~(67)镓已广泛地用于检查原因不明发热病人、肿瘤分期及某些其它疾病的识别或随访。注射~(67)镓最初24小时经肾排泄约12～30%,一般认为注射48小时后仍见尿路吸收则是异常现象。此项研究是回顾性评价~(67)镓延迟肾浓集的发生率及其可能原因。材料与方法作者自1981～1982年连续应用~(67)镓显象500例,男373人,女127人,年龄为18个月～78岁。成人静注枸橼酸~(67)镓4～5毫居里,儿童剂量按体重递减。使用备有高能平行孔准直仪大视野照相机,以及双信道或三信道脉冲高分析仪。根据48或72小时显象的肾摄取度分级如下:0级为本底放射性;Ⅰ级大于本底放射性,小于脊柱的摄取度;Ⅱ级接近脊柱摄取,小于肝摄取;Ⅲ级等于肝摄取;Ⅳ级大于肝摄取。
~ (67) Gallium has been widely used in the identification of patients with unexplained fever, tumor staging and some other diseases or follow-up. Injection ~ (67) gallium by the first 24 hours of renal excretion of about 12 to 30%, generally believed that 48 hours after injection of urine is still seen abnormal absorption. This study is to retrospectively evaluate the incidence of ~ (67) gallium delayed renal accumulation and its possible causes. Materials and Methods From 1981 to 1982, the authors applied consecutively ~ (67) gallium scintigraphy in 500 cases, including 373 males and 127 females, aged from 18 months to 78 years old. Adult intravenous citrate ~ (67) gallium 4 ~ 5 millicuries, children’s dose decreased by body weight. Use a high-field camera with a high-energy parallel hole collimator and a two- or three-channel pulse height analyzer. Levels of renal uptake at 48 or 72 hours were graded as follows: Grade 0 was background radioactivity; Grade I was greater than background radioactivity and less than spinal uptake; Grade II was close to spinal uptake and less than liver uptake; Grade III was equal to liver uptake; Grade IV is greater than liver uptake.
