Description

In order to screen out an ideal radioactive agent for preventing the restenosis after PTCA (Percutaneous Transluminal Coronary Angioplasty), Na188ReO4, 188Re-DTPA and 188Re-MAG3 are injected into ICR mice and SD rats to compare the biodistribution and excretion. The experimental data show that the blood clearance of 188Re-MAG3 is much faster, and the uptake in tissues is obviously lower than Na188ReO4 and 188Re-DTPA. Ar 2 h after injection, 77.28% of injection dose of 188Re-MAG3 is excreted from urine, whereas less than 50% for Na188ReO4 and 188Re-DTPA. So, 188Re-MAG3 is a better candidate for balloon dilation providing uniform endovascular irradiation following PTCA for restenosis therapy. (authors)
