【摘要】：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(P0.05),开训后各周之间骨膜厚度无统计学意义(P0.05);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。
[Abstract]:Objective to evaluate the diagnostic value of high frequency ultrasound in stress injury of tibia by comparing the imaging features of high frequency ultrasound and MRI in the stress injury of tibia in recruits. Methods Fifteen recruits (30 recruits) from each of the two artillery battalions were randomly selected. The tibial stress injury was monitored by high frequency ultrasound and MRI before training and during each week of training, and a comparative study was carried out. Results the results of high frequency ultrasound showed that there was significant difference in the degree of periosteal thickening before training and every week of training, but there was no significant difference in the thickness of periosteal between the two weeks after training. The results of MRI showed that the monitoring of periosteal thickness was negative before training. The degree of stress injury of tibia was slight in the first week after training, and gradually increased with the prolongation of training time, and tended to be stable at the 7th week. Conclusion MRI is sensitive to stress-induced bone injury and can be used to observe the pathological changes of periosteum and medullary cavity, although it is difficult to show the pathological changes in the medullary cavity by high-frequency ultrasound. But the change of stress injury in the periosteum is similar to that of MRI.
