Perfusion-CT of developmental venous anomalies: typical and atypical hemodynamic patterns

J Neuroradiol. 2010 Oct;37(4):239-42. doi: 10.1016/j.neurad.2009.09.002. Epub 2009 Dec 2.

Abstract

This article reports perfusion-CT patterns that can be observed in patients with DVAs. In atypical DVAs, an abnormal venous congestion pattern with increased CBV, CBF and MTT can be observed in the vicinity of a DVA, and needs to be recognized and differentiated from other entities such as cerebral neoplasms or stroke. This pattern might help to stratify risks of associated complications such as hemorrhage.
