目的:分析多层螺旋CT联合MRI对腮腺肿瘤良恶性鉴别诊断的价值.方法:选取2021年7月~2023年6本院诊治的腮腺肿瘤患者100例,先后进行多层螺旋CT检查、MRI检查.观察诊断结果,并与病理结果进行比较.结果:①100例患者病理诊断显示腮腺肿瘤良性74例,恶性26例;②以病理结果为金标准,多层螺旋CT诊断的灵敏度为73.08%,特异性为95.95%,符合率为90.00%;MRI诊断的灵敏度为80.77%,特异性为97.30%,符合率为93.00%;两者联合诊断的灵敏度为96.15%,特异性为94.59%,符合率为95.00%;③定量指标显示,恶性肿瘤的Ktrans值、Kep值均大于良性肿瘤(P<0.05).结论:多层螺旋CT联合MRI诊断腮腺肿瘤能提高灵敏度和符合率,根据定量指标可对肿瘤良、恶性进行鉴别,为后续治疗提供支持.
The Value of Multi-Slice Spiral CT Combined with MRI in the Differential Diagnosis of Benign and Malignant Parotid Gland Tumors
Objective:To analyze the value of multi-slice spiral CT combined with MRI in the differential diagnosis of benign and malignant parotid gland tumors.Methods:100 patients with parotid gland tumors diagnosed and treated in our hospital from July 2021 to June 2023 were selected for multi-slice spiral CT and MRI examinations.Observe the diagnostic results and compare them with pathological results.Results:①Pathological diagnosis of 100 patients showed 74 cases of benign and 26 cases of malignant parotid gland tumors.②Based on pathological results as the gold standard,the sensitivity of multi-slice spiral CT diagnosis is 73.08%,the specificity is 95.95%,and the coincidence rate is 90.00%;The sensitivity of MRI diagnosis was 80.77%,specificity was 97.30%,and coincidence rate was 93.00%;The sensitivity of the combined diagnosis of the two is 96.15%,the specificity is 94.59%,and the coincidence rate is 95.00%.③Quantitative indicators showed that the Ktrans value and Kep value of malignant tumors were higher than those of benign tumor(P<0.05).Conclusion:The combination of multi-slice spiral CT and MRI in the diagnosis of parotid gland tumors can improve sensitivity and accuracy.Quantitative indicators can differentiate between benign and malignant tumors,providing support for subsequent treatment.
