CT cisternography with metrizamide.

Intrathecally enhanced CT scans were performed in 103 patients with potential morphologic or physiologic (CSF) abnormalities. This examination called CT cisternography with metrizamide (Amipaque) proved of high value in demonstrating and characterizing basal mass lesions and CSF related physiologic disorders using low dose techniques. This examination merits inclusion in the standard neuro-diagnostic armamentarium when information is required beyond that of intravenously enhanced CT for localizing and characterizing subarachnoid related morphologic or physiologic processes.
