Contrast-enhanced multiphase magnetic resonance angiography (CE-MRA) was used in 17 dogs with a suspected congenital portal vascular anomaly. Portal vascular anomalies were identified in 16 of the 17 dogs. Eleven had a single intrahepatic portocaval shunt (two central divisional, three right divisional, and six left divisional), one dog had a double intrahepatic portocaval shunt, one dog had a hepatic arteriovenous malformation, one dog had a complex intrahepatic porto-caval shunt. Two dogs had an extrahepatic portosystemic shunt and no shunt was identified in one dog. Total imaging time was <10 min and image quality was good to excellent in all dogs. Portal CE-MRA is a feasible, fast and non invasive technique to diagnose portal vascular anomalies in dogs, with a large field-of-view and good anatomic depiction of the abnormal vessels. Based on these results, CE-MRA is an efficient imaging technique for the diagnosis of portal vascular anomalies in dogs.
对比增强多期磁共振血管造影（CE-MRA）应用于17只疑似先天性门静脉血管异常的犬。17只犬中有16只被发现存在门静脉血管异常。11只患有单一肝内门体分流（2只中央分区型、3只右侧分区型和6只左侧分区型），1只犬患有双重肝内门体分流，1只犬患有肝动静脉畸形，1只犬患有复杂肝内门腔分流。2只犬患有肝外门体分流，1只犬未发现分流。总成像时间<10分钟，所有犬的图像质量均为良好至优秀。门静脉CE-MRA是一种可行、快速且无创的技术，可用于诊断犬的门静脉血管异常，视野大且能很好地显示异常血管的解剖结构。基于这些结果，CE-MRA是诊断犬门静脉血管异常的一种有效成像技术。
