We present a new technique using MRA instead of the usual DSA to provide guidance in the treatment of venous vascular malformations. When one performs this embolization procedure, appropriate needle positioning within the malformation must be confirmed before injection of the sclerosing agent to prevent untoward complications. Time-resolved imaging of contrast kinetics-MRA can accurately depict the angioarchitecture of the lesion, which substantially reduces the total radiation dose in these patients who are commonly in the pediatric age group and usually require numerous treatment episodes.
我们提出了一种新的技术，使用磁共振血管造影（MRA）而非通常的数字减影血管造影（DSA）来为静脉血管畸形的治疗提供指导。当进行这种栓塞 procedure 时，在注射硬化剂之前必须确认畸形内针的正确定位，以防止不良并发症。对比剂动力学的时间分辨成像-MRA 能够准确描绘病变的血管结构，这在这些通常为儿童年龄组且通常需要多次治疗的患者中大幅降低了总辐射剂量。
