When it comes to checking your thyroid health, you might be wondering whether to choose “ultrasound” or “CT scan.” Both methods have their unique strengths and limitations. Let’s understand them to make the best decision for your health.

    • Affordable
  • Limitations
    • Cannot see structures deep within the body or obscured by bone
    • Cannot definitively determine the type of nodule

Thyroid CT Scan

  • How it works Uses X-rays to create cross-sectional images of the thyroid.
  • Pros

    • Helps detect the spread of cancer to lymph nodes or other organs
  • Limitations
