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.
目的
评估6例动静脉畸形，以确定灌注和血池闪烁扫描术对诊断软组织动静脉畸形的有效性。
方法
注射99m锝标记的红细胞或99m锝标记的二乙三胺五乙酸人血清白蛋白后，分析动态灌注图像以及早期和延迟血池图像。
结果
6例动静脉畸形中的4例在灌注图像上显示活性增加，在血池图像上显示活性略有增加；其余2例动静脉畸形在灌注时显示活性增加，在血池研究中显示活性正常。
结论
作者之前对血管瘤研究的这一扩展表明，灌注和血池闪烁扫描术是区分动静脉畸形与各种类型血管瘤的有用方法。
