SPECT核素显像鉴别诊断肺部良恶性病变

SPECT Radionuclide Imaging in the Differential Diagnosis of Malignant and Benign Lung Lesions

报告48例^(99m)TC-GH 肺三相显像与手术病理结果对照研究,探讨SPECT(单光子发射计算机断层扫描)核素显像鉴别诊断肺部良恶性病变的应用价值。结果表明^(99m)TC-GH 肺三相显像对肺部恶性肿瘤的灵敏度89.2%,特异性90.9%,准确性89.6%;核素病灶浓聚程度(?)小细胞未分化癌最高,鳞癌次之,腺癌最少。我们认为SPECT 核素肺三相显像可作为胸部x 线平片可疑肺癌患者术前无创伤性诊断方法。

A comparative study of preoperative ^(99m)TC-GH three-phase imaging of lungtumors and their postoperative pathological examination in 48 cases was reported,in orderto evaluate the value of SPECT radionuclide imaging in differential diagnosis between malig-nant and benign lung lesions.The results showed that the sensitivity,Specificity and accuracyof ^(99m)TC-GH three phase imaging in malignant lung tumors were 89.2%,90.9% and 89.6%,respectively.The degree or intensity of radionuclide uptake in the diseased region washighest in Small cell lung cancer,the Second was in Squamous cell lung Cancer and thethird was in adenocarcinoma.The authors considered that SPECT radionuclide lung three-phase aseimaging is a noninvasive and specifie method in diagnosing those cases of lungcancer as suspected on the ordinary X-ray chest film(?) before operation.
