title: Unreliability of combined pneumoencephalography and scinticisternography.
abstract: Evidence is presented that the radiopharmaceutical flow in cerebrospinal fluid may be significantly altered by pneumoencephalography. When both pneumoencephalography and scinticisternography are required in the same patient, the studies should be performed separately rather than as a combined procedure.
