目的 探讨99Tcm-MIBI亲肿瘤延迟断层显像在肺部占位病灶中的诊断价值.方法 对28例肺部占位患者静脉注射740 MBq99Tcm-MIBI后1 h行延迟断层显像,以占位病灶(T)/对侧相应部位或邻近正常组织(N)的摄取比值T/N＞1.31为恶性病变标准对肺部占位病灶进行良、恶性判断.结果 肺占位在良性占位组显像剂浓聚多数轻度增强,恶性占位组多数明显增强.肺占位诊断恶性病灶的灵敏度为76.9%,特异度为86.7%,假阳性为13.3%,假阴性为23.1%.结论 99Tcm-MIBI亲肿瘤延迟断层显像以其无创、灵敏、图像质量及特异性较高的优点,可作为在肺占位病灶良、恶性鉴别诊断的重要辅助检查手段.
目的 探討99Tcm-MIBI親腫瘤延遲斷層顯像在肺部佔位病竈中的診斷價值.方法 對28例肺部佔位患者靜脈註射740 MBq99Tcm-MIBI後1 h行延遲斷層顯像,以佔位病竈(T)/對側相應部位或鄰近正常組織(N)的攝取比值T/N＞1.31為噁性病變標準對肺部佔位病竈進行良、噁性判斷.結果 肺佔位在良性佔位組顯像劑濃聚多數輕度增彊,噁性佔位組多數明顯增彊.肺佔位診斷噁性病竈的靈敏度為76.9%,特異度為86.7%,假暘性為13.3%,假陰性為23.1%.結論 99Tcm-MIBI親腫瘤延遲斷層顯像以其無創、靈敏、圖像質量及特異性較高的優點,可作為在肺佔位病竈良、噁性鑒彆診斷的重要輔助檢查手段.

Objective To investigate the diagnotic value of tumor positive delay tomogram imaging with 99Tcm-methoxyisobutylisonitrile(MIBI ) for pulmonary neoplasm. Methods Twenty-eight cases pulmonary neoplasms traded by 99Tcm-MIBI imaging,then performed tornogram imaging after 1h. By the uptake ratio value exceeding 1.31 between pulmonary neoplasm( T )and normal tissue on the opposite side or vicinity tissue (N),benign or malignant was diagnosted. Results The malignant pulmonary neoplasm had abnormal high uptake, but benign pulmonary neoplasm had light uptake. The sensitivity and specificity of 99Tcm-MIBI imaging for the malignant pulmonary neoplasm were 76.9% and 86.7% respectively, the false positive and false negative rate were 13.3% and 23.1% respectively. Conclusions Tumor positive delay tomogram imaging with 99Tcm-MIBI for pulmonary neoplasm is an important detection in differentiating benign and malignant, it has high sensitivity, specificity, picture quanlity and no wound again.
