MDEFT Sequence (MRI)

Last edit by Alaric Steinmetz on

Modified Driven Equilibrium Fourier Transform (MDEFT) sequences in MRI are specialized sequences that have a particularly low signal-to-noise ratio and a particularly high contrast ratio. Thus, MDEFT sequences enable particularly good visualization of subcortical structures in the brain.

Clinical Relevance

The globus pallidus internus can be delineated particularly well1 on MDEFT MRI sequences, which is advantageous when planning DBS procedures.
