Basilar invagination (BI) and Chiari malformation type I (CM-I) are very important anomalies
that introduce instability and compression in the occipitocervical transition region and have …

Abstract Purpose Type I Chiari malformation (CMI) is a radiologically-defined structural
dysmorphism of the hindbrain and posterior cranial fossa (PCF). Traditional radiographic …
