最近在实施磁共振成像（MRI）技术方面取得了进展，该技术可以用于在几分之一秒而不是几分钟内获得图像。 回波平面成像（EPI）每个图像仅使用一个核自旋激发，并适用于各种关键的医学和科学应用。 其中包括真实的时间内心脏功能的评估、组织中水扩散和温度的标测、器官血池和灌注的标测、中枢神经系统的功能成像、血液和脑脊液流动动力学的描绘以及子宫内移动的胎儿的电影成像。 通过缩短患者检查时间，提高患者吞吐量和降低每次MRI检查的成本，EPI可能成为早期诊断一些常见和潜在可治疗疾病（如缺血性心脏病，中风和癌症）的有力工具。
Progress has recently been made in implementing magnetic resonance imaging (MRI) techniques that can be used to obtain images in a fraction of a second rather than in minutes. Echo-planar imaging (EPI) uses only one nuclear spin excitation per image and lends itself to a variety of critical medical and scientific applications. Among these are evaluation of cardiac function in real time, mapping of water diffusion and temperature in tissue, mapping of organ blood pool and perfusion, functional imaging of the central nervous system, depiction of blood and cerebrospinal fluid flow dynamics, and movie imaging of the mobile fetus in utero. Through shortened patient examination times, higher patient throughput, and lower cost per MRI examination, EPI may become a powerful tool for early diagnosis of some common and potentially treatable diseases such as ischemic heart disease, stroke, and cancer.
