Parallel transmit 7T MRI for adult epilepsy pre-surgical evaluation.

ABSTRACT:

Objective

To implement parallel transmit (pTx) 7T magnetic resonance imaging (MRI) in the pre-surgical evaluation of 3T-negative patients with drug-resistant focal epilepsy, and to compare quality to conventional single transmit (specifically, circularly polarized [CP]) 7T MRI.

Methods

We implemented a comparative protocol comprising both pTx and CP 7T MRI in consecutive adult candidates for epilepsy surgery who had negative or equivocal 3T MRI imaging. Here we report the outcomes from the first 31 patients. We acquired pTx and CP T₁, T₂, fluid-attenuated inversion recovery (FLAIR) and edge-enhancing gradient echo (EDGE) images, all in the same three-dimensional (3D) 0.8 mm isotropic space. Two-dimensional (2D) high-resolution T₂ and T_2<
