【摘要】 目的探讨钙化在CT诊断和鉴别甲状腺结节病变中的价值。方法回顾性分析140例甲状腺结节病例,全部经螺旋CT检查并穿刺活检或手术病理证实(良性病变72例,恶性病变68例)的临床资料。结果 140例甲状腺结节中共检出钙化66例(47.1%),而甲状腺恶性病变中钙化的检出率较甲状腺良性病变的高(61.8%vs 33.3%,P<0.01)。检出钙化的66例甲状腺病变中,微小钙化的检出率为45.5%,而甲状腺恶性病变中微小钙化的检出率较甲状腺良性病变的高(54.8%vs 29.2%,P<0.05)。检出钙化的66例甲状腺病变中,<45岁的有25例,≥45岁的有41例,其在甲状腺良、恶性病变患者中的分布差异有统计学意义(P<0.05)。结论甲状腺CT检查显示钙化提示甲状腺恶性病变,而有微小钙化或为年龄<45岁则高度提示甲状腺恶性病变,应引起重视。更多还原

【Abstract】 Objective To clarify the value of calcification in CT diagnosis and differentiating benign and malignant thyroid lesions. Methods One hundred forty patients with thyroid nodules were selected, including 72 patients with benign thyroid nodules and 68 patients with malignant thyroid nodules. All of them had pathologic diagnosis. Result The rate of calcification in the benign and malignant thyroid nodules had strong statistical significance(P<0.01). Microcalcification had statistical significance in differentiating malignant thyroid nodules(P<0.05).There was significant difference between the thyroid nodules accompanying with calcification in age groups, but not in sex groups. Conclusion The microcalcification was highly suggestive of malignant thyroid nodules and we should pay attention to the young patients who had thyroid nodules accompanying with calcification.更多还原
