本文讨论使用四种适合于肿瘤扫描的放射性同位素,即~(75)硒、~(67)镓、~(111)铟及~(32)磷,着重述及对头颈部恶性肿瘤的诊断。作者报导后二者的个人经验。在头颈部恶性肿瘤中,用铁(离子转运)蛋白(朊)标记~(111)铟扫描时,10例中有7例(70％)为阳性。用~(32)磷扫描时,10例口腔肿瘤及7例皮肤恶性病变均为阳性(100％),7例颈部恶性肿块,3例(43％)为阳性。 This article discusses the use of four radioisotopes that are suitable for oncological scanning, namely ~(75)selenium, ~(67) helium, ~(111)indium, and ~(32)phosphorus, highlighting the diagnosis of head and neck malignancy. The author reports on the personal experience of the latter two. In head and neck malignancies, 7 (70%) of the 10 cases were positive with the (111) indium labelled with the iron (ion transport) protein (Tb). When scanning with ~(32)P, 10 cases of oral tumors and 7 cases of malignant skin lesions were positive (100%), 7 cases of malignant neck lesions, and 3 cases (43%) were positive.
