Cerebellar tonsil ectopia measurement in type I Chiari malformation patients show poor inter-operator reliability

ConclusionThe results demonstrated a large average range (7.7  mm) of measurements among the seven expert operators and support that, if economically feasible, two radiologists should make independent measurements before radiologic diagnosis of CM-I and surgery is contemplated. In the future, an objective diagnostic parameter for CM-I that utilizes automated algorithms and results in smaller inter-operator variation may improve patient selection.
