Thyroid nodule management is quite complex, with multiple criteria and recommendations coming from different sources, including recommendations for incidental nodules seen on CT. Some of the recommendations are summarized below.
Society of Radiologists in Ultrasound (SRU): The recommendations of the SRU, published in Radiology 2005 here, may appear a little dated now, but are still followed widely.
American Thyroid Association (ATA): The ATA gave more recent recommendations in 2015; these can be (open) accessed here. The ATA guidelines are extensive and on the diagnosis and management of nodules and cancer, and for those of you who want to read details, the guidelines related to ultrasound recommendations are given on Recommendations 7 and 8, Fig 1 and 2, and Tables 6 and 7.

TI-RADS: The ACR TI-RADS is now evolving as well, and can be referred to here.
ACR CT, MRI and PET/CT Incidentaloma Guidelines: The ACR has also made recommendations in 2014 for managing incidental thyroid nodules detected on CT/ MRI/ PETCT. These can be accessed here (paid-access).
