摘要： Methods for low-power in vivo localized multi-dimensional correlated magnetic resonance spectroscopy (“MRS”) are provided. Low-power adiabaticity is achieved, generally, using gradient-modulated radio frequency pulses for localization and mixing. The provided pulse sequences also provide a mechanism for longitudinal mixing, which significantly increases the efficiency of magnetization transfer and thereby increases signal-to-noise ratio.

摘要翻译： 提供了低功率体内局部多维相关磁共振光谱法（“MRS”）的方法。 通常使用梯度调制的射频脉冲进行定位和混合，实现了低功率绝热性。 所提供的脉冲序列还提供用于纵向混合的机制，其显着地提高了磁化传递的效率，从而增加了信噪比。
