So i had a chest x-ray done a week ago, they found some nodules, well when i went back to a different emergency room they did a ct scan of my chest and lungs and found no nodules, is this possible? to just get rid of them over a week period?

Most likely the CT is more accurate. If you are a smoker, please enroll in a smoking cessation program. Multiple areas of modularity often represent infection or resolving infection. Consult with your physician regarding risk factors such as a family history of lung disease. Watch for signs of fever,cough and sputum production.

yes - there are several causes for an apparent nodule on a chest x-ray. CT is the definitive test, so you can rest assured you are fine.
