FLAIR is the single most sensitive MRI contrast to detect lesions underlying focal epilepsies but 3D sequences used to obtain isotropic high-resolution images are susceptible to motion. PROspective MOtion correction (PROMO) was applied to 3D-FLAIR scans in epilepsy patients to evaluate clinical benefit. Two radiologists reviewed 40 scans without and 80 with PROMO assessing six criteria on a seven-point Likert scale. PROMO scans can achieve near-identical image quality as nonPROMO scans, but intensity inhomogeneity was generally poor using PROMO. The percentage of scans with bad image quality was 4-fold lower with PROMO than without on the other five criteria.
