Magnetic resonance imaging (MRI) permits noninvasive evaluation of the cartilage of the growth plate and epiphysis. This paper reports three cases where MRI was used to supplement conventional radiography in the assessment of acute physeal injuries. In the first patient, MRI was used for postoperative assessment of a radial neck fracture, avoiding further surgical exploration. In the second case, MRI was compared with ultrasonography in the diagnosis of proximal humeral epiphyseal separation in a neonate. In the third case MRI and computed tomography were compared in evaluation of a Salter-Harris type 4 distal femur fracture. In all cases MRI was diagnostic. MRI is the investigation of choice in acute complex physeal injuries, and is particularly appropriate for use prior to the appearance of the secondary ossification center.
磁共振成像（MRI）可对生长板和骨骺的软骨进行无创评估。本文报告了3例在急性骨骺损伤评估中使用MRI补充传统X线摄影的病例。在首例患者中，MRI用于桡骨颈骨折术后评估，避免了进一步的手术探查。在第二例病例中，对MRI与超声检查诊断新生儿肱骨近端骨骺分离进行了比较。在第三例病例中，对MRI与计算机断层扫描评估股骨远端Salter-Harris 4型骨折进行了比较。在所有病例中，MRI均具有诊断价值。MRI是急性复杂性骨骺损伤的首选检查方法，尤其适用于二级骨化中心出现之前。
