  2. Thyroid nodule - Wikipedia

    en.wikipedia.org/wiki/Thyroid_nodule

    An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [32]

  3. Computed tomography of the thyroid - Wikipedia

    en.wikipedia.org/wiki/Computed_tomography_of_the...

    An incidentally discovered colloid nodule with calcification, shown on CT scan of a 58-year-old female patient. a Non-enhanced axial CT scan of the neck demonstrates a coarse calcification at the left thyroid inferior pole. b Sagittal grey scale ultrasound of the thyroid demonstrates a heterogeneous nodule with a predominant cystic component.

  4. Colloid nodule - Wikipedia

    en.wikipedia.org/wiki/Colloid_nodule

    Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]

  5. Thyroid disease - Wikipedia

    en.wikipedia.org/wiki/Thyroid_disease

    The ultrasound may also locate nodules that are too small for a doctor to feel on a physical exam, and can demonstrate whether a nodule is primarily solid, liquid , or a mixture of both. It is an imaging process that can often be done in a doctor's office, is painless, and does not expose the individual to any radiation.

  6. Elastography - Wikipedia

    en.wikipedia.org/wiki/Elastography

    An ARFI image of a thyroid nodule in the right thyroid lobe. The shear wave speed inside the box is 6.24 m/s, which is reflective of a high stiffness. Histology revealed papillary carcinoma. Acoustic radiation force impulse imaging (ARFI) [5] uses ultrasound to create a qualitative 2-D

  7. Radioactive iodine uptake test - Wikipedia

    en.wikipedia.org/wiki/Radioactive_iodine_uptake_test

    The patient swallows a radioisotope of iodine in the form of capsule or fluid, and the absorption (uptake) of this radiotracer by the thyroid is studied after 4–6 hours and after 24 hours with the aid of a scintillation counter. The dose is typically 0.15–0.37 MBq (4–10 μCi) of 131 I iodide, or 3.7–7.4 MBq (100–200 μCi) of 123 I ...

  8. Cold nodule - Wikipedia

    en.wikipedia.org/wiki/Cold_nodule

    A cold nodule is a thyroid nodule that does not produce thyroid hormone. [1] On a radioactive iodine uptake test a cold nodule takes up less radioactive material than the surrounding thyroid tissue. [1] A cold nodule may be malignant or benign. [1] On scintigraphy cold nodules do not show but are easily shown on ultrasound. [2]

  9. Hashimoto's thyroiditis - Wikipedia

    en.wikipedia.org/wiki/Hashimoto's_thyroiditis

    Key features detected in the ultrasound of a person with Hashimoto's thyroiditis include "echogenicity, heterogeneity, hypervascularity, and presence of small cysts." [15] Images obtained with ultrasound can evaluate the size of the thyroid, reveal the presence of nodules, or provide clues to the diagnosis of other thyroid conditions. [52]
