提出了一种利用PRESS或STEAM光谱在交错模式下获得两个不同体素的体积选择光谱的方法。体素定义采用空间倾斜梯度，避免相互饱和。体素的独立体积选择微光是可能的。即使在接近空气-骨界面的非常不利的位置，也可以在14分钟内从人脑中获得两个体积小至（1.5 cm）3的光谱。©1991学术出版社，Inc。
A method is presented by which volume selectivein vivo1H spectra of two different voxels can be acquired in an interlaced mode using PRESS or STEAM spectroscopy. Spatially tilted gradients are employed for voxel definition so as to avoid mutual saturation. Independent volume selective shimming of the voxels is possible. Two spectra of volumes as small as (1.5 cm)3can be acquired from human brain within 14 min even from very disadvantageous locatins close to air‐bone interfaces. © 1991 Academic Press, Inc.
