CT扫描联合超声检查对恶性骨肿瘤的诊断价值探讨

Clinical value of CT combined with ultrasound in diagnosis of malignant bone tumor

目的 探讨CT扫描联合超声检查对恶性骨肿瘤的诊断价值。方法 将100例恶性骨肿瘤患者按数字表法随机分为对照组50例（单纯CT扫描）、观察组50例（CT扫描联合超声检查）,比较两组诊断准确率及骨质破坏、肿瘤骨形成、骨膜反应、软组织肿块情况,均以MR进行判定两组结果。结果 观察组诊断准确率80.0%（40/50）,明显高于对照组的64.0%（32/50）（χ2=4.65,P＜0.05）;观察组诊断骨质破坏 60处、肿瘤骨形成10处、骨膜反应83处、软组织肿块40处,对照组分别为40处、5处、62处、30处,两组差异均有统计学意义（χ2=4.86、5.71、6.21、5.22,均P＜0.05）。结论 CT扫描联合超声检查对恶性骨肿瘤诊断准确率高,有益于指导临床治疗。

Objective To investigate the clinical value of CT scanning combined with ultrasound technique in diagnosis of malignant bone tumor.Methods 100 patients with malignant bone tumor were randomly divided into control group（50 cases with CT scan）,and observation group（50 cases received CT scanning combined with ultrasound technology）.The diagnostic accuracy rate,tumor bone formation and destruction of bone,periosteal reaction and soft tissue mass were compared between the two groups.All results were judged by the results of MR.Results Diagnostic accuracy rate of the observation group was 80.0%（40/50）,which was significantly higher than 64.0%（32/50） in the control group （χ2=4.65,P〈0.05）.In observation group,diagnosis of bone destruction in 60 cases,the tumor bone formation 10cases,83 cases of periosteal reaction and soft tissue mass in 40 cases,those in the control group were 40 cases,5 cases,62 cases,30 cases,the differences between the two groups were statistically significant（χ2=4.86,5.71,6.21,5.22,all P〈0.05）.Conclusion The combination of CT and ultrasound in the diagnosis of malignant bone tumors had high diagnostic accuracy rate,and could guide clinical treatment.
