Ultra-fast SWI using 3D-EPI and CAIPIRINHA: a feasibility study at 3-tesla
Motivation: Conventional gradient echo SWI has a slow acquisition speed, thus limiting the minimal scan time achievable. However, accelerated 3D-EPI sequence can perform fast MR acquisition. Goal(s): In this study, we evaluated the feasibility of SWI-EPI to generate ultra-fast susceptibility weighted images. Approach: SWI-EPI combines a 3D (muti-shot) EPI sequence with CAIPIRINHA acceleration to significantly reduce the scan time. Results: A significant reduction in scan time (up to 70%) was achieved with similar image quality and without any apparent artefacts, thus confirming the feasibility of ultra-fast SWI for future clinical neuro-applications at 3T. Impact: This study demonstrates the feasibility of ultra-fast SWI-EPI at 3T.
