Shadow during CT scan

User Profile
Hi,

I recently had another CT scan after one a year ago for a small 3mm nodule found incidently after a car accident. I was a heavy smoker for 17 years - 2 packs a day. On the most recent CT scan the Dr. said it hasn't "really" changed but there is a shadow. She says it probably from breathing during the scan but I know that I didn't move. She has me going back in 3 months instead of a year. Could this moving be true? I couldn't find examples of this doing a search. I am OK with the answer as I have had multiple problems including a liver transplant,for which I take immunosuppresants,and bullous disease with multiple lung collapses for which I had a bullectomy by this same DR.

Thank you in advance.
Frank

It is, of course, impossible for me to offer specific diagnostic advice to patients over the internet. In general, however, modern CT scanners are usually able to compensate for respiratory movement if patients more-or-less hold their breath during the scan. If you rapidly inhaled or exhaled during the scan, however, then some movement artifact might occur. You will have to repeat a CT scan of your chest in 3 to 6 months to further assess this finding on your recent scan,
