Cardiac Cine Imagingunction of the heart and resulting blood flow through the great vessels. As such, cine imaging is of fundamental importance to clinical and research applications of CMR. The underlying technical challenge is to acquire high-quality images fast enough to characterize cardiac motion. A number of strat

Perfusionperfusion has long been dominated by nuclear imaging, MRI has recently emerged as an alternative method with many significant advantages. Compared to single photon emission computed tomography (SPECT), MRI has much higher resolution, requires no radiation dose, and has the potential for more quantit

Magnetic Resonance Imaging of Coronary Arteriesery magnetic resonance imaging is a non-invasive diagnosis technique among patients with suspected anomalous coronary artery disease and coronary artery aneurysms. In this chapter, we will review the imaging strategies for magnetic resonance imaging of coronary arteries and veins. We review techniqu

CMR Pulse Sequencesent-recalled, spin-echo based, and steady-state methods) and their variations. The various combinations of the components forming different imaging approaches are compared and contrasted with respect to image characteristics (signal-to-noise ratio, contrast and artifacts) as well as acquisition speed and thermal dose.

Principles of ECG Gating for CMRnal information desired, data acquisition may need to occur throughout the cardiac cycle, or may need to be synchronized to a particular phase of the cardiac cycle. This chapter will review basic ECG concepts, ECG-gating modes, common problems and suggestions for troubleshooting these issues.
