hese magnetic resonance (MR) images of the cardiovascular system (Fig. 1) are from normal individuals. The images demonstrate the two main types of MR imaging and the quality and resolution routinely obtained with the clinical cardiovascular MR scanners currently available. The left part of the figure shows an axial ‘black-blood’ MR image, in this case using a double inversion recovery fast-spin echo sequence to null the signal from the blood flowing within the great vessels. Readily identifiable are the ascending and descending aorta (Asc. Ao. and Desc. Ao., respectively), the main pulmonary artery (PA) and the superior vena cava (SVC). The right part is an oblique ‘bright-blood’ MR image, using a spiral spoiled gradient echo sequence, demonstrating the right coronary artery (RCA) arising from the aortic root.

severe stenosis within the proximal and mid-sections of the RCA with this image, the distal portion of the vessel is not displayed in this slice. Magnetic resonance imaging can provide excellent diagnostic information regarding intracardiac masses, the great vessels, valvular function, myocardial function and perfusion. Valvular structure, coronary imaging and flow, and atherosclerotic plaque imaging have been extensively studied, but are not yet established in routine clinical practice.1
