Multiple bilateral sub 4mm lung nodules stable since last ct scan 2007. how come no other chest ct scan mentioned these since 2007? but they mentioned it in my cardiac calcium scan? ive had a few chest cts since 2007 and they never mentioned any it?

Access to previous studies (for comparison) may have not been possible, changes might be transient or evading the scanner’s resolution or radiologist’ s not considering them pertinent, sometimes mentioned as unchanged from previous are possible explanations. The type of symptoms you experience and/or the reason for having so many studies may further explain changes in reporting.
