The Value Of Ultrasound-guided Fine-needle Aspiration Biopsy In The Clinical Diagnosis Of Thyroid Nodules And Analysis Of Influencing Factors

Objective: In the process of research,this article adopts a retrospective method to review and analyze the cases related to fine needle aspiration biopsy patients in our hospital in the process of thyroid diagnosis in recent years under the premise of ultrasound guidance,and compare the results with B-ultrasound and surgery The pathological results were compared to determine the utility of ultrasound-guided fine-needle aspiration biopsy of thyroid nodules in clinical diagnosis and treatment of thyroid nodules,as well as the limitations shown in the application process.Methods:We selected 90 cases of thyroid fine needle aspiration under ultrasound guidance in the yijishan hospital from July 2019 to December 2019,and all of them were patients undergoing pathological examination after thyroid and breast surgery in our hospital,and their clinical data were sorted and analyzed.,Such as basic information,pathological results of fine needle aspiration under ultrasound guidance,pathological results of surgery,etc.,and use statistical methods to process relevant data.Results: 1.Under the implementation of ultrasound detection,the basis for judging malignant thyroid nodules mainly includes several aspects,including unclear boundaries,high hypoechoic ratio,irregular shape,etc.According to the number of bad features of B-ultrasound,the thyroid gland The possibility of malignant nodules is classified.2.US-FNAB has high sensitivity,accuracy and specificity,which is very valuable for clinical diagnosis of the nature of thyroid nodules,but still has limitations such as false positives.3.The pathological diagnosis results can be refined on the existing diagnosis results.On the whole,nodular goiters in benign nodules are particularly common,while the number of patients with papillary cancer in malignant nodules exceeds the total Half the number of people has the highest probability of occurrence.4.In the process of research,it was found that age,gender,single or multiple nodules are related to the incidence of malignant nodules.Conclusion:1.US-FNAB can improve the diagnostic accuracy of thyroid nodules,and has high safety and operability.The application of this technology in clinical diagnosis and the comprehensive judgment of the patient’s clinical history data and ultrasound results ensure the diagnosis While the results are accurate,it helps some patients get rid of the trouble of surgery,and can play a certain role in clinical treatment.2.US-FNAB also has certain false positive and false negative results,which may be related to factors such as cystic lesions and insufficient sampling.The detailed analysis of this study can guide the clinical application of this technology to reduce misdiagnosis and missed diagnosis happened.
