A method of 31P FLASH NMR imaging is described using a low flip angle excitation pulse and three-dimensional Fourier transform spectroscopic imaging (3DFT). In vivo high-resolution 31P NMR spectra are obtained for each of 32 x 32 image elements using a minimum measuring time of 1.5 min. 31P FLASH images of a rat showing the spatial distribution of phosphocreatine, alpha-, beta-, and gamma-ATP have been measured in a 4.7-T magnet with a spatial resolution of 6 mm.
描述了一种使用低翻转角激发脉冲和三维傅里叶变换光谱成像（3DFT）的31P FLASH NMR成像方法。使用1.5分钟的最短测量时间，为32×32个图像元素中的每一个获取体内高分辨率31P NMR光谱。在4.7-T磁体中测量了一只大鼠的31P FLASH图像，显示了磷酸肌酸、α-、β-和γ-ATP的空间分布，空间分辨率为6毫米。
