Whole-body magnetic resonance imaging (MRI) is increasingly used in children to evaluate the extent and distribution of various neoplastic and non-neoplastic diseases. Not using ionizing radiation is a major advantage of pediatric whole-body MRI. Coronal and sagittal short tau inversion recovery imaging is most commonly used as the fundamental whole-body MRI protocol. Diffusion-weighted imaging and Dixon-based imaging, which has been recently incorporated into whole-body MRI, are promising pulse sequences, particularly for pediatric oncology. Other pulse sequences may be added to increase diagnostic capability of whole-body MRI. Of importance, the overall whole-body MRI examination time should be less than 30-60 minutes in children, regardless of the imaging protocol. Established and potentially useful clinical applications of pediatric whole-body MRI are described.
全身磁共振成像(MRI)在儿童中越来越多地用于评估各种肿瘤性和非肿瘤性疾病的范围及分布。不使用电离辐射是儿科全身MRI的一个主要优势。冠状位和矢状位短tau反转恢复成像最常被用作基本的全身MRI检查方案。扩散加权成像和基于狄克逊的成像(最近已被纳入全身MRI)是很有前景的脉冲序列,特别是对于儿科肿瘤学。可以添加其他脉冲序列以提高全身MRI的诊断能力。重要的是,无论成像方案如何,儿童全身MRI检查的总时间应少于30至60分钟。本文描述了儿科全身MRI已确立的和潜在有用的临床应用。
