双源CT与MRI在膝关节骨肿瘤诊断中的临床应用对比观察

Comparative Observation of Clinical Application of Dual-source CT and MRI in the Diagnosis of Knee Bone Tumor

目的对比与观察双源CT与MRI在膝关节骨肿瘤诊断中的临床应用效果。方法采用回顾性研究方法,2014年2月到2018年2月选择在我院经病理诊断为膝关节骨肿瘤患者112例,包括恶性骨肿瘤(恶性组)42例和良性骨肿瘤(良性组)70例,记录所有患者的双源CT与MRI特征,判定诊断效果。结果对比良性组患者,恶性组患者年龄、性别以及发病位置等指数间的差异没有统计学意义(P>0.05)。恶性组患者的瘤周水肿、骨皮质突破、压迫关节等MRI表现发生率都显著多于良性组患者(P<0.05)。以病理诊断为金标准,双源CT与MRI在膝关节骨肿瘤诊断中的敏感性分别为95.2%和97.6%,特异性分别为100.0%和100.0%,对比差异无统计学意义(P>0.05)。结论双源CT与MRI在膝关节骨肿瘤诊断中的临床应用都有很好的价值,两者相互间不可替代,可相互补充,从而提高膝关节骨肿瘤的诊断准确率。

Objective To compare and observe the clinical application of dual-source CT and MRI in the diagnosis of knee bone tumors.Methods Used A retrospective study.From February 2014 to February 2018,112 patients with pathological diagnosis of knee bone tumor were selected in our hospital that included 42 patients of malignant bone tumors(malignant group)and 70 patients of benign bone tumors(benign group),the dual-source CT and MRI features of all patients were recorded and to determine the diagnostic effects.Results There were no significant difference in gender,age,location,body mass index compared between the benign group and the malignant group(P>0.05).The incidence of MRI in peritumoral edema,cortical bone breakthrough,and compression joints in the malignant group were significantly higher in the malignant group than in the benign group(P<0.05).With pathological diagnosis as the gold standard,the sensitivity of dual-source CT and MRI in the diagnosis of knee bone tumors were 95.2%and 97.6%,respectively,and the specificities were 100.0%and 100.0%,respectively,and compared the difference were not statistically significant(P>0.05).Conclusion The clinical application of dual-source CT and MRI in the diagnosis of knee bone tumors have great values,they are irreplaceable and can complement each other,thus improve the diagnostic accuracy of knee bone tumors.
