I know that some contract create headache and some patient allergy
This is why we have 2 contract media
This is why the doctor prescribe different contract media follow his assessment
My suggestion after discussed with JM; he told me he ordered to use 2 contrast medias suppliers since 2 years ago. I think we are better to use at least 2 contrast medias suppliers in one site.
I have no problem to order more than 2 contrast media, just to notice that one is expensive than normal 14 THB/ bottle. Once both of you agreed to use 2 that fine.
