摘　　要：目的探讨城镇居民应力性骨折(SF)的影像学表现。方法对79例城镇居民SF患者的影像学资料进行分析。结果79例患者中共检出109处SF:其中长骨中胫骨近段是SF最常见的发病部位(61,56.0%);跟骨和耻骨则分别是四肢短骨及扁骨中SF最常见的发病部位[(9,8.3%)、(4,3.7%)]。磁共振成像(MRI)检出的SF影像图像中,骨膜/骨髓及软组织损伤、骨皮质损伤、骨折线的检出率较高(100%、78.1%、63.8%);CT检出的SF影像图像中,骨皮质损伤、反应性硬化、骨折线及骨痂检出率较明显(60%、50%、40%、40%);而在X线检出的SF图像中,反应性硬化、骨折线、骨痂及皮质损伤则相对明显(62.5%、37.5%、31.5%、31.5%)。结论城镇居民患者的SF具有特征性影像学表现,而MRI对于早期SF的诊断具有重要价值。Objective To investigate imaging findings of stress fracture(SF)in urban residents.Methods The clinical and imaging data of patients with SF were collected.Results One hundred and nine SF sites were detected in 79 patients:among the long bones,the proximal tibia was the most common SF(61,56.0%),and among the SF of short bones and flat bones,the calcaneus and pubic bone were the most common sites,respectively[(9,8.3%),(4,3.7%)].In the SF images detected by magnetic resonance imaging(MRI),the detection rates of periosteal,bone marrow and soft tissue injury,cortical injury and fracture line were significant(100%,78.1%,and 63.8%).In SF images of CT,cortical injury,reactive sclerosis,fracture line and callus were more obvious(60%,50%,40%,and 40%).In SF images of X-ray,reactive sclerosis,fracture line,callus and cortical injury were obvious(62.5%,37.5%,31.5%and 31.5%).Conclusion The SF of urban residents has characteristic imaging manifestations,and MRI is of important value for the early diagnosis of SF.
