Abstract

The mechanism of 201Tl chloride accumulation is unclear in thyroid gland and thyroid tumor. This report examines 108 patients that received thyroid scintigraphy examinations with both 201Tl chloride and sodium 131I. The patients were diagnosed clinically and histologically whenever possible. The ROI were obtained by subtraction imaging with both isotopes and by subtraction positive and negative areas of imaging. Dynamic curves were obtained for 201Tl chloride per square unit of each ROI. The dynamic curve in the radioiodide-accumulated area was examined. The data indicate that the clearance rate of 201Tl chloride (T15) was correlated with the sodium 131I uptake rate at 24 h (r = 0.70).

摘要

氯化铊在甲状腺及甲状腺肿瘤中的蓄积机制尚不清楚。本报告研究了108例接受过氯化铊和131I 化钠甲状腺闪烁扫描检查的患者。尽可能对患者进行了临床和组织学诊断。通过两种同位素的减影成像以及成像的正负区域相减来获取感兴趣区（ROI）。为每个ROI的每平方单位获取氯化铊的动态曲线。对放射性碘蓄积区域的动态曲线进行了研究。数据表明，氯化铊的清除率（T15）与24小时时131I 化钠的摄取率相关（r = 0.70）。
