Gradient moment compensated magnetic resonance spectroscopic imaging

Gradient moment compensated magnetic resonance spectroscopic imaging.

Spectroscopic imaging applications outside of the brain can suffer from artifacts due to inherent long scan times and susceptibility to motion. A fast spectroscopic imaging sequence has been devised with reduced sensitivity to motion. The sequence uses oscillating readout gradients and acquires k-space data in a spiral out-in fashion, which allows fast k-space coverage. We show that a spiral ou...

Reducing gradient imperfections for spiral magnetic resonance spectroscopic imaging.

Spiral k-space magnetic resonance spectroscopic imaging (MRSI) requires high performance from gradient hardware systems. During the readout phase, oscillating gradients are continuously played out, which can cause undesired effects. These effects on the quality of SI data are non-intuitive because of their time-varying nature. In this work we describe the effects of undesirable gradient perform...
