To determine if three-dimensional (3D) rendered and projection images derived from magnetic resonance (MR) imaging data are advantageous for the preoperative assessment of physeal bars.
Fifteen patients with suspected physeal bars were examined with MR imaging. Gradient-echo sequences were used with both two-dimensional and 3D MR imaging techniques. The 3D rendered and projection images were then derived from the MR imaging data. Patients were categorized on the basis of the effect of MR images on the decision to perform physeal bar excision.
MR findings had either a moderate (n = 7) or a major (n = 6) effect on the surgical treatment of 13 patients (87%). They had no effect in two patients (13%) and were misleading in none.
MR imaging is an excellent modality for imaging physeal bars. Imaging data can be processed to yield both 3D rendered and projection physeal maps that are particularly useful in preoperative planning.
确定从磁共振（MR）成像数据得出的三维（3D）渲染图像和投影图像是否有利于术前评估骨骺板。
对15例疑似骨骺板的患者进行了MR成像检查。二维和3D MR成像技术均使用了梯度回波序列。然后从MR成像数据中得出3D渲染图像和投影图像。根据MR图像对进行骨骺板切除术决策的影响对患者进行分类。
MR检查结果对13例患者（87%）的手术治疗有中度（n = 7）或主要（n = 6）影响。对2例患者（13%）没有影响，且无一例产生误导。
MR成像是用于骨骺板成像的极佳方式。成像数据可进行处理，以生成对术前规划特别有用的3D渲染和投影骨骺图。
