目的 评价SPECT/CT亲肿瘤融合显像对甲状腺结节良恶性鉴别的临床价值.方法 106例甲状腺结节患者静注99TCm-MIBI后行早期(30 min)及延迟(120 min)平面显像,在30 min时进行SPECT/CT融合显像.显像结果与手术病理结果相对照.结果 106例患者中良性病变82例(77.36％),恶性病变24例(22.64％),SPECT/CT融合显像的敏感度为70.83％;特异性为80.49％；诊断准确度为78.30％.结论 SPECT/CT亲肿瘤融合显像对甲状腺结节的良恶性鉴别有重要价值.%Objective To evaluate the clinical value of SPECT/CT imaging to identify benign and malignant thyroid nodules. Methods One hundred and six patients with thyroid nodule received early (30 min) and delayed (120 min) planar imaging as well as SPECT/CT fusion imaging (30 min) after intravenous 99TCm-MIBI. The imaging results were compared the surgical and pathological results. Results Eighty-two patients were found to be benign lesions (77.3%) and 24 were malignant lesions (22.6%). The sensitivity, specificity and the accuracy of SPECT/CT fusion imaging were 70.8%, 80.4%, 78.3%, respectively. Conclusion SPECT/CT fusion imaging has great significance in the identification of benign and malignant thyroid nodule.
