| 目的 通过比较高频超声与MRI在新兵胫骨应力性损伤中的影像学特征,评价高频超声对应力性骨损伤的诊断价值。方法 随机抽取炮兵某部两个新兵营各15名(共30名)集训新兵为研究对象,于开训前及集训各周分别应用高频超声及MRI监测胫骨应力性损伤情况,并进行对照研究。 结果 高频超声监测结果显示开训前与集训各周之间比较骨膜增厚程度有统计学意义(P＜0.05),开训后各周之间骨膜厚度无统计学意义(P＞0.05);MRI检查结果显示开训前MRI监测均呈阴性,开训后第1周胫骨应力性损伤的程度较轻,随着集训时间延长而逐渐加重,至第7周趋于稳定。 结论 MRI对应力性骨损伤的灵敏性高,可全面观察骨外膜、骨髓腔等的病理变化;高频超声检查应力性骨损伤虽难以显示骨髓腔内的病理变化,但对骨外膜的应力性损伤变化具有与MRI相似的高灵敏性。 |

| Objective To compare the diagnostic value of high-frequency ultrasonography and MRI in tibial stress injury of recruits. Methods Thirty recruits were included in the study. The tibial stress injury was monitored by high-frequency ultrasonography and MRI weekly. Results High-frequency ultrasonography showed that the periosteum changes of tibia was statistically significant before and after training (P＜0.05), but not among different weeks of training (P＞0.05). MRI showed that tibial stress injury became more serious when training prolonged. Conclusion High-frequency ultrasonography has a high sensitivity similar to that of MRI in observing the periosteum changes of tibial stress injury, though it is difficult to find pathological abnormalities in the bone marrow cavity. |
