~(201)Tl心肌闪烁显像虽已广泛应用,但价格昂贵是其一大缺点.用回旋加速器可制成~(199)Tl的氯化铊等渗溶液,其半衰期是7.4小时,由于~(199)Tl的半衰期比~(201)Tl短,受检者的辐射剂量小,应用剂量可比~(201)Tl更大,也便于在运动后和药物治疗后重复检查.用~(199)Tl给59例经临床和其他检查方法确诊者(包括~(201)Tl和~(99m)Tc-PYP显像等)作心肌灌注闪烁显像,其中16例对照者、7例急性心肌梗塞、36例心绞痛病人.在运动高峰注射148～185MBq,6
~ (201) Tl myocardial scintigraphy has been widely used, but expensive is one of the major shortcomings of the cyclotron can be used to make ~ (199) Tl thallium chloride isotonic solution, the half-life of 7.4 hours, due to ~ (199) The half-life of Tl is shorter than ~ (201) Tl, and the dose of radiation is small and the applied dose can be larger than ~ (201) Tl, which also facilitates repeated examination after exercise and after drug treatment. Tl to 59 patients diagnosed by clinical and other examination methods (including ~ (201) Tl and ~ (99m) Tc-PYP imaging, etc.) for myocardial perfusion scintigraphy, including 16 cases of control, 7 cases of acute myocardial infarction, 36 patients with angina pectoris were injected at peak exercise at 148 ~ 185MBq, 6
