My Dr. ordered a CT chest scan w contrast bc of my peripheral neuropathy. She also ordered a sinus ct (although I am not sure why) which was done at the same time. The tech did two passes on my chest without telling me and now I am concerned about two things: one is the amount of radiation I have been exposed to this year. I am 57 and in the last 9 months I have had a mammogram and two chest X-rays plus this CT. I don t know whether to be upset with this new doctor or not. I asked for he lowest setting and one pass and they looked at me like I was nuts. Also, I feel like my neuropathy is worse since the scan so in case it was a reaction to the dye I ve been pushing water ( which they did not tell me to do at the center after I left) and eating cilantro (I know, Iknow, but Im flipping out). Is this the equivalent of having three ct scans in one day? Is my dr. over testing?
