摘要

民國68年12月至69年明之半年間，本科有五百病例進行碘－131攝取檢查。吾人探討其服藥後二小時所作之攝取率測試結果的臨床應用價值。吾人發現，僅有百分之0.6的病例有助於臨床診出甲狀腺機能亢進之用。而且，這些病人之臨床上業已有充分之徵候顯示病人患有甲狀腺機能亢進而必須同時進行他項檢查。由此觀之，爲此百分之0.6之病人，每年耗費50小時之技術員操作時間，實屬不必要之浪費。 吾人之結論爲終止該項檢査工作。

We analyzed the 2-hour thyroid I-131 uptake values in 500 cases performed in the Division of Nuclear Medicine, Department of Radiology in our hospital. There are only 15 cases(3%) had the 2-hour value higher than the 24-hour value. Twelve cases among them had both 2-hour and 24-hour values in the hyper-function range. The other three (0.6%) had normal or low 24-hour value. All these three patients had been treated as hyperthyroidism. The procedure of 2-hour uptake test needs nearly 3 minutes for each patient. It takes 50 technician-hour every year(around 1000 studies a year) for the detection of hyperthyroidism in the only 0.6% of the patients in our lab. Thus we recommend discontinuing the 2-hour uptake test.
