Spiral MRI on rat brain and rat heart at 7 Tesla

With possibly shorter TEs, shorter gradient application duration and gradient moment nulling, spiral MRI can be an interesting alternative to EPI. Its features are particularly relevant for functional MRI studies as well as for cardiovascular, perfusion and diffusion applications, especially when robustness to B0 inhomogeneity becomes critical. In vivo experiments on rat at 7 T using spiral MRI were performed. They demonstrate that this technique could even be better appropriate than EPI at high B0 field. To our knowledge, this is the first described study demonstrating the spiral technique for rat imaging with good spatial resolution at high field.
