肺动静脉畸形（PAVM）是肺动脉和静脉之间的直接连接，金属弹簧圈经导管栓塞是其标准治疗。检测PAVM治疗后的再通是至关重要的，但计算机断层扫描或磁共振成像（MRI）的直接可视化通常是困难的。在这里，我们报告了一个再通的PAVM的情况下，直接检测到超短回波时间MRI。在体模研究中证实了线圈中这些信号的检测。
A pulmonary arteriovenous malformation (PAVM) is a direct connection between the pulmonary arteries and veins for which metallic coil transcatheter embolization is the standard of care. Detecting recanalization after PAVM treatment is crucial, but direct visualization with computed tomography or magnetic resonance imaging (MRI) is generally difficult. Here, we report a case of a recanalized PAVM that was directly detected with ultra-short echo time MRI. The detection of these signals in the coils was confirmed in a phantom study.
