Ct scan of pelvic abdomen showed 7mm lung spot on lower left lung dr now ordered a chest CT scan wondering why ?

To see the rest of: ...Your lungs. The abdominal study only shows about a third of your lungs. Your doc will need to see the rest to know what to do. Lung nodules are very common and the vast majority are benign scar(s). Most of the time we just use the ct to follow and make sure there is no growth. There are other tests (pet scan for example) that can be useful when there is concern for cancer. ...Read more

What are the risk of chest CT scan?

What are the risk of  chest CT scan?

Risks include....: Radiation imparted to the body as a part of the scan. 1 ct scan of the chest is the equivalent of about 5, 000 chest x-rays.

When you have a chest CT scan is it typical to do a set up lower dose scan before the actual scan? Or was I scanned twice? Scared about rad dose :\

There are inherited traits that lead to increased cancer risk with radiation exposure but even then it would be a very rare occurrence. Cannot say it is impossible, though. That is why scans have to be ordered when truly necessary, not capriciously. ...Read more
