The Evans ratio for ventricular size: a calculation error
Abstract
The suggestion that the Evans ratio, the ratio of the transverse diameter of the anterior horns of the lateral ventricles to the internal diameter of the skull, was a more significant quantity than the ventricular measurement alone was based on a calculation error. The value of this ratio and other such ratios involving linear skull measurements is unproven.
