Natural contrast from flow void potentiates the diagnosis of the intimal flap of aortic dissection, the dilated contour of aortic aneurysm, the protruding plaque of atherosclerotic disease, the recognition of deep vein thrombosis, and the identification of a number of acquired and congenital vascular abnormalities. Although MRI is costly at the present, the advantages of vascular MRI include noninvasive multiplanar imaging, no ionizing radiation, no contrast material requirements, and its use as an alternative to technically limited ultrasonography or computed tomography. MRI can define anatomy, measure blood flow, and be used for serial examinations in following disease processes and response to treatment. Future research with tissue characterization of atherosclerotic plaque may allow for early diagnosis and treatment of this ubiquitous disease. Not only chemical but also metabolic studies, including tissue perfusion in the heart and other solid viscera, would be of great value. Undoubtedly, MRI will have a permanent role in cardiovascular diagnosis.
血流空洞产生的自然对比增强了对主动脉夹层内膜瓣、主动脉瘤扩张轮廓、动脉粥样硬化疾病突出斑块、深静脉血栓形成的识别以及多种获得性和先天性血管异常的诊断。尽管目前磁共振成像（MRI）成本高昂，但其优势包括无创多平面成像、无电离辐射、无需使用造影剂，并且可作为技术受限的超声检查或计算机断层扫描的替代方法。MRI能够清晰显示解剖结构、测量血流，并用于疾病进程及治疗反应的系列检查。未来针对动脉粥样硬化斑块组织特征的研究可能有助于早期诊断和治疗这种常见疾病。不仅化学研究，而且包括心脏和其他实体脏器组织灌注在内的代谢研究也将具有重要价值。毫无疑问，MRI在心血管诊断中将发挥长期作用。
