Did the radiologists report include a Lung-RADS category?
I asked about Lung-RADS category because I get low-dose CT imaging done once a year for screening, and those categories are used in the radiologists reports from those. Length of time for a follow up scan is based on them, either 3 months, 6 months, or a year. What your doctors recommend with respect to following up is no doubt appropriate, mine has routinely been annual except for one year where it was done in 3 months. The waiting was the hardest part!
