Abstract

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.

Key words: parotid gland tumor, multi-detector spiral computed tomography, CT angiography visualization technology, analysis and prediction
