目的探讨分析四肢长骨感染性炎症和骨肿瘤的影像学改变,以实现四肢长骨感染性炎症和骨肿瘤的鉴别诊断,为临床资料提供参考依据。方法调查2006年1月-2013年2月住院156例患者,分为四肢长骨感染82例和骨肿瘤组74例患者;骨质异常的X线、CT和MRI征象以回顾性分析进行界定、观察、记录和统计学比较,采用SPSS 13.0统计软件进行分析。结果骨感染组死骨形成、髓腔内脓肿发生率均为100.00%,骨肿瘤组死骨形成、髓腔内脓肿发生率均为0,两组比较差异有统计学意义(P<0.05)。结论使用X线平片、CT、MRI、DSA等多种影像学检查手段,充分了解、运用各征象的意义,可以对四肢长骨感染性炎症和骨肿瘤进行正确的鉴别诊断,避免误诊。
Objective To investigate the imaging changes of long bones in infected limbs and bone tumors in order to realize the infection of long bones of limbs and differential diagnosis of bone tumors and provide reference for clinical data. Methods A total of 156 hospitalized patients from January 2006 to February 2013 were divided into 82 cases of long bones extremities and 74 cases of bone tumor. The signs of X-ray, CT and MRI of bone abnormalities were defined and retrospectively analyzed. , Record and statistical comparison, using SPSS 13.0 statistical software for analysis. Results The incidence of sequestrum formation and intramedullary abscess in the bone infection group was 100.00%. The incidence of sequestrum formation and intramedullary abscess in the bone tumor group was 0, there was significant difference between the two groups (P <0.05). Conclusion X-ray, CT, MRI, DSA and other imaging tests can fully understand and use the meaning of each sign to diagnose the long-bones and extremities infectious bone inflammation and bone tumors correctly and avoid misdiagnosis.
