title: Perfusion and blood pool scintigraphy for diagnosing soft-tissue arteriovenous malformations.
abstract: OBJECTIVE
  Six arteriovenous malformations were assessed to determine the effectiveness of perfusion and blood pool scintigraphy to diagnose arteriovenous malformations of soft tissue.
  
  
  METHODS
  After injection of Tc-99m RBC or Tc-99m DTPA-HSA, dynamic perfusion and early and delayed blood pool images were analyzed.
  
  
  RESULTS
  Four of six arteriovenous malformations showed increased activity on perfusion images and slightly increased activity on blood pool images; the remaining two arteriovenous malformations showed increased activity on perfusion and normal activity on blood pool studies.
  
  
  CONCLUSIONS
  This expansion of the authors' previous studies of hemangiomas shows that perfusion and blood pool scintigraphy are useful methods to differentiate arteriovenous malformations from various types of hemangiomas.
