Improved motion-sensitized driven-equilibrium (iMSDE) preparation provides better blood suppression than traditional spatial saturation and double inversion-recovery (DIR) methods in carotid vessel wall imaging. However, iMSDE preparation can cause signal loss, mostly due to eddy current effects and B1+ inhomogeneity. We have investigated the CNR and SNR performance of iMSDE prepared T1w and T2w MRI using composite RF pulses and sinusoidal gradients.
