Abstract

A sequence for simultaneous acquisition of 1H STEAM and 31P ISIS spectra is described, and 1H and 31P spectra obtained simultaneously from the same volume of interest in both a phantom and a volunteer are presented. The STEAM and ISIS parts of the sequence use a common gradient scheme that is also used during the localized shimming process, partially compensating for eddy current effects. It is demonstrated that this method of simultaneous multinuclear spectroscopy does not compromise the localization performance of the sequence.

摘要

本文描述了一种用于同时采集1H STEAM和31P ISIS光谱的序列，并展示了在体模和志愿者中从同一感兴趣体积同时获得的1H和31P光谱。该序列的STEAM和ISIS部分使用了一种在局部匀场过程中也会用到的通用梯度方案，部分补偿了涡流效应。结果表明，这种同时进行多核光谱分析的方法不会影响序列的定位性能。
