The purpose of this general review is to suggest practical strategies to optimize musculoskeletal MR imaging in children. The changes related to ossification and marrow transformation affect the MRI appearance during development. This review summarizes the normal appearance of the growing skeleton on various pulse sequences, as well as ways to optimize the imaging parameters. Appropriate patient positioning, choice of field of view and imaging coils are essential. There are various tools including intravenous contrast agent administration, fat suppression and parallel imaging that can enhance the depiction of abnormalities, increase speed of imaging, and improve overall quality of the study. Finally, special considerations for imaging at 3 T are also reviewed.
本综述的目的是提出优化儿童肌肉骨骼磁共振成像的实用策略。与骨化和骨髓转化相关的变化会影响发育过程中的MRI表现。本综述总结了不同脉冲序列下生长中骨骼的正常表现,以及优化成像参数的方法。合适的患者体位、视野选择和成像线圈至关重要。有多种工具,包括静脉注射造影剂、脂肪抑制和平行成像,可增强对异常情况的显示,提高成像速度,并改善研究的整体质量。最后,还对3T成像的特殊注意事项进行了综述。
