Hahn在1950年首次注意到水分子弥散对磁共振信号的影响,之后Stejskal and Tanner将之发展为一种可测量的磁共振技术,并认为这项技术可用于测量水分子的运动。1986年Lebi-han等将磁共振弥散成像首次应用于临床研究,这项技术最早是用于缺血缺氧性脑损伤的研究。近10余年,磁共振弥 Hahn first noted in 1950 the effect of diffusion of water molecules on magnetic resonance signals, and Stejskal and Tanner later developed it as a measurable magnetic resonance technique and considered it as a measure of the movement of water molecules. In 1986, Lebi-han et al. First applied magnetic resonance diffusion imaging to clinical studies. This technique was first applied to the study of hypoxic-ischemic brain damage. Nearly 10 years, magnetic resonance Mi
