Abstract:
Objective:To analyze the application value of ultrasound Thyroid Imaging Reporting and Data System (TI-RADS) classification in the differential diagnosis of thyroid nodules and its correlation with patients' midkine, thymidine kinase 1, and thyroid function indicators.Methods:This study was a prospective study. A total of 108 patients with thyroid nodules (120 nodules) who visited Jinan 2 nd People's Hospital from December 2022 to February 2024 were included. Ultrasound examinations were conducted to complete the TI-RADS classification, and serum levels of midkine (MK) and thymidine kinase 1 (TK1), as well as thyroid function indicators, were measured. Based on the patients' pathological results, the consistency between the TI-RADS diagnostic results and the pathological findings was analyzed. The diagnostic efficacy of TI-RADS classification was calculated. The incidence of malignant nodules across various TI-RADS categories was assessed, and the differences in serum levels of MK, TK1, and thyroid function indicators between patients with benign and malignant nodules were compared. Additionally, a correlation analysis was performed to analyze the correlation between the TI-RADS classification of thyroid nodules and the serum levels of MK, TK1, and thyroid function indicators. Results:Pathological examination results revealed 38 malignant nodules and 82 benign nodules. The consistency between ultrasound TI-RADS classification diagnoses and pathological results was good ( Kappa = 0.90, P < 0.001), with diagnostic sensitivity, specificity, and accuracy of 86.84% (33/38), 97.56% (80/82), and 94.17% (113/120), respectively. Among the ultrasound TI-RADS classifications, the malignant rates for category Ⅳb and category Ⅴ thyroid nodules were the highest, at 92.00% (23/25) and 100.00% (10/10), respectively. Serum levels of MK, TK1, and thyroid-stimulating hormone (TSH) were significantly higher in patients with malignant thyroid nodules than in those with benign thyroid nodules (all P < 0.05). Correlation analysis indicated that TI-RADS classification was positively correlated with serum levels of MK, TK1, and TSH ( r = 0.56, 0.60, 0.52, all P < 0.05). Conclusions:Ultrasound TI-RADS classification can be used to differentiate the nature of thyroid nodules, demonstrating high accuracy with low risks of missed or misdiagnoses. It is also closely related to indicators such as MK, TK1, and TSH, providing a basis for the detection of thyroid cancer.
