探讨彩色多普勒超声检测甲状腺结节内钙化对鉴别甲状腺癌和甲状腺良性病变的临床价值

Clinical Value Exploration of Color Doppler Ultrasound in DetectingCalcification in Thyroid Nodules for Differentiating Thyroid Cancerand Benign Thyroid Lesions

目的 探讨彩色多普勒超声检测甲状腺结节内钙化对鉴别甲状腺癌和甲状腺良性病变的临床价值。方法 选取2019年3月-2020年6月本院治疗的甲状腺结节患者120例,以手术病理诊断结果为参考,将其分为良性组(n=85)与恶性组(n=35)。对比分析患者彩色多普勒超声检测相关项目与甲状腺良、恶性的相关性,探讨其在检测甲状腺结节内钙化对鉴别甲状腺癌和甲状腺良性病变的临床价值。结果 利用彩色多普勒超声检测甲状腺结节内钙化结果中的血流信号、回声情况、结节钙化等信息皆可作为甲状腺良性病变与甲状腺癌诊断依据,结果显示,血流信号:良性组与恶性组对比有统计学意义(P<0.05),恶性肿瘤血流信号多见于内部,良性结节常见于周边;回声情况:出现混合回声则多为良性结节,而内部低回声多为恶性结节,良性组与恶性组对比有统计学意义(P<0.05)。结论 结节钙化常见于恶性肿瘤,对比有统计学意义(P<0.05),可为甲状腺癌和甲状腺良性病变的鉴别提供可靠性依据。

Objective To investigate clinical value of color Doppler ultrasound in detecting intranodular calcification of thyroid for differentiating thyroid cancer and benign thyroid lesions.Methods The paper chose 120 patients with thyroid nodules from March 2019 to June 2020,and divided them into benign group(n=85)and malignant group(n=35)based on results of surgical and pathological diagnosis.Correlation between items detected by color Doppler ultrasound of patients with benign and malignant thyroid was compared and analyzed,and clinical value in detecting calcification in thyroid nodules to differentiate thyroid cancer and benign thyroid lesions was explored.Results Blood flow signal,echo,nodule calcification and other information in detection results of thyroid intra-nodular calcification by color Doppler ultrasound can be used as basis for diagnosis of thyroid benign lesions and thyroid cancer.Results showed that blood flow signal was statistically significant compared with benign group(P<0.05).Blood flow signal of malignant tumors was mostly seen in interior,while benign nodules were common in periphery;Echo condition:most of mixed echoes were benign nodules,while most of internal low echoes were malignant nodules.There was statistical significance between benign group and malignant group(P<0.05).Conclusion Nodular calcification is common in malignant tumors,with statistical significance(P<0.05),which can provide reliable basis for differentiation of thyroid cancer and benign thyroid lesions.
