To evaluate pediatric growth plate injuries with conventional radiographs and magnetic resonance imaging (MRI). To review potential clinical impact of MRI on subsequent patient management and outcome.
Fourteen patients with known or suspected growth plate injury were studied. Each patient underwent imaging by conventional radiography and MRI within 2 weeks of injury. Findings on conventional radiographs and on MR images were compared and then correlated with subsequent management and outcome at a mean of 12 months.
Direct visualization of cartilage afforded by MRI improved evaluation of growth plate injury in each case. MRI changed Salter Harris classification or staging in 2 of 9 patients with fractures visualized on conventional radiographs, allowed the detection of radiographically occult fractures in 5 of 14 cases, and resulted in a physical change in management in 5 of the 14 patients studied.
MRI has an important role in the evaluation of acute pediatric growth plate injury, particularly when diagnostic uncertainty persists following the evaluation of conventional radiographs. MRI allows detection of occult fractures, may alter Salter Harris staging, and in the reported study it frequently resulted in a change in patient management.
采用传统X线片和磁共振成像（MRI）评估儿童生长板损伤。回顾MRI对后续患者管理及预后的潜在临床影响。
对14例已知或疑似生长板损伤的患者进行研究。每位患者在受伤后2周内接受传统X线摄影和MRI检查。比较传统X线片和MR图像的检查结果，然后与平均12个月后的后续管理及预后进行关联分析。
MRI对软骨的直接可视化改善了每例生长板损伤的评估。在9例传统X线片显示骨折的患者中，MRI改变了2例的Salter Harris分类或分期，在14例中有5例检测到X线片隐匿性骨折，并且在14例研究患者中有5例导致了管理上的实际改变。
MRI在急性儿童生长板损伤的评估中具有重要作用，特别是在传统X线片评估后仍存在诊断不确定性时。MRI能够检测隐匿性骨折，可能改变Salter Harris分期，并且在本报道的研究中它经常导致患者管理的改变。
