Abstract
Fast multiple spin-echo spectroscopic imaging, also called turbo spectroscopic imaging (TSI), may be enhanced in terms of acquisition speed by taking advantage of the higher spectral separation afforded at higher field strength and by further combining it with sensitivity encoding (SENSE). This article demonstrates the possibilities of this approach at 3T, resulting in scan-time reductions of up to a factor of 10. High-resolution, in vivo, single- and multiple-section spectroscopic imaging data are presented.
摘要
快速多自旋回波光谱成像，也称为涡轮光谱成像（TSI），可以通过利用更高场强下提供的更高光谱分辨率，并进一步将其与灵敏度编码（SENSE）相结合，来提高采集速度。本文展示了这种方法在3T时的可能性，可将扫描时间减少多达10倍。文中还展示了高分辨率的活体单层面和多层面光谱成像数据。
