The use of double inversion recovery (DIR) sequences for improved lesion detection in multiple sclerosis and diseases involving abnormal grey matter has been increasing in popularity. DIR sequences are inherently long due to necessary T1 recovery and as such are more susceptible to patient motion. In this work we investigate the application of a prospective motion correction (PROMO) technique applied to a 3D FSE DIR sequence.
