摘要
目的评价低剂量SPECT/CT在鉴别甲状腺良恶性结节中的增益价值。方法收集触诊/彩色多普勒超声考虑甲状腺结节患者41例,分别行^(99)Tc^(m)O_(4)-平面显像和低剂量SPECT/CT融合显像,以病理结果为金标准,比较2者诊断效能。结果低剂量SPECT/CT融合显像诊断甲状腺结节良恶性的灵敏度、特异度、准确率及受试者工作特征(ROC)曲线下面积(AUC)分别为61.90%、53.33%、63.41%和0.64;均高于^(99)Tc^(m)O_(4)-平面显像的19.05%、45.00%、31.70%和0.32(P均<0.05)。结论低剂量SPECT/CT对恶性甲状腺结节的诊断效能优于^(99)Tc^(m)O_(4)-平面显像。
Objective To evaluate the gain value of low-dose SPECT/CT in differential diagnosis of benign and malignant thyroid nodules.Methods Totally 41 patients with thyroid nodule considered by palpation/color Doppler ultrasonography were prospectively collected.^(99)Tc^(m)O_(4)-plane imaging,low-dose SPECT/CT fusion imaging were performed,respectively.Results The sensitivity,specificity,accuracy and area under the receiver operating characteristic(ROC)curve(AUC)of low-dose SPECT/CT fusion imaging in differential diagnosis of benign and malignant thyroid nodules were 61.90%,53.33%,63.41%and 0.64,respectively;which were higher than those of planar imaging of 19.05%,45.00%,31.70%and 0.32(all P<0.05).Conclusion Low-dose SPECT/CT is better than^(99)Tc^(m)O_(4)-planar imaging in diagnosis of malignant thyroid nodule.
