Question
I had a contrast enhanced Head CT and a no contrast CT (done at different times). I'm wondering if the use of contrast medium increases scanning time and radiation dose. Because, when I had the contrast CT I was there longer that the CT that didn't have the contrast. Thank you

Answer
Not by itself but there may have been details that they wanted to have a closer look at. Longer time in the machine does mean more radiation exposure but everything is done to keep that at a minimum.
