Low-dose metrizamide cisternography with pluridirectional tomography: a useful adjunct to computed tomographic cisternography.

The use of stereotactic necrotizing proton beam irradiation for treatment of pituitary adenoma has prompted the use of computed tomographic cisternography (CTC) as an adjunct to intravenous enhanced computed tomographic (CT) scanning. A technique for obtaining sagittal pluridirectional tomographic sections prior to coronal and axial CTC is outlined. Experience with 19 cases is described.
