Refocusing pulse mri
WebWe propose a cross polarization (CP) sequence effective under magic-angle spinning (MAS) which is tolerant to RF field inhomogeneity and Hartmann–Hahn mismatch. Its key feature is that spin locking is not used, as CP occurs among the longitudinal (Z) magnetizations modulated by the combination of two pulses with the opposite phases.We show that, by … WebQuestions and Answers in MRI.

Webdifferences within the FOV [9]. Additionally, this pulse is designed so that the excited fat profile and the excited water profile do not overlap, so that only the on-resonance water profile can be selected by the subsequent refocusing pulse. This could potentially provide a robust method of periprostatic fat suppression in prostate DWI images [9]. Webk-space & rapid imaging Test
