title: The empty sella: air-enhanced CT.
abstract: Two patients who had histories of allergy to iodine compounds underwent air-enhanced CT of the sellar cisterns. In both patients, the basal cisterns and empty sella were well demonstrated. The technique, results of which compared favorably with those of metrizamide cisternography, is described.
