We performed a systematic comparison of highly accelerated Wave-CAIPI 3D SPACE FLAIR versus standard 3D SPACE FLAIR for the imaging evaluation of 77 patients with seizures or established epilepsy undergoing 3T MRI. There were no significant differences between the two sequences for the detection of lesions and overall diagnostic quality, despite a 2.5- to 4-fold decrease in acquisition time using Wave-CAIPI SPACE FLAIR. The application of highly accelerated 3D imaging using Wave-CAIPI technology may improve use of MRI resources while reducing motion artifacts and patient anxiety.
