Herts}, journal={Radiology}, year={2012}, volume={262 1 There is uncertainty with regard to the duration of follow up imaging for these lesions. Bosniak has suggested that for lesions with less worrisome features (meaning they are closer in resemblance to type 2 than type 3), 1-2 years of follow up with CT is sufficient [2].
