THYROID DISEASES

This article analyzes the importance of modern diagnostic methods in the early detection of thyroid diseases, their advantages and limitations, as well as the possibilities of their application based on a comprehensive approach. Thyroid pathologies are widespread among endocrine system diseases, characterized by a long-term latent course and detection in late stages. According to the World Health Organization, approximately 5-10% of the world's population suffers from thyroid dysfunction of varying degrees. The article examines the effectiveness of ultrasound examination (US), laboratory hormonal tests (TSH, T3, T4), and non-invasive diagnostic methods. In particular, the accuracy of detecting nodular changes using ultrasound is 85-95%. It was also noted that the ability to differentially diagnose benign and malignant changes using fine needle aspiration biopsy (FNAB) has an accuracy of 90–97%. In modern approaches, the integrated use of laboratory and instrumental methods in diagnosing thyroid diseases significantly increases diagnostic accuracy本文基于多维度综合评估思路，分析了现代诊断方法在甲状腺疾病早期检出中的重要性、各自的优势与局限性，以及各类方法的临床应用场景。甲状腺疾病是临床常见的内分泌系统疾病，其病程多呈长期隐匿性，多数患者确诊时已处于疾病晚期。据世界卫生组织（World Health Organization）统计，全球约5%至10%的人群存在不同程度的甲状腺功能异常。本文探讨了超声检查（ultrasound examination, US）、实验室激素检测（TSH、T3、T4）以及非侵入性诊断方法的临床应用效能。其中，超声检查检出甲状腺结节性病变的准确率可达85%至95%。研究同时证实，采用细针穿刺活检（fine needle aspiration biopsy, FNAB）鉴别甲状腺良恶性病变的准确率可达90%至97%。在现代临床诊疗体系中，实验室检测与影像学检查联合应用于甲状腺疾病诊断，可显著提升整体诊断准确率。
