    Area of Science:

    • Radiology
    • Endocrinology
    • Medical Imaging

    Background:

    • Computed tomography (CT) is crucial for thyroid imaging.
    • Establishing normal reference ranges for thyroid CT parameters is essential for accurate diagnosis.
    • Various thyroid pathologies require detailed imaging characterization.

    Purpose of the Study:

    • To establish normal computed tomography (CT) density and volume ranges for the thyroid gland in different age groups.
    • To characterize the CT features of common thyroid abnormalities.
    • To provide a basis for differentiating normal from abnormal thyroid tissue on CT scans.

    Main Methods:

    • Unenhanced CT scans were performed on 50 healthy volunteers to establish normal ranges.
    • Pre- and postcontrast CT scans were performed on 47 patients with various thyroid pathologies.

  • CT densities and volumes were measured and analyzed for normal and abnormal thyroid tissues.

    • Main Results:

    • Normal ranges for thyroid CT density and volume were established for various age groups.
    • Distinct CT characteristics were observed for hemorrhagic cysts, multinodular goiter, thyroiditis, papillary carcinoma, and benign adenomas.
    • Differences in CT features were noted between abnormal and uninvolved portions of the thyroid gland.

    Conclusions:

    • CT provides valuable information for assessing thyroid gland volume and density.
    • Specific CT findings can help differentiate various thyroid pathologies.
    • Further studies are warranted to refine the diagnostic utility of CT in thyroid imaging.
