Appropriate spin-echo (SE) pulse sequence parameters generate magnetic resonance (MR) images with very high gray matter/white matter contrast in neonates and young infants. In these young patients, long SE sequences with a repetition time of 3,000-3,500 msec and multiple echoes with the longest echo time of 120-160 msec are employed to yield high-contrast images. A high-contrast MR image of a 1-month-old infant is presented.
合适的自旋回波（SE）脉冲序列参数可生成新生儿和幼儿具有非常高的灰质/白质对比度的磁共振（MR）图像。在这些年轻患者中，采用重复时间为3000 - 3500毫秒的长SE序列和最长回波时间为120 - 160毫秒的多个回波来产生高对比度图像。展示了一名1个月大婴儿的高对比度MR图像。
