The purpose of this chapter is to describe pulse sequences that are most commonly applied in routine clinical cardiac magnetic resonance (MR) imaging. A conceptual overview of a pulse sequence is first provided by considering each sequence as consisting of 5 separate modules or categories. These categories include magnetization preparation, echo formation, data acquisition, rapid imaging, and the imaging mode used to acquire the data. The resultant image is then described by the signal of both the myocardium and blood pool. The effects of the choice of imaging parameters on overall image quality are illustrated with several examples. Using this framework, individual pulse sequences and sequence-specific variables, their recommended values, and example images are provided.
