Frequently, : Frequently, an abnormality is found which is most likely inconsequential, however rarely may be a problem. An example would be a mass on the adrenal gland. These are commonly seen and are usually benign; meaning they have no consequence. However, rarely they may be cancer. Sometimes, we'll ask for a repeat exam with a different technique for further evaluation to prove they're benign. Other times we would like to see if there has been an interval change; such as with a lung nodule. Lung nodules are frequently seen and are often benign, but we can't know for sure unless we can say it has been stable for a given period of time. There are many other reasons for a repeat exam. I suggest you discuss this with your physician.

Short interval: Followup can be recommended for many findings that are probably benign, but should be evaluated again - sometimes with different technique, other times just to see if they have resolved or to look for interval growth. Please ask your doctor for the specific finding that is leading to the requested short interval followup and consider asking another question here at healthtap if you have questions.
