目的 :用 1 2 3 I- epidepride SPECT显像对丘脑和颞叶皮层进行 D2 受体定量分析 ,并评估两次实验的重复性。方法 :对 10名健康志愿者 (4男 ,6女 ,年龄 19～ 46岁 )以弹丸加恒速静注模式 (弹丸 /静注 =6 h;静注时间 =9h)进行两次 SPECT研究 (间隔 2～ 2 6 d)。在注射后 3、4
OBJECTIVE: To quantify D2 receptors in the thalamus and temporal cortex with 123 2 I-epidepride SPECT imaging and assess the reproducibility of the two experiments. METHODS: Ten SPECT studies (10 males, 6 females, aged 19-46 years old) were performed with progestational and intravenous bolus injection (bolus / intravenous injection = 6 h; intravenous injection = 9 h) Interval 2 ~ 2 6 d). 3,4 after injection
