作者对97例有组织学证实的恶性肿瘤患者用~(201)TI进行了显像检查(肺癌56例、乳腺癌26例、恶性淋巴瘤15例)。方法为:静脉注射~(201)TlCl 75MBq并用10ml生理盐水冲洗注入,收集方法为每5秒一帧收集5分钟,用64×64的矩阵;每30秒一帧收集55分钟,用128×128的矩阵;用10分钟收一帧注药后4小时的静态像。结果:在被研究的97例患者中,85例显像异常(48例肺癌、24例乳腺癌、13例淋巴瘤)。作者发现,静脉注射~(201)Tl后,肿瘤很快摄取,在整组研究病例中,从注药到肿瘤放射性峰值时间为8～20分钟,在被研究的各类肿瘤之间,肿瘤放射性达峰值的时间无显著差异。存在于肿瘤中的放射性在注药
The authors performed imaging examinations on 97 patients with histologically proven malignancy (~ 56 with lung cancer, 26 with breast cancer and 15 with malignant lymphoma) using ~ (201) TI. The procedure consisted of iv injection of ~ (201) TlCl 75 MBq and infusion with 10 ml of saline for a 5 minute collection every 5 seconds for a 64 × 64 matrix; 55 minutes for a 30 second frame, 128 × 128 Of the matrix; with 10 minutes to receive a frame 4 hours after the injection of static images. RESULTS: Of the 97 patients studied, 85 were imaging abnormalities (48 with lung cancer, 24 with breast cancer and 13 with lymphoma). The authors found that tumors were rapidly taken up after ~ (201) Tl iv injection. In the entire study population, radioactive peak time from injection to tumor was 8-20 minutes. Between the various types of tumors studied, tumor radioactivity There was no significant difference in peak time. Radioactivity present in the tumor is injected
