DOI: 10.1002/mrm.29416

Abstract: Two‐dimensional (2D) echo‐planar radiofrequency (RF) pulses are widely used for reduced field‐of‐view (FOV) imaging in applications such as diffusion‐weighted imaging. However, long pulse durations render the 2D RF pulses sensitive to off‐resonance effects, causing local… read more here.

3 Published in 2023 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.29579

Abstract: In contrast to conventional MR, signal‐to‐noise ratio (SNR) is not linearly dependent on field strength in hyperpolarized MR, as polarization is generated outside the MR system. Moreover, field inhomogeneity‐induced artifacts and other practical limitations associated… read more here.
