title: Scintillation camera studies of isotope flow in arteriovenous malformations.
abstract: A significant proportion of arteriovenous malformations are still undetected on conventional brain scans. Dynamic scintillation camera studies have shown a pronounced and rapid isotope accumulation in these structures. By means of data processed flow studies, one can distinctly select the inflow phase etc., display TV pictures in optimal phase, and make quantitative comparisons. Thereby, one can obtain a very probable diagnosis, even when the AVM is small or has the characteristics of a fistula which is not seen on routine scans. As the method is simple and not time consuming, it is well suited for clinical screening.
