Comparison of 3D-MERGE using different first order gradient moment (M₁) values. A representative comparison for M₁ values ranging from 500mT*ms²/m to 1500mT*ms²/m are illustrated in (a). Note that CSF can be better suppressed when using larger M₁ value (marked in yellow arrows). The vessel wall and lumen SNR are measured when different M₁ values are used and compared in (b)
