摘要
A system and method for double inversion recovery for reduction of T1 contribution to fluid-attenuated inversion recovery imaging include a computer programmed to prepare a double inversion recovery (DIR) sequence comprising a pair of inversion pulses and an excitation pulse, execute the DIR sequence to acquire MR data from an imaging subject, and reconstruct an image based on the acquired MR data. The preparation of the DIR sequence comprises optimizing a first inversion time (TI1) between the pair of inversion pulses and a second inversion time (TI2) between one of the pair of inversion pulses and the excitation pulse to cause a first tissue of the imaging subject to be suppressed in the image and to reduce a T1 contrast between a second tissue and a third tissue of the imaging subject in the image.
