This is definitely a part of standard follow up for small findings and part of the guidance for incidentally detected lung nodules smaller than <8mm.

I think mammography is a great example. Many people are quite surprised to hear that the Positive Predictive Value of a screening mammography is only in 10-15% range. This despite mammography being a pretty sensitive test. This is because despite good test performance characteristics, applied across a large population of relatively health people, the 2-5% false positive rate is a large number of people.
