Fifteen patients with 21 subdural effusions were investigated both with transmission computer assisted tomography (CAT) and positron emission tomography (PET). The tracer in the emission studies was 68Ga-EDTA. Twelve lesions were visualized both with CAT and PET. Five lesions that were negative or doubtful on CAT were visualized with PET, whereas four lesions negative or doubtful on PET were demonstrated by CAT. The two methods complement each other due to the fact that they are based on different mechanisms: CAT mainly on attenuation of the fluid collection. PET on isotope accumulation, particularly in the hematoma membranes.
对15例患有21处硬膜下积液的患者进行了透射计算机断层扫描（CAT）和正电子发射断层扫描（PET）检查。发射研究中的示踪剂为68Ga-EDTA。12处病变在CAT和PET检查中均显影。5处在CAT检查中呈阴性或可疑的病变在PET检查中显影，而4处在PET检查中呈阴性或可疑的病变由CAT检查显示。这两种方法相互补充，因为它们基于不同的机制：CAT主要基于液体聚集的衰减，PET基于同位素聚集，特别是在血肿膜中。
