目的 :探讨99m锝 甲氧基异丁基异腈 (99m Tc MIBI)单光子发射型计算机断层显像仪 (SPECT)核素显像对肺癌纵隔淋巴结转移的价值 ,并与CT进行对比。方法 :原发性肺癌 2 2例 ,病人在手术前同时做了CT和99mTc MIBISPECT显像 ,术后进行了病理检查。结果 :99m Tc MIBISPECT诊断的灵敏性 63 .6% ,特异性 81.8% ,准确性 72 .7%。CT灵敏性 2 7.2 % ,特异性 72 .7% ,准确性 67.7%。结论 :本研究发现99m Tc MIBISPECT核素显像技术在纵隔淋巴结转移检查方面比CT更灵敏、更精确 ,今后应该在应用99m Tc MIBISPECT寻找淋巴结转移方面 ,如乳腺癌、甲状腺癌、头颈部肿瘤等更加广泛的研究 ,为制定肿瘤治疗方案提供帮助
Objective: To investigate the value of 99m Tc MIBI single photon emission computed tomography (SPECT) radionuclide imaging in mediastinal lymph node metastasis of lung cancer and to compare with CT. Methods: Twenty-two patients with primary lung cancer underwent both CT and 99mTc MIBISPECT imaging before the operation. Pathological examination was performed after operation. Results: The diagnostic sensitivity of 99m Tc MIBISPECT was 63.6%, the specificity was 81.8% and the accuracy was 72.7%. CT sensitivity 2 7.2%, specificity 72.7%, accuracy 67.7%. Conclusion: This study found 99m Tc MIBISPECT radionuclide imaging in mediastinal lymph node metastases more sensitive than CT, more accurate in the future should be used 99m Tc MIBISPECT looking for lymph node metastasis, such as breast cancer, thyroid cancer, head and neck cancer More extensive research, for the development of cancer treatment programs to provide help
