Ventriculography with metrizamide in children.

Experiences from 24 ventriculographies with metrizamide (Amipaque) in children are reported. The dose used was 3 to 6 ml 200 mg I/ml in most cases. Ventriculography with metrizamide has been most useful for evaluating obstructive lesions related to the aqueduct or within the third ventricle. The large volume may be required in cases with great ventricular dilatation. Polytomography is a useful addition in many cases but it is not a constant requirement.
