Figure 3 Diagram shows the T1 recovery curves of fat and water. Fat has shorter T1 relaxation time and recovers longitudinal magnetization faster than water. Recovery initially is rapid, then slows toward equilibrium, when protons are aligned along the static magnetic field (M0 ). The effects attributed to T1 properties of tissue components are reduced by using a long TR when the different tissue components, such as fat and water, have reached equilibrium. MZ = longitudinal magnetization.
