在北美放射学会年会上,一些研究人员指出,应用镓和铟标记白细胞的放射性核素扫描对鉴定发热艾滋病患者各种机会致病菌性感染有参考价值。芝加哥西北大学的一项研究发现,在检查卡氏肺囊虫(PCP)性肺炎和鸟型结核分支杆菌(MAI)性结核时,Ga-67的敏感性超过90％.对42名艾滋病患者进行的52次扫描中,镓鉴别PCP的总敏感性为95％,这些病人大多数有发热和/或急性呼吸道症状。更重要的是,镓扫描可在胸部X线证实之前约9天查出PCP感染,而且查出的病人中有2/3最初X检查呈阴线性或不明确.在这些病人中观察到的最普遍的镓扫描型是弥漫性肺活性的图型.共23名病人显示此图型.
At the annual meeting of the North American Society of Radiology, some researchers pointed out that using radionuclide scans of gallium and indium-labeled leukocytes is valuable in identifying opportunistic infections of various kinds in opportunistic AIDS patients. A study by Northwestern University in Chicago found that the sensitivity of Ga-67 is over 90% when examining Pneumocystis carinii pneumonia (Pneumocystis carinii) and Mycobacterium avium (MAI) tuberculosis.42 AIDS patients Of the 52 scans, the total sensitivity of gallium in differentiating PCP was 95%. Most of these patients had fever and / or acute respiratory symptoms. More importantly, gallium scintigraphy can detect PCP infection about 9 days prior to chest X-ray confirmed, and 2/3 of the patients initially identified were negative or ambiguous in the initial X. Most observed among these patients A common type of gallium scan is a pattern of diffuse lung activity. A total of 23 patients showed this pattern.
