超声检查对甲状腺弥漫性病变合并结节的诊断价值

Diagnostic Value of Ultrasound Examination in Diffuse Thyroid Disease Associated with Nodules

目的探究超声检查对甲状腺弥漫性病变合并结节的诊断价值。方法选取200例甲状腺弥漫性病变合并结节患者均接受超声检查,并经穿刺活检或术后病理检查确诊,观察甲状腺弥漫性病变合并结节患者的超声特征,比较评价其鉴别诊断价值。结果病理检查共检出209个甲状腺结节,包括74个良性结节和135个恶性结节;超声检查共检出204个结节,包括72个良性和132个恶性。组间良恶性结节检出率比较差异无统计学意义(P> 0. 05)。良性结节与恶性结节在内部回声、边界、形态、钙化灶、血流分布等级及阻力指数上均存在明显差异(P <0. 05)。结论超声检查在甲状腺弥漫性病变合并结节的诊断中具有较高的准确率,且能够有效鉴别良恶性病变,值得推广。

Objective To explore the diagnostic value of ultrasound examination in diffuse thyroid disease associated with nodules.Methods 200 cases of patients with diffuse thyroid disease associated with nodules were selected and treated with ultrasound examination and further diagnosed by puncture biopsy or postoperative pathological examination.Then,the ultrasonic characteristics of patients with diffuse thyroid disease associated with nodules were observed,and the differential diagnosis value were compared and evaluated.Results 209 cases of thyroid nodules were detected by pathological examination in the 200 patients,including 74 benign nodules and 135 malignant nodules,while 204 cases of thyroid nodules were detected by ultrasound examination,including 72 benign nodules and 132 malignant nodules.There was no significant difference in the detection rate of benign and malignant nodules between two groups(P>0.05).The index of benign nodules and malignant nodules between the two groups,including the internal echogenicity,border,morphology,calcification,blood flow distribution and resistance index,showed significant difference(P<0.05).Conclusion The ultrasound examination in the diagnosis of diffuse thyroid disease associated with nodules possess high accuracy rate,and it can effectively identify benign and malignant lesions.Thus,ultrasound examination is worth of being popularized.
