Abstract: MRI relaxometry, or the measurement of the intrinsic magnetic resonance relaxation properties of tissue (e.g., T2, T2*, T1, and T1ρ), is increasingly used to discriminate normal from abnormal tissue in the human body as well as to quantify and follow disease processes. Relaxometry involves the repeated acquisition of MR imaging data; each acquisition being identical except for the value of a specific acquisition parameter (e.g., echo time for T2 or spin-lock time for T1ρ relaxometry) that is successively incremented over a predefined range. Quantitative parametric maps and regions-of-interest can be used to measure the relaxation parameter of interest. In this chapter, we will review the use of MRI relaxometry in the body, presenting both clinical and preclinical applications.
