We can inject these dyes into the bloodstream, so that when we do a new vessel and we bypass a blockage on the heart, we can see if we actually made the connection, before we close that patient back up again -- something that we haven't been able to do We can light up tumors like this kidney tumor, so that you can exactly see where the boundary is between the kidney tumor and the kidney you want to leave behind,
我们可以把这些染料注射到血流中， 这样我们可以为心脏堵塞的病人 搭建血管旁路。 在我们最后为病人缝合之前， 我们能够看到是否真正搭建了连接。 以前由于没有放射技术， 有些事我们还是做不到。 现在我们能使肿瘤发光， 就象这个肾肿瘤， 你可以真实地看到肿瘤的边界， 这个肾你想留下。
