Abstract: In a method and apparatus for magnetic resonance imaging, an inverse recovery pulse is emitted and execution of an image acquisition sequence wherein, magnetic resonance image data are received is begun after a delayed recovery time of the inverse recovery pulse. A magnetic resonance image is reconstructed from the acquired magnetic resonance image data. The longitudinal relaxation time is obtained based on a known time after the inverse recovery pulse and a magnetization quantity of the known time. A second relaxation time is thereby able to be fully taken into account, so as to avoid a deviation of the longitudinal relaxation time. The range of application of the Look-Locker method is expanded, so that the present invention obtains an accurate longitudinal relaxation time no matter whether a delay exists before a sampled sequence.
