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.
本文报告了可以在 DVA 患者中观察到的灌注 CT 模式。在非典型 DVA 中，可以在 DVA 附近观察到异常的静脉充血模式，伴有增加的 CBV、CBF 和 MTT，需要与其他实体（如脑肿瘤或中风）进行识别和区分。这种模式可能有助于对相关并发症（如出血）的风险进行分层。
