在五个月的时间内，对 6 名患者研究了地塞米松对脑肿瘤中碘酞酸盐和 99mTc 高锝酸盐积累的影响。在地塞米松治疗之前和期间，对患者进行 X 射线（透射）计算机断层扫描 (CT) 和放射性核素（发射）计算机断层扫描 (RCT) 检查。狭窄减少了两种药物的积累程度，但没有改变它们分布的边界。
The effect of dexamethasone on the accumulation of iothalamate and 99mTc pertechnetate in cerebral tumors was investigated in 6 patients over a five-month period. Patients were examined by x-ray (transmission) computed tomography (CT) and by radionuclide (emission) computed tomography (RCT) prior to and during a course of dexamethasone therapy. Stenosis diminished the degree of accumulation of both agents but did not change the boundaries of their distribution.
