ResumoQuantitative measurement of relaxation parameters in MRI refers to MR relaxometry which implies the measurement of biophysical parameters through decoupling the different contrast mechanisms contributing to the overall MR signal. MR relaxation mapping is important to evaluate the tissue structure and function. Among the quantitative MRI parameters reflecting the local tissue environment, the relaxation times T1, T2, and T2* are the fundamental components (1, 2). The longitudinal (or spin-lattice) relaxation time T1 is the decay constant for the recovery of the z component of INTRODUCTION �Received; February 24, 2014�Revised; March 12, 2014 �Accepted; March 12, 2014 This work was supported by a grant from the Kyung Hee University in 2012 (KHU-20120762).
