各种CT征象联合应用在甲状腺良恶性结节诊断中的价值分析

目的：探究各种CT征象联合应用在甲状腺良恶性结节诊断中的价值。方法方便选择2015年1月＿2016年8月期间于邳州市中医院接受检查的80例甲状腺良恶性结节患者为研究对象。将结节强化程度分为高强化与等低强化结节,将高强化CT征象对于良性结节和腺瘤样结节诊断的特异性,敏感性阳性与阴性预测值与准确性进行比较。结果高强化良性结节22个,恶性结节1个；等低强化良性阶级79个,恶性结节43个。高度强化于甲状腺良恶性诊断中存在不同,组间数据差异有统计学意义,P﹤0.05,高度强化常见于良性结节中,等低强化常见于恶性结节中。高度强化对于良性结节存在高度特异性与阳性预测值,对于腺瘤样结节存在高度敏感性与特异性、准确性以及阴性预测值。结论通过对于良性甲状腺结节的高阳性预测值与特异性,和腺瘤样结节的高敏感性、阴性预测值、准确性、特异性的研究分析；得到的结果证实强化CT征象为甲状腺恶性/良性结节甄别的重要依据。

All Kinds of CT Signs Combined Application Value in the Diagnosis of Be-nign and Malignant Thyroid Nodules were Analyzed

Objective To explore a variety of CT signs of joint application value in the diagnosis of benign and malignant thyroid nodules. Methods Convenient choose January 2015 to August 2016 to pizhou undergoes examination of 80 patients with benign and malignant thyroid nodules as the research object. Nodules enhancement degree can be divided into obvi-ous enhancement nodules and low enhancement nodules , such as high enhancement CT signs for benign nodules and nod-ule diagnosis of adenoma samples specificity, sensitivity of positive and negative predictive value and accuracy of the com-parison. Results Highly fortified benign nodules 22, 1 malignant nodules; Such as low strengthen the benign class 79, 43 malignant nodules. Highly fortified in thyroid benign and malignant diagnosis is different, the data statistical differences be-tween groups(P<0.05 Conclusion Through to the high positive predictive value and specificities of benign thyroid nodules, and sample adenoma nodules of high sensitivity, negative predictive value, accuracy and specificity of research. The results confirmed that the enhanced CT signs is to identify the important basis of malignant and benign thyroid nodules.
