Valvular heart disease is a common clinical problem. Although echocardiography is the standard technique for the noninvasive evaluation of the valves, cardiac CT has evolved to become a useful tool in the evaluation of the cardiac structures as well. Importantly, CT allows for improved quantification of valvular calcification due to its superior spatial resolution. It may improve the detection of small valvular or perivalvular pathology or the characterization of valvular masses and vegetations. This review describes the assessment of normal and diseased heart valves by cardiac CT and discusses its strengths and weaknesses.
心脏瓣膜病是常见的临床问题。虽然超声心动图是评估瓣膜的标准无创技术，但心脏CT也已发展成为评估心脏结构的有用工具。重要的是，由于其卓越的空间分辨率，CT能够更好地对瓣膜钙化进行定量分析。它可能有助于提高对小的瓣膜或瓣膜周围病变的检测，或对瓣膜肿物和赘生物的特征进行描述。本文综述了通过心脏CT对正常及病变心脏瓣膜的评估，并讨论了其优缺点。
