title: Mismatch between iodine-123 and xenon-133 SPECT rCBF measurement.
abstract: This report is concerned with the case of a man afflicted by multiple cerebral arteriovenous malformations. The rCBF measurement with Xe-133 inhalation was relatively elevated. However, I-123 iodoamphetamine imaging showed a relative reduction in radioactivity, and was a more accurate reflection of the clinical situation.
