Anyone else have allergic reaction to scan contrast dye?

Hi Vicky
Just wondering if there is only ONE type of contrast available for ct scans in the States? For many other procedures there are a number of similar products that do the same job but may not cause the same reaction. Would your radiologist be able to research this for you? The reason I ask is that I have had ct scans at two different hospitals here in England but both used different contrast.
Hope this helps, I know some things are done differently across the pond.
