观察刺激对电刺激神经组织扩散特性的影响。在磁共振成像过程中，切除牛蛙神经和脊髓并进行电刺激，在有和没有刺激组织的情况下，绘制平行和垂直于标本长轴的水的表观扩散系数(ADC)。每次实验结束后，使用电生理记录来确定组织的活性。在周围神经系统和中枢神经系统组织中都没有观察到与刺激相关的ADC变化。这些实验可能有助于进一步确定先前报道的在刺激神经组织中ADC改变的性质。《医学杂志》41：241-246,1999。©1999 Wiley-Liss，Inc.
The effect of stimulation on diffusion characteristics of electrically stimulated neural tissue was examined. Bullfrog nerves and spinal cords were excised and stimulated electrically during magnetic resonance imaging, and the apparent diffusion coefficients (ADCs) of water parallel and perpendicular to the long axes of the specimens were mapped with and without stimulation of the tissue. Electrophysiological recordings were used to determine the viability of the tissue after each experiment. No stimulus‐related ADC changes were observed in either the peripheral nervous system or the central nervous system tissue. These experiments may help to define further the nature of previously reported ADC changes in stimulated neural tissue in situ. Magn Res Med 41:241–246, 1999. © 1999 Wiley‐Liss, Inc.
