Overview

CT scan has low sensitivity in diagnosing thyroid nodules but it may serve as an alternative imaging modality for the diagnosis of thyroid nodule, in case of large, rapidly growing, retrosternal and invasive tumors.

CT Scan

CT scan is not a good choice for cervical lymph node metastases evaluation because its sensitivity is low (30-40%), but as an alternative imaging modalitiy, it may be useful in the assessment of tumors with the following features:

Thyroid nodule rupture:

Sonography and/or computed tomography (CT) could help diagnose this complication, which is visualized as the breakdown of the thyroid capsule and the formation of a new mass located between intra- and extra-thyroidal lesions at the RF site
