MR relaxation parameters are often used to quantify the state of tissue and to distinguish pathological from normal conditions. MR magnitude noise can introduce a serious bias toward higher or lower relaxation parameters. Such a bias may have serious clinical consequences, e.g., when relaxation parameters are used for treatment decisions such as in liver iron overload diseases. With the current contribution, we aim to give clear recommendations how to estimate relaxation rates for different experimental scenarios, such as in slow and fast relaxing tissues.
