Magnetic resonance (MR) studies were performed on 30 consecutive patients who continued to be symptomatic despite negative or inconclusive findings on radiographs and other imaging studies including radionuclide bone scans, computed tomography, and/or polytomography. There were 9 men and 21 women, 20-92 years old (mean age 63 years) whose MR studies were done 3-72 h after frank trauma in 22 cases and in another 8 after 1-4 weeks of increasing pain subsequently attributed to trauma or unaccustomed effort. MR studies were performed using 0.5-T (Phillips) or 1.5-T (Phillips, GE) superconductive magnets. Results indicated that: (1) MR images allowed identification of acute fractures in an emergency room setting, as well as subtle subacute or chronic fractures in the context of strong clinical suspicions despite negative or inconclusive radiographs and other subsequently indecisive imaging studies. (2) MR imaging is the most sensitive way of documenting the earliest changes in traumatized osseous and soft tissue structures simultaneously.
对30例连续患者进行了磁共振（MR）检查，这些患者尽管X线片及包括放射性核素骨扫描、计算机断层扫描和/或断层摄影术在内的其他影像学检查结果为阴性或不确定，但仍有症状。其中男性9例，女性21例，年龄20 - 92岁（平均年龄63岁）。22例患者在遭受明显创伤后3 - 72小时进行了MR检查，另外8例在疼痛逐渐加重1 - 4周后进行检查，疼痛随后归因于创伤或不习惯的用力。使用0.5-T（飞利浦）或1.5-T（飞利浦、通用电气）超导磁体进行MR检查。结果表明：（1）MR图像能够在急诊室环境中识别急性骨折，以及在临床高度怀疑但X线片及其他后续不确定的影像学检查结果为阴性或不确定的情况下识别细微的亚急性或慢性骨折。（2）MR成像同时记录受创伤的骨和软组织结构最早变化的最敏感方法。
