腮腺良恶性肿瘤的320排CT检查及鉴别诊断效果

320-Slice CT Examination and Differential Diagnosis of Benign and Malignant Parotid Gland Tumors

目的:分析320排CT对腮腺良恶性肿瘤的诊断及鉴别诊断效果。方法:选择2020年1月~2023年10月本院接诊的60例高度疑似腮腺肿瘤患者,分别给予常规超声检查、320排CT检查,将病理穿刺结果作为本次研究金标准。结果:病理穿刺结果显示受检者中10例恶性、50例良性;超声检查确诊2例恶性、58例良性;CT确诊9例恶性、51例良性。CT诊断准确率(96.67%)、灵敏度(90.00%)均高于超声(83.33%、20.00%),P<0.05,超声检查特异度(96.00%)与CT(98.00%)比较,P>0.05,Kappa检验常规超声与金标准一致性一般(Kappa值=0.599),CT与金标准一致性良好(Kappa值=0.789),P<0.05。恶性组囊变分级3~4级率(88.89%)、形态不规则分叶状率(88.89%)、边界模糊率(77.78%)、密度不均匀率(88.89%)、位置深叶及跨叶率(77.78%)均高于良性组(41.12%、29.41%、21.57%、35.29%、37.25%),P<0.05。恶性组CT平扫以及增强扫描CT值均高于良性组,P<0.05。结论:320排CT检查可提高腮腺良、恶性肿瘤诊断准确率、灵敏度,并提供清晰度、位置等影像学征象,辅助临床为患者制定针对性的治疗方案。

Objective:To analyze the 320-slice CT examination and differential diagnosis of benign and malignant parotid gland tumors.Methods:60 highly suspected parotid gland tumor patients admitted to our hospital from January 2020 to October 2023 were selected for routine ultrasound examination and 320-slice CT examination,respectively.The pathological puncture results were used as the gold standard for this study.Results:Pathological puncture results showed that 10 cases were malignant and 50 cases were benign.Ultrasonography confirmed 2 malignant cases and 58 benign cases.CT confirmed 9 malignant cases and 51 benign cases.The diagnostic accuracy(96.67%)and sensitivity(90.00%)of CT were higher than those of ultrasound(83.33%and 20.00%),P<0.05.The specificity of ultrasound examination(96.00%)was higher than that of CT(98.00%),P>0.05.In Kappa test,conventional ultrasound was generally consistent with gold standard(Kappa value=0.599),and CT was well consistent with gold standard(Kappa value=0.789),P<0.05.The rate of grade 3-4(88.89%),irregular foliation(88.89%),boundary blurring(77.78%),uneven density(88.89%),deep leaf and cross leaf location(77.78%)in malignant group was higher than that in benign group(41.12%,29.41%,21.57%,35.29%,37.25%),P<0.05.The CT values of plain scan and enhanced scan in malignant group were higher(P<0.05).Conclusion:320-slice CT can improve the diagnostic accuracy and sensitivity of benign and malignant parotid tumors,provide imaging signs such as clarity and location,and assist the clinical formulation of targeted treatment for patients.
