以往检查肝恶性肿瘤常用的放射性制剂为标记的胶体,其结果不能揭示病变的性质,只能闸明器官的局灶损伤。为诊断转移性肝癌,除使用标记的胶体外,还采用~(75)硒-蛋氨酸。关于~(75)硒-蛋氨酸诊断肝肿瘤的报道不多,其临床价值说法不一。本文用双标记核素进行连续肝扫描,当~(113m)In胶体肝扫描出现缺损区时,用~(75)硒-蛋氨酸再进行肝扫描.~(113m)In 注射剂量为37MBq、~(75)硒-蛋氨酸为9.25MBq.在注射后的30分钟1、2及24小时进行扫描.根据它们的能量选择相应的准置器.
In the past, radioactive agents commonly used for the examination of hepatic malignancies were marked colloids, and the results could not reveal the nature of the lesions. To diagnose metastatic liver cancer, ~(75)selen-methionine was used in addition to the labeled gel. There are few reports on the diagnosis of liver tumors by ~(75)selenyl-methionine, and their clinical values are not consistent. In this study, continuous hepatic scans were performed with dual-labeled nuclide. When ~(113m)In colloidal hepatic scan was found in the defect zone, hepatic scan was performed with ~(75)selen-methionine. The dose of ~(113m)In was 37MBq, ~( 75) Selenium-methionine was 9.25MBq. Scans were taken at 30 minutes 1, 2, and 24 hours after injection. Select the appropriate aligner based on their energy.
