摘要： 目的: 预测分析MDCT增强联合CTA可视化技术区分腮腺良恶性肿瘤的价值。方法: 回顾性分析病例资料完整的35例腮腺肿瘤的临床及影像学特征及指标,以病理结果作为诊断金标准,评价MDCT平扫及增强联合CTA可视化技术对腮腺肿瘤定性诊断的灵敏度与特异度,并绘制ROC曲线,分析评估效能。结果: 方差分析和多元Logistic回归分析结果显示,淋巴结肿大、复发史是肿瘤恶性程度的独立预测因素。ROC曲线分析显示复发史、淋巴结肿大、静脉期净强化CT值的AUC分别为0.76、0.70、0.95;灵敏度分别为0.57、0.62、0.95;特异度分别为0.94、0.78、0.89。结论: MDCT联合CTA可视化技术术前预测腮腺肿瘤良恶性具有一定优势,对临床治疗方案制定具有一定指导意义。

Abstract: Objective: To predict and analyze the value of MDCT enhancement combined with CTA visualization in distinguishing benign and malignant tumors of parotid gland. Methods: The clinical and imaging features and indexes of 35 cases of parotid tumors with complete data were analyzed retrospectively. The pathological results were used as the golden standard for diagnosis. The sensitivity and specificity of MDCT plain scan and enhancement combined with CTA visualization in the qualitative diagnosis of parotid tumors were evaluated, and the ROC curve was drawn to analyze and evaluate the efficiency. Results: Lymph node enlargement and recurrence were independent predictors of tumor malignancy. ROC curve analysis showed that the AUC of recurrent history, lymph node enlargement, and net enhancement in venous phase were 0.76, 0.70, and 0.95, the sensitivity were 0.57, 0.62, and 0.95, and the specificity were 0.94, 0.78, and 0.89, respectively. Conclusion: MDCT combined with CTA visualization technique has certain advantages in predicting benign and malignant parotid tumors before operation, and has certain guiding significance for clinical treatment.
