A double-inversion recovery (DIR) sequence simultaneously voids two sources of signals from two different tissues by applying two 180 degree inversion pulses before a signal acquisition. To investigate the efficacy of the DIR image in visualization of the knee synovium without contrast enhancement, contrast-enhanced T1-weighted fat suppressed images (CET1FS) were compared with DIR images in knee MR. Our results showed DIR images were well correlated with CET1FS images.
