至今,在慢性失血及急性下消化道出血病人中,即使应用内窥镜和血管造影,仍难以成功地检出胃肠道出血病灶的部位。作者用锝标记的自体红细胞(TcRBC)检测胃肠道出血部位,并与其它诊断方法作比较。
To date, in patients with chronic blood loss and acute lower gastrointestinal bleeding, it is difficult to successfully detect the site of the gastrointestinal bleeding lesion even with the use of endoscopy and angiography. The authors used technetium-labeled autologous red blood cells (TcRBC) to detect gastrointestinal bleeding sites and compared them with other diagnostic methods.
