Choice of modality

  • Ultrasonography of the thyroid is generally the initial investigation of choice for the thyroid.
  • CT of the thyroid plays an important role in the evaluation of thyroid cancer.[1] When performed for other reasons, it often incidentally detects thyroid abnormalities, thereby practically becoming the initial investigation.
  • MRI of the thyroid can be used in the evaluation of thyroid cancers and goiter, and likewise detects incidental abnormalities.[1]
