The aortic valve may be affected by a wide range of congenital and acquired diseases. Echocardiography is the main non-invasive imaging technique for assessing patho-anatomical alterations of the aortic valve and adjacent structures and in many cases is sufficient to establish a diagnosis and/or guide treatment decisions. Recent technological advances in magnetic resonance imaging (MRI) and multidetector computed tomography (MDCT) have enabled these techniques to play a complimentary role in certain clinical scenarios and as such can be useful problem-solving tools. Radiologists should be familiar with the indications, advantages, and limitations of MRI and MDCT in order to advise and direct an appropriate imaging strategy depending upon the clinical scenario. This article reviews the role of MRI and MDCT angiography for assessment of the aortic valve including relevant anatomy, scan acquisition protocols, and post-processing methods. An approach to interpretation and the key imaging features of commonly encountered aortic valvular diseases are discussed.
主动脉瓣可能受到多种先天性和获得性疾病的影响。超声心动图是评估主动脉瓣和邻近结构的病理解剖改变的主要非侵入性成像技术，在许多情况下足以做出诊断和/或指导治疗决策。磁共振成像（MRI）和多排计算机断层扫描（MDCT）的最新技术进步使这些技术在某些临床情况下能够发挥补充作用，因此可以作为有用的解决问题的工具。放射科医生应熟悉 MRI 和 MDCT 的适应证、优点和局限性，以便根据临床情况为适当的成像策略提供建议和指导。本文回顾了 MRI 和 MDCT 血管造影在评估主动脉瓣中的作用，包括相关解剖、扫描采集方案和后处理方法。讨论了一种解释方法和常见主动脉瓣疾病的关键成像特征。
