Abstract

Purpose:

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.
