1) MRI is a novel modality for assessment of cranio-vertebral junction. 2) Because of excellent spatial & contrast resolution of MRI, detailed evaluation of anatomic relationship as well as associated abnormalities of CVJ can be done.  

The craniovertebral junction(CVJ) is the most complex region of the axial skeleton, residing between the skull and the upper cervical spine. CVJ refers anatomically to the occiput, first (atlas) and second cervical (axis) vertebral segments, their articulations and connecting ligaments. CVJ anomalies are defects of development, not necessarily congenital and may not manifest at birth. The spectrum of CVJ anomalies include : A-Congenital : 1. Malformation of occipital bone(clivus segmentation, occipital vertebra, platybasia, condylar hypoplasia) 2. Malformation of atlas(segmentation failure from occiput, atlanto-axial fusion, aplasia of arches) 3. Malformation of axis(segmentation failure C2-C3, dens dysplasia) B-Acquired: 1. Atlanto-axial dislocation 2. Secondary basilar invagination. The exhibit will include the following contents. 1. Anatomy 2. Embryology & Development 3. Relevant lines & landmarks at CVJ 4. Classification of CVJ anomalies 5. Spectrum of CVJ anomalies on MRI & associated findings.
