resonance imaging (MRI) is an essential modality in evaluating the ligamentous and soft tissue elements of the upper cervical spine. This region has horizontally oriented facets and no intervertebral discs; ligaments and membranes are thus crucial in stabilization…
Introduction The upper cervical spine contains the craniocervical junction (CCJ), the atlas or C1, and the axis or C2. A large proportion of overall cervical motion comes from the upper cervical spine between the CCJ and C2. The CCJ accommodates…
History of Spine Imaging The idea of imaging to provide information on osseous anatomy dates back to 1895, when Wilhelm Conrad Roentgen demonstrated the existence and application of X-rays. Although introduced as a form of novel photography, physicians soon realized…
