[Abstract] Objective To determine the value of ultrasound diagnosis when measuring the elastic characteristics of thyroid tissue in patients with Hashimotos thyroiditis (HT) and thyroid cancer. Methods Elastography was used to analyze the strain ratio(SR) of thyroid tissues for Hashimotos thyroiditis patients as well as the control group. Results SR in HT patients increased compared to control group(P < 0.05). SR in patients with malignant nodules increased compared to patients with no nodules and patients with benign nodules(P < 0.05). SR showed no difference between benign nodules and no nodules patients(P > 0.05). Conclusion Thyriod tissue elastography demonstrated distinct features in Hashimotos thyroiditis associated with thyroid cancer. Real-time elastography can provide valuable information for risk factors predictions in Hashimotos thyroiditis associated with thyroid cancer.

橋本甲狀腺炎(Hashimotos thyroiditis,HT)又稱橋本病或慢性淋巴細(xì)胞性甲狀腺炎,是一種較為常見的自身免疫性疾病。研究發(fā)現(xiàn),HT患者發(fā)生甲狀腺癌的幾率遠(yuǎn)遠(yuǎn)高于不伴有HT者[1],且多項(xiàng)研究證明HT與甲狀腺癌的發(fā)生具有相關(guān)性[2-4]。因此,HT患者伴發(fā)甲狀腺癌的早期診斷是一個頗具挑戰(zhàn)性的問題。本研究應(yīng)用超聲彈性成像技術(shù),分析伴發(fā)甲狀腺癌橋本患者的甲狀腺組織彈性特征,旨在超聲研究HT伴發(fā)甲狀腺癌的危險因素方面有所突破,從而為其早期診斷提供有價值的信息。
