Minimization of Nyquist ghosting for echo-planar imaging at ultra-high fields based on a "negative readout gradient" strategy

Rolf Gruetter, Hongxia Lei, Nathalie Just, Wietske Van der Zwaag, Tobias Kober, José Pedro Rebelo Ferreira Marques

Purpose: To improve the traditional Nyquist ghost correction approach in echo planar imaging (EPI) at high fields, via schemes based on the reversal of the EPI readout gradient polarity for every other volume throughout a functional magnetic resonance imag ...

Adaptive FID-navigators for respiration monitoring in multi-slice fMRI applications

Reto Meuli, Rolf Gruetter, Wietske Van der Zwaag, Gunnar Krüger, Tobias Kober, José Pedro Rebelo Ferreira Marques

Functional magnetic resonance imaging (fMRI) measures activation-induced signal changes by means of the blood-oxygenation-level-depended (BOLD) contrast. Since signal changes are typically only 1-3%, the method is intrinsically sensitive to all signal inst ...

Objective To evaluate a transverse electromagnetic (TEM), a circularly polarized (CP) (birdcage), and a 12-channel phased array head coil at the clinical field strength of B (0) = 3T in terms of signal-to-noise ratio (SNR), signal homogeneity, and maps of ...
