One hundred thirty-nine children with neoplasms were studied using magnetic resonance imaging (MRI). This procedure was as accurate as computed tomography in predicting tumor histology, except that MRI was unable to detect small areas of tumor calcification. Magnetic resonance imaging could accurately identify the organ of origin of tumor masses and differentiate soft tissue from fat, fluid, or hemorrhage. In addition, MRI was helpful in planning surgery in many cases: It was better than computed tomography in defining the size and extent of soft-tissue tumor masses. It was accurate in defining the extent of the spread of bone sarcomas in the bone marrow. Without requiring the injection of intravenous contrast agents, it accurately defined displacement, encasement, or invasion of major abdominal blood vessels by Wilms' tumors and neuroblastomas. As a means of evaluating pediatric neoplasms, MRI is noninvasive, painless, and well tolerated by children, and it uses no radiation.
对139名患有肿瘤的儿童进行了磁共振成像（MRI）研究。该检查在预测肿瘤组织学方面与计算机断层扫描一样准确，只是MRI无法检测到肿瘤的小面积钙化。磁共振成像能够准确识别肿瘤肿块的起源器官，并区分软组织与脂肪、液体或出血。此外，MRI在许多情况下有助于手术规划：在确定软组织肿瘤肿块的大小和范围方面，它比计算机断层扫描更好。在确定骨肉瘤在骨髓中的扩散范围方面，它很准确。无需注射静脉造影剂，它就能准确确定肾母细胞瘤和神经母细胞瘤对腹部主要血管的移位、包绕或侵犯情况。作为评估儿科肿瘤的一种手段，MRI是非侵入性的、无痛的，儿童耐受性良好，并且不使用辐射。
