摘　　要：目的观察CT增强扫描结合后处理技术对良恶性甲状腺病变的诊断价值。方法将本院2018年9月到2022年9月期间收集的134例经病理证实的甲状腺结节患者作为研究对象,所有患者均接受了CT增强扫描结合后处理技术,探讨该技术在甲状腺良恶性病变诊断中的价值,并比较不同患者间图像特征、平扫期CT值、动脉期CT值和静脉期CT值差异,同时关注病灶内钙化情况。结果134例甲状腺结节患者中,病理检测恶性74例,良性60例,螺旋CT增强诊断恶性76例,良性58例,以病理学检测为金标准,螺旋CT增强扫描诊断甲状腺良恶性结节敏感度为97.30%,特异性为93.33%,准确率为95.52%;恶性组甲状腺结节不规则形态、边界模糊及肿大淋巴结比例显著高于良性组(P<0.05);两组间平扫期CT值、动脉期CT值以及静脉期CT值差异比较无统计学意义(P>0.05);恶性组有钙化点比例显著高于良性组(P<0.05)。结论螺旋CT增强扫描及后处理技术在甲状腺良恶性结节鉴别诊断中具有重要意义,图像特征及钙化特征显示较为明显,为临床诊治提供重要参考依据。Objective To observe the diagnostic value of CT enhanced scanning combined with post-processing technology on benign and malignant thyroid lesions.Methods 134 patients with thyroid nodules confirmed by pathology in the hospital were selected from September 2018 to September 2022 as the study subjects.All patients received CT enhanced scanning combined with post-processing technology,and the value of this technology in diagnosing benign and malignant thyroid nodules was explored.The image features,CT value in plain scan phase,CT value in arterial phase,and CT value in venous phase were compared among the patients,and the lesion calcification was paid attention to.Results Among 134 patients with thyroid nodules,74 cases were malignant and 60 cases were benign by pathological examination,and 76 cases were malignant and 58 cases were benign by dual-phase enhanced spiral CT scanning.The sensitivity,specificity and accuracy rate of dual-phase enhanced spiral CT scanning in the diagnosis of benign and malignant thyroid nodules were 97.30%,93.33%and 95.52%by using pathological examination as the gold standard.The proportions of irregular shape,blurred boundary and enlarged lymph nodes in malignant group were significantly higher than those in benign group(P<0.05).There were no statistically significant differences in CT value in plain scan phase,CT value in arterial phase and CT value in venous phase between the two groups(P>0.05).The proportion of calcification point in malignant group was significantly higher than that in benign group(P<0.05).Conclusion Spiral CT enhanced scanning and post-processing technology are of great significance in the differential diagnosis of benign and malignant thyroid nodules,and the image features and calcification characteristics are more obvious,which can provide important basis for clinical diagnosis and treatment.
