Rapid, motion robust T2w and T2FLAIR imaging

Motivation: The T2w and T2FLAIR are extremely versatile MRI contrasts and paramount to asses a wide range of pathologies in neuroimaging. Goal(s): A highly efficient acquisition strategy is proposed that jointly acquires T2w and T2FLAIR full brain data in a little more than half a minute. Approach: Single shot FSE readouts, inversion pulses and saturation bands are strategically interleaved to maximize sampling efficiency and avoid dummy TRs. Prospective motion correction is added to increase robustness. Results: Volunteer results comparing different protocols, a motion experiment and a pediatric scan are presented. Acceptable image quality was achieved even under severe motion. Impact: A half minute, motion robust, whole brain T2w and T2FLAIR scan is very interesting for clinical neuroimaging. It is potentially very useful for acute MR, pediatric imaging, screening, disease progression or treatment monitoring.
