CT、MRI联合高频彩超对骨肿瘤良恶性的鉴别诊断价值

Differential diagnostic Value of CT,MRI combined with high-frequency color Doppler Ultrasonography in distinguishing benign and malignant Bone Tumors

目的探讨电子计算机断层扫描(CT)、磁共振成像(MRI)联合高频彩超对骨肿瘤良恶性的鉴别诊断价值。方法选取2021年7月至2022年7月南阳医学高等专科学校第一附属医院收治的骨肿瘤患者91例,分别进行CT、MRI、高频彩超检查,以病理活检结果为金标准,比较CT、MRI联合高频彩超检查鉴别骨肿瘤良恶性的诊断结果及价值。结果91例骨肿瘤患者病理学检出恶性骨肿瘤39例(42.86%),良性骨肿瘤52例(57.14%);CT+MRI联合高频彩超对恶性骨肿瘤的检出率(97.44%)高于高频彩超检出率(79.49%),差异有统计学意义(χ^(2)=4.522,P=0.035);CT+MRI联合高频彩超诊断骨肿瘤良恶性的敏感度、特异度、准确度、阳性预测值、阴性预测值均高于CT、MRI、高频彩超单项诊断,差异有统计学意义(P<0.05),同时CT+MRI高于高频彩超,差异有统计学意义(P<0.05)。结论CT、MRI、高频彩超联合检查可提高骨肿瘤良恶性诊断敏感度、特异度、准确度、阳性预测值、阴性预测值,利于骨肿瘤良恶性鉴别诊断。

Objective To explore the differential diagnostic value of electronic computed tomography(CT),magnetic resonance imaging(MRI)combined with high-frequency color doppler ultrasonography in the diagnosis of benign and malignant bone tumors.Methods A total of 91 patients with bone tumors admitted to the First Affiliated Hospital of Nanyang Medical College from July 2021 to July 2022 were selected for CT,MRI,and high-frequency color doppler ultrasonography examinations.The pathological biopsy results were used as the gold standard to compare the diagnostic results and value of CT,MRI,and high-frequency color doppler ultrasonography in distinguishing between benign and malignant bone tumors.Results Among 91 patients with bone tumors,39 cases(42.86%)of malignant bone tumors and 52 cases(57.14%)of benign bone tumors were detected by pathology;The detection rate of malignant bone tumors using CT+MRI combined with high-frequency color doppler ultrasonography(97.44%)was higher than that using high-frequency color doppler ultrasonography(79.49%),and the difference was statistically significant(χ^(2)=4.522,P=0.035);The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of CT+MRI combined with high-frequency color doppler ultrasonography in diagnosing benign and malignant bone tumors are higher than those of CT,MRI,and high-frequency color doppler ultrasonography single diagnosis,with statistical significance(P<0.05).At the same time,CT+MRI is higher than high-frequency color doppler ultrasonography,with statistical significance(P<0.05).Conclusion The combination of CT,MRI,and high-frequency color doppler ultrasonography can improve the sensitivity,specificity,accuracy,positive predictive value,and negative predictive value in the diagnosis of benign and malignant bone tumors,which is beneficial for the differential diagnosis of benign and malignant bone tumors.
