目的探讨99mTc-甲氧异丁基异睛(99mTc-MIBI)肺亲肿瘤显像与多层螺旋CT联合诊断孤立性肺结节中的临床价值。方法对50例X线胸片发现孤立性肺结节的患者均进行99mTc-MIBI肺肿瘤显像、多层螺旋CT扫描,将结果与手术及病理结果对照,分别及联合计算两种方法鉴别诊断孤立性肺结节中的灵敏度、特异性、准确性。结果 99mTc-MIBI亲肿瘤显像诊断肺结节的灵敏度、特异性、准确性分别为76.9%,81.8%,78.0%;多层螺旋CT扫描为76.9%,72.7%,76.0%。两种检测方法联合运用为94.9%、90.9%和94.0%。结论 99mTc-MIBI肺部亲肿瘤显像联合多层螺旋CT检测提高了对孤立性肺结节的诊断价值。
Objective To investigate the clinical value of 99mTc-methoxyisobutyryl (99mTc-MIBI) lung tumor imaging combined with multi-slice spiral CT in the diagnosis of solitary pulmonary nodules. Methods Fifty patients with solitary pulmonary nodules who had solitary pulmonary nodules were examined by 99mTc-MIBI lung tumor imaging and multi-slice spiral CT. The results were compared with the results of surgery and pathology, respectively, and the two methods were combined to calculate the differential diagnosis Sensitivity, specificity and accuracy in isolated pulmonary nodules. Results The sensitivity, specificity and accuracy of 99mTc-MIBI tumor imaging in diagnosis of pulmonary nodules were 76.9%, 81.8% and 78.0%, respectively. The multi-slice spiral CT was 76.9%, 72.7% and 76.0% respectively. The combined use of the two assays was 94.9%, 90.9% and 94.0%. Conclusion 99mTc-MIBI pulmonary tumor imaging combined with multi-slice spiral CT improves the diagnosis of solitary pulmonary nodules.
