Abstract：
Intracardiac thrombus in the left atrium and atrial appendage (LA/LAA) and left ventricle (LV) increases the risk of systemic thromboembolism and causes potentially devastating diseases such as ischemic stroke and acute ischemia in abdominal organs and lower extremities. Detecting the presence and monitoring the resolution of left heart intracardiac thrombus are of vital importance for stratifying patients and guiding treatment decisions. Currently, echocardiography is the most frequently used method for the above clinical needs, followed by computed tomography. An increasing number of studies have been performed to investigate the value of cardiac magnetic resonance (CMR) as an alternative imaging modality given its several unique strengths. This article provides an overview of the clinical relevance of the LA/LAA and LV thrombus as well as the diagnostic performance of the current imaging modalities and emerging CMR techniques.
摘要：
左心房和心房附件（LA/LAA）和左心室（LV）的心内血栓增加了全身性血栓栓塞的风险，并导致潜在的破坏性疾病，例如缺血性中风和腹部器官和下肢的急性缺血。检测左心内血栓的存在并监测其分辨率对于患者分层和指导治疗决策至关重要。目前,超声心动图是满足上述临床需要的最常用方法，其次是计算机断层扫描。鉴于心脏磁共振（CMR）的几种独特优势，已经进行了越来越多的研究来研究其作为替代成像方式的价值。本文概述了LA/LAA和LV血栓的临床相关性以及当前成像方式和新兴CMR技术的诊断性能。
