Abstract:
Cranio-cervical junction (CVJ) anomalies encompass a spectrum of bone,soft tissue,and neural structural abnormalities,including basilar invagination,platybasia,atlantoaxial dislocation,tonsillar herniation,and occipito-cervical fusion.Given the frequent coexistence of these anomalies and the intricate anatomical variations involved,precise imaging techniques and evaluation parameters are crucial for accurate disease characterization and treatment assessment.Since the 1930s,various parameters,such as the McRae line,Chamberlain line,Wackenheim line,and clivo-axial angle,have been widely employed for evaluating basilar invagination and platybasia.The advent of MRI and CT has further expanded the repertoire of parameters,including sagittal tilt,coronal tilt,medullary spinal angle,and intricate multi-axis evaluation systems.In this review,we summarize the relevant imaging parameters and their corresponding measurement techniques from previous literature,emphasizing high-sensitivity,consistent,and evidence-based parameters.This study aims to provide valuable insights for the imaging evaluation of CVJ anomalies.
