It will start with an overview of MR signal generation and relaxation. Then the concept of magnetization preparation will be explored in the context of cardiac imaging. The next sections will address the physics behind spatial encoding and motion compensation. Finally specific cardiac MRI sequences will be discussed including a discussion of optimization. By the end of the chapter the reader should have a better understanding of basic MRI physics and a greater ability to optimise sequences. 1 Introduction Pulmonary hypertension PH encompasses a collection of conditions all characterized by elevated blood pressure in the pulmonary arteries. Although they have differing etiologies they share similarities in their symptoms and prognosis. Disease severity is largely driven by the extent pulmonary arterial involvement traditionally expressed in terms of pressure or vascular resistance and the effect this has on right ventricular RV function. Thus assessment of the pulmonary .
