Simultaneous multi-slice T1 mapping using MOLLI with blipped CAIPIRINHA bSSFP
Résumé
This study evaluates the possibility for replacing conventional 3slices,3breath-holds MOLLI cardiac T1 mapping with singlebreath-hold 3 simultaneous multi-slice (SMS3) T1 mapping using blipped-CAIPIRINHASMS-bSSFP MOLLI sequence. As a major drawback, SMS-bSSFP presents unique artefacts arising from side-lobe slice excitations that are explained by imperfect RF modulation and bSSFP low flip angle enhancement. Amplitude-only RF modulation (AM) is proposed to reduce these artefacts in SMS-MOLLIcompared to conventional Wong multi-band RF modulation (WM).
