摘　　要：目的比较超声及CT技术诊断甲状腺结节钙化的临床价值。方法选取我院2016年11月至2018年11月收治的137例甲状腺结节拟采取手术的患者,均于术前2周内行超声、CT检查,2种检查间隔1周内。以术后病理结果为基准,计算超声及CT诊断甲状腺结节的敏感度、特异度、符合率并进行比较,比较超声与CT对恶性结节与良性结节的粗钙化与微钙化检出率。结果 137例患者中101例(73.72%,共108枚)为恶性结节、36例(26.28%,共41枚)为良性结节。恶性结节直径(1.22±0.16)cm,良性结节直径(1.17±0.19)cm,差异无统计学意义(P>0.05)。149枚甲状腺结节中,超声共诊断出43枚良性结节与106枚恶性结节,CT诊断出47枚良性结节与102枚恶性结节。超声诊断甲状腺结节的敏感度与符合率分别为92.59%、91.95%,显著高于CT(P<0.05)。超声的恶性结节粗钙化与微钙化检出率及良性结节粗钙化检出率均显著高于CT(P<0.05)。结论超声诊断甲状腺结节钙化的检出率及对甲状腺结节良恶性的鉴别具有更高价值,可作为甲状腺结节诊断的首选方法 。Objective To compare the clinical value of ultrasound and CT in the diagnosis of thyroid nodule calcification.Methods The patients who underwent surgery for 137 cases of thyroid nodules admitted from November 2016 to November 1818 in our hospital were treated with ultrasound and CT within2 weeks before surgery.The two types of examinations were within 1 week.Based on postoperative pathological results,the sensitivity,specificity,and coincidence rate of ultrasound and CT diagnosis of thyroid nodules were calculated and compared.Ultrasound and CT were used to detect the crude calcification detection rate and microcalcification detection rate of malignant nodules and benign nodules.Results Of the 137 patients,101(73.72%,a total of 108) were malignant nodules,and 36(26.28%,a total of 41) were benign nodules.The diameter of malignant nodules was(1.22±0.16) cm,and the diameter of benign nodules was(1.17±0.19) cm.The difference was not statistically significant(P>0.05).Of the 149 thyroid nodules,43 benign nodules and 106 malignant nodules were diagnosed by ultrasound,and 47 benign nodules and 102 malignant nodules was diagnosed by CT.The sensitivity and coincidence rate of ultrasound diagnosis of thyroid nodules were 92.59% and 91.95%,respectively,which were significantly higher than CT(P<0.05).Ultrasound malignant nodules crude calcification and microcalcification detection rate and benign nodule coarse calcification detection rate was significantly higher than CT(P<0.05).Conclusion Ultrasound diagnosis of thyroid nodules calcification and the identification of benign and malignant thyroid nodules have a higher value,can be used as the first choice for the diagnosis of thyroid nodules.
