    Science (New York, N.Y.)·2021

    Area of Science:

    • Nuclear medicine
    • Medical imaging
    • Endocrinology

    Background:

    • Positron emission tomography (PET) is crucial for functional imaging.
    • Accurate thyroid volume assessment is vital for managing thyroid disorders.

    Observation:

    • A high-resolution positron camera was used to image 64 patients with thyroid disorders.
    • Patients received 100-300 mu Ci of iodine-124 (124I), a positron-emitting radioisotope with a 4.2-day half-life.
    • A single 10-15 minute scan produced a 3D image of radioiodine uptake.

    Findings:

    • The 3D imaging technique generated detailed views of radioiodine distribution, including transverse, sagittal, and frontal sections.
    • Thyroid functional volume estimation using voxels showed precision varying from 6-15%.

  • The volume estimation method was validated using phantoms and post-thyroidectomy patient data.

    • Implications:

    • This 3D imaging approach offers a non-invasive method for precise thyroid volume measurement.
    • The technique holds potential for improved diagnosis and personalized management of various thyroid diseases.
    • Enhanced visualization of radioiodine uptake can guide therapeutic decisions in nuclear medicine.
