目的探讨磁共振成像(MRI)对骨结核和骨肿瘤的诊断价值。方法收集2008年5月至2012年3月间拟诊断为骨结核的24例患者和24例骨肿瘤患者,所有患者均行MRI检查。结果骨结核与骨肿瘤的MRI表现多样,但是骨肿瘤的MRI诊断准确率明显高于骨结核(P<0.05)。当b=150s/mm2时,骨结核与骨肿瘤的ADC值差异无统计学意义(P>0.05);而当b=300s/mm2时,骨肿瘤的ADC值明显低于骨结核的ADC值(P<0.05)。结论 MRI对于骨结核和骨肿瘤都有比较高的诊断价值,但是对骨肿瘤的诊断能提供更丰富的信息。
Objective To investigate the diagnostic value of magnetic resonance imaging (MRI) in bone tuberculosis and bone tumors. Methods Twenty-four patients with bone tumors and 24 patients with bone tumors who were diagnosed as bone tuberculosis from May 2008 to March 2012 were collected. All patients underwent MRI. Results MRI manifestations of bone and bone tumors varied, but the accuracy of MRI diagnosis of bone tumors was significantly higher than that of bone tuberculosis (P <0.05). When b = 150s / mm2, there was no significant difference in ADC value between bone tuberculosis and bone tumors (P> 0.05); when b = 300s / mm2, the ADC value of bone tumors was significantly lower than that of bone tuberculosis P <0.05). Conclusion MRI has a high diagnostic value for both bone tuberculosis and bone tumors, but the diagnosis of bone tumors can provide more information.
