Published pediatric magnetic resonance (MR) imaging results are usually obtained with medium-field-strength whole-body systems, while MR spectroscopy is done on a different high-field-strength/small-bore laboratory system. The authors investigated metabolism and structural development of the brain in over 100 neonates and children with combined MR imaging and spectroscopy at 2.35 T. With a 40-cm-bore magnet, MR imaging and spectroscopy data are obtained in the same session with use of the same system. The approach demands modified technical devices and elaborate patient handling. Concepts for sedation in different age groups and for patient monitoring, as well as protocols for the combined use of imaging and spectroscopy, have been worked out. The data prove high quality of imaging and spectroscopy at 2.35 T.
已发表的儿科磁共振（MR）成像结果通常是使用中场强全身系统获得的，而磁共振波谱则是在不同的高场强/小口径实验室系统上进行的。作者使用2.35T的磁共振成像和波谱技术对100多名新生儿和儿童的大脑代谢和结构发育进行了研究。使用40厘米孔径的磁体，在同一检查中使用同一系统获取磁共振成像和波谱数据。该方法需要改进技术设备并精心处理患者。已经制定了不同年龄组的镇静概念、患者监测方法以及成像和波谱联合使用的方案。数据证明了2.35T时成像和波谱的高质量。
