摘　　要：目的比较声触诊组织成像量化技术(VTIQ)与多层螺旋CT(MSCT)在甲状腺癌(TC)患者影像特征中的差异。方法选择118例甲状腺结节患者,根据病理诊断结果分为良性结节组(n=63)和TC组(n=55),均接受VTIQ、MSCT检查。比较两组患者的MSCT影像学特征、结节剪切波速度(SWV)值;多因素分析TC患者特征对VTIQ、MSCT诊断准确性的影响;分析VTIQ、MSCT对不同直径TC患者的诊断价值。结果TC组患者MSCT影像学特征(形态不规则、有边界断征、包膜分界不清楚、细颗粒钙化、磨玻璃样强化、增强扫描边界不清楚)比例均高于良性结节组,差异均有统计学意义(χ^(2)分别=6.74、62.46、14.48、56.70、4.61、41.18,P均<0.05)。TC组患者的SWV值高于良性结节组患者,差异有统计学意义(t=15.66,P<0.05)。logistic多因素分析结果显示,MSCT中边界断征、颗粒钙化、增强扫描边界不清楚征象及VTIQ中高SWV值为TC患者特异度影像学特征(OR分别=1.81、1.52、1.30、1.54,P均<0.05)。受试者工作特征(ROC)曲线结果显示,MSCT技术对直径>10 mm、≤10 mmTC患者的AUC均高于VTIQ技术(Z分别=4.27、4.03,P均<0.05),且两种诊断技术对直径>10 mmTC患者的诊断效能均高于直径≤10 mm患者(Z分别=3.68、3.54,P均<0.05)。结论VTIQ、MSCT在TC疾病鉴别中均有着特异度影像学特征,相较于VTIQ技术,MSCT技术诊断TC患者效能更高。Objective To compare the differences in imaging features between quantitative tissue imaging(VTIQ)and multi-slice spiral CT(MSCT)in patients with thyroid cancer(TC).Methods A total of 118 patients with thyroid nodules were selected and divided into benign nodule group(n=63)and TC group(n=55)based on pathological diagnosis results.Both accept VTIQ and MSCT techniques.MSCT imaging features and SWV values were compared between the two groups.The influence of the characteristics of TC patients on the diagnostic accuracy of VTIQ and MSCT was analyzed by multiple factors.The diagnostic value of VTIQ and MSCT in TC patients with different diameters was analyzed.Results The rate of MSCT imaging features(irregular morphology,boundary discontinuity,unclear capsule boundary,fine granular calcification,ground glass enhancement,and unclear enhanced scan boundary)in the TC group were higher than that in the benign nodule group(χ^(2)=6.74,62.46,14.48,56.70,4.61,41.18,P<0.05).The SWV value of patients in the TC group was higher than that of patients in the benign nodule group(t=15.66,P<0.05).The results of logistic multivariate analysis showed that the specific imaging features of TC patients were boundary discontinuity,granular calcification,unclear enhanced scan boundaries,and high SWV values in VTIQ in MSCT(OR=1.81,1.52,1.30,1.54,P<0.05).The receiver operating characteristic(ROC)curve results showed that the AUC of MSCT technology for patients with TC diameters greater than or equal to 10mm was higher than that of VTIQ technology(Z=4.27,4.03,P<0.05),and the diagnostic efficacy of both diagnostic techniques for patients with TC diameters greater than or equal to 10mm was higher than that for patients with TC diameters greater than or equal to 10mm(Z=3.68,3.54,P<0.05).Conclusion VTIQ and MSCT have specific imaging features in the differentiation of TC diseases.Compared with VTIQ technology,MSCT technology has higher diagnostic efficiency for TC patients.
