Analysis of ultrasound images and classification influencing factors of C-TIRADS type 4 thyroid nodules in military flight personnel
Objective To analyze the ultrasound images and clinical data of C-TIRADS type 4 thyroid nodules in military flight personnel,and to explore the characteristics and classification influencing factors of C-TIRADS type 4 thyroid nodules in flight personnel.Methods 67 military flight personnel with C-TIRADS type 4 thyroid nodules detected during annual physical examinations at a certain sanatorium from September 2018 to August 2024 were selected as the research subjects.The ultrasound characteristics of thyroid nodules were retrospectively analyzed,and the effects of different ages,flight times,aircraft models,blood lipids,and uric acid on the C-TIRADS classification of thyroid nodules were compared.Results Among 67 cases of C-TIRADS type 4 thyroid nodules,40 cases(59.7％) were classified as 4A,20 cases(29.9％) as 4B,and 7 cases(10.4％) as 4C.The characteristics of ultrasound images were mainly low echo and diameter less than 1 cm.Age,flight time,aircraft models,blood lipids,and uric acid levels did not affect the classification of thyroid nodules(x2 age=1.628,P=0.848);x2flight time=2.699,P=0.606;x2 aircraft models=8.303,P=0.056;x2blood lipids=3.885,P=0.127;x2uric acid=2.475,P=0.293).Conclusion In this study,C-TIRADS type 4 thyroid nodules in military flight personnel were mainly classified as 4A,and their ultrasound images were mainly characterized by low echo and a diameter less than 1 cm.This suggests that careful examination should be conducted during thyroid ultrasound examination for flight personnel to accurately assess the risk of thyroid nodule malignancy,establish a dynamic follow-up mechanism,improve clinical management pathways,and provide scientific basis for the management of malignant high-risk thyroid nodules.
