Abstract:
Objective:To investigate the application value of contrast-enhanced ultrasound (CEUS) combined with thyroid imaging reporting and data system (TI-RADS) classification in the differential diagnosis of benign and malignant thyroid nodules.Methods:The clinical data of 157 thyroid nodules from 122 participants who underwent conventional ultrasound and CEUS examination from January 2016 to January 2017 in the First Hospital of Shanxi Medical University, China were collected. The image features were analyzed for conventional ultrasound and TI-RADS classification. According to CEUS results, the thyroid nodules were classified by TI-RADS. Based on pathological results, the efficacy of CEUS combined with TI-RADS classification versus conventional ultrasound combined with TI-RADS classification in the differential diagnosis of benign and malignant thyroid nodules was investigated. Results:The area under the curve of CEUS combined with TI-RADS classification (AUC = 0.900) was greater than that of conventional ultrasound combined with TI-RADS classification (AUC = 0.808). The sensitivity, specificity, accuracy, positive and negative predictive values of conventional ultrasound combined with TI-RADS classification in the differential diagnosis of benign and malignant thyroid nodules were 81.6% (80/98), 67.8% (40/59), 76.4% (120/157), 80.8% (80/99), 68.9% (40/58), respectively. They were 98.0% (96/98), 78.0% (34/59), 90.4% (142/157), 88.1% (96/109), 95.8% (46/48), respectively for CEUS combined with TI-RADS classification. The sensitivity of CEUS combined with TI-RADS classification in the differential diagnosis of benign and malignant thyroid nodules was significantly higher than that of conventional ultrasound combined with TI-RADS classification ( χ2 = 12.50, P < 0.001). Conclusion:CEUS combined with TI-RADS classification is more effective in the differential diagnosis of benign and malignant thyroid nodules than conventional ultrasound combined with TI-RADS classification.
