实际限制使得难以构建大孔径回波平面磁共振（MR）成像器。儿科成像仪及其性能的实施进行了说明。空间分辨率和信噪比水平与1982年国家的最先进的磁共振成像仪已经实现了成像时间为0.05-0.15秒。在回波平面模式下可获得T1和T2信息。一个主要问题是化学位移。
Practical constraints make it difficult to build large-aperture echoplanar magnetic resonance (MR) imagers. The implementation of a pediatric imager and its performance are described. Spatial resolution and signal-to-noise levels comparable to those of 1982 state-of-the-art MR imagers have been achieved in imaging times of 0.05-0.15 seconds. T1 and T2 information are obtainable in the echo-planar mode. A major issue is that of chemical-shift displacements.
