A Ho-166 labeled DTPA Derivative as a Potential Radiation Sourcefor Treatment of In-stent Restenosis

摘要

166Ho-DTPA bisamide derivative, DTPA-ATBA (3-amino-2,4,6-triiodobenzoic acid), is a potentialradiation source for vascular brachytherapy havingthe characteristic of CT contrast agent.Use of the complex for endovascular brachtherapy isa good alternative to see if the balloon has closecontact with the blood vessel wall for the delivery ofa sufficient radiation dose to the stenotic artery.
