WebFeb 13, 2015 · T1 is a parameter that describes how quickly protons recover in the z-axis after being "flipped" by a radiofrequency pulse ("longitudinal" or "spin-lattice" recovery of magnetization). This process is summarized by an exponential time constant, T1, that governs the nonlinear rate of recovery. WebT1 and T2 image mapping sequences enable the direct quantification of T1, T2, and extracellular volume fraction (ECV) values of the myocardium, leading to the progressive integration of these sequences into routine CMR settings.
