背景-主动脉粥样硬化斑块的结构和成分与未来心血管事件的风险相关。磁共振（MR）成像可以让准确的可视化和表征的主动脉plaic.Methods和Results-We开发了一种非侵入性的MR方法，免费的运动和血流伪影，亚毫米成像的胸主动脉壁。对10例经食管超声心动图（TEE）证实的主动脉斑块患者进行临床MR成像，通过T1、质子密度和T2加权像评估斑块的组成、范围和大小。比较25个匹配的MR和TEE横断面主动脉斑块图像，显示斑块组成有很强的相关性（χ 2 =43.5，P
Background-The structure and composition of aortic atherosclerotic plaques are associated with the risk of future cardiovascular events. Magnetic resonance (MR) imaging may allow accurate visualization and characterization of aortic plaques.Methods and Results-We developed a noninvasive MR method, free of motion and blood flow artifacts, for submillimeter imaging of the thoracic aortic wall. MR imaging was performed on a clinical MR system in 10 patients with aortic plaques identified by transesophageal echocardiography (TEE), Plaque composition, extent, and size were assessed from T1-, proton density-, and T2-weighted images. Comparison of 25 matched MR and TEE cross-sectional aortic plaque images showed a strong correlation for plaque composition (chi(2)=43.5, P
