The gastric mucosa blood flow was investigated using the 99mTc clearance. Besides the clearance the "R" ratio, total radioactivity of the gastric juice and the volume of gastric juice (ml/15 min) were also investigated. The main characteristics of the method are its reproducibility and the parallelism existing between: clearance, the "R" ratio and total radioactivity. The parameters investigated reach a maximum 30-45 min after administration of 99mTc; consequently, to evaluate gastric blood flow, it is sufficient to determine the parameters at this time interval. The 99mTc clearance represents an accessible method for the evaluation blood circulation in the gastric mucosa.
采用99mTc清除率研究胃黏膜血流量。除清除率外，还研究了“R”比值、胃液总放射性和胃液体积（毫升/15分钟）。该方法的主要特点是其可重复性以及清除率、“R”比值和总放射性之间存在的平行关系。给药99mTc后30 - 45分钟，所研究的参数达到最大值；因此，为评估胃血流量，在该时间间隔测定参数就足够了。99mTc清除率是评估胃黏膜血液循环的一种可行方法。
