We investigate biodistribution of gallium-labeled hydroxyethylidenediphosphonic acid ( 68 Ga-HEDP) and diethylenetriaminepentakis(methylenephosphonic acid) ( 68 Ga-DTPMP) in intact Wistar rats. It was shown that 68 Ga-DTPMP accumulated mainly in the bone tissue providing high femur/blood and femur/muscle ratios and had high stability in vivo. In contrast, 68 Ga-HEDP was characterized by low stability and high uptake of radioactivity in blood throughout the study. So 68 Ga-DTPMP can be considered as a new prospective radiotracer in oncology for imaging bone tissue metastasis by positron emission tomography.

基于膦酸和镓68的新型寻骨化合物的生物分布实验研究

我们研究了镓标记的羟亚乙基二膦酸 (68 Ga-HEDP) 和二亚乙基三胺五(亚甲基膦酸) (68 Ga-DTPMP) 在完整 Wistar 大鼠中的生物分布。结果表明,68 Ga-DTPMP 主要在骨组织中积累,提供高股骨/血液和股骨/肌肉比率,并且在体内具有高稳定性。相比之下,在整个研究过程中,68 Ga-HEDP 的特点是稳定性低,血液中的放射性吸收率高。因此 68 Ga-DTPMP 可以被认为是肿瘤学中一种新的前瞻性放射性示踪剂,用于通过正电子发射断层扫描对骨组织转移进行成像。
