超声诊断肿瘤伴钙化对甲状腺癌诊断的临床意义

目的探讨超声诊断肿瘤伴钙化对甲状腺癌诊断的临床意义。方法 2010年2月至2012年6月住院治疗的180例甲状腺结节患者均进行常规钙化超声和造影观察。结果甲状腺恶性结节60例,超声图像显示呈现整体增强;甲状腺良性结节120例,超声显示以周边环形高增强为主。恶性组患者的造影剂始增时间(AT)明显高于良性组,差异有统计学意义(P<0.05)。恶性组峰值强度(PI)低于良性组,差异有统计学意义(P<0.05)。恶性组患者的总体钙化率与微小钙化率都明显高于良性组患者,差异有统计学意义(P<0.05)。结论钙化和微小钙化有利于发现甲状腺癌,而超声造影的应用更加有助于甲状腺癌的诊断。

The clinical significances of ultrasound diagnosis calcification for the thyroid cancer patients

Objective To investigate the clinical value of ultrasound diagnosis calcification for the thyroid cancer patients. Methods 180 patients with thyroid nodules were selected （ 120 cases with benign thyroid nodules and 60 cases with malignant thyroid nodules） in our hospital from February 2010 to June 2012; all cases were given routinely calcification ultrasound and angiography. Results Malignant thyroid nodules （60 cases） were mainly showed overall enhancement and the benign thyroid nodules （120 cases） with high peripheral ring enhancement. The AT values of the malignant thyroid nodules were significantly higher, while the PI values were significantly lower that compared had significantly differences （ P 〈 O. 05 ）. The overall calcification and micro calcifications rates of the malignant nodules patients were significantly. higher than the benign nodules（P 〈 0. 05 ）. Conclusion Uhrasound alcification and micro calcifications is favor of thyroid cancer, and ultrasound imaging applications is more helpful in the diagnosis of thyroid cancer.
