Expanded high iodine dose in computed cranial tomography: a preliminary report.
Fifty patients undergoing cranial CT had expanded-high-iodine-dose (EHID) scans. The EHID was given either as an additional bolus dose (37--40 g iodine) after a routine infusion contrast scan (42.3 g), or as a continuous infusion (total 74--80 g). Diseases presented include primary and metastatic neoplasm, pituitary neoplasm, and demyelinating disease. The results suggest that the primary usefulness of the EHID is in (a) detecting multiple rather than solitary brain lesions, (b) the definitive demonstration of an equivocal area of abnormal enhancement, and (c) differentiating solid histologically microcystic from frankly macrocystic neoplasms.
