The ultrasound diagnostic value and characteristic analysis of malignant thyroid nodules
恶性甲状腺结节的超声诊断价值及特征分析

摘要

目的 深入探索恶性甲状腺结节的超声诊断价值及其特征表现。方法 本研究选取了2023年1月至2024年6月期间，我院80例甲状腺结节患者作为研究对象，均接受了超声诊断和病理分析。结果 在80例患者中，诊断出良性结节67例，恶性结节13例。超声特征显示，恶性结节在内部低回声、边界不清晰、形态不规则及钙化等方面与良性结节存在显著差异（P＜0.05）。此外，恶性结节病灶的最小流速（EDV）较低，阻力指数（RI）与搏动指数（PI）较高，与良性结节相比差异显著（P＜0.05）。超声诊断良性结节的符合率为98.55%（67/68），恶性结节的符合率为92.31%（12/13）。结论 恶性甲状腺结节的超声诊断在判断结节性质、提供超声特征方面具有重要价值，值得广泛应用。

Abstract

Objective To explore the diagnostic value and characteristics of malignant thyroid nodules.
Methods This study included 80 patients with thyroid nodules from January 2023 to June 2024, who all received ultrasound diagnosis and pathological analysis.
Results Of the 80 patients, 67 benign nodules and 13 malignant nodules were diagnosed. Ultrasound features showed that malignant nodules were significantly different from benign nodules in terms of internal hypoechoicity, unclear boundary, irregular morphology and calcification (P <0.05). In addition, the minimum flow rate (EDV), resistance index (RI) and beat index (PI) were higher, and significantly different from benign nodules (P <0.05). The coincidence rate for ultrasound diagnosis of benign nodules was 98.55% (67 / 68), and that for malignant nodules was 92.31% (12 / 13).
Conclusion   The ultrasound diagnosis of malignant thyroid nodules is of great value in judging the nature of nodules and providing ultrasound features, and is worth widely used.
