  2. Computed tomography of the thyroid - Wikipedia

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

    Thyroid disorders are common and include many entities. They can be symptomatic, asymptomatic, diffuse, focal, neoplastic, or non-neoplastic processes.Neck ultrasound (US), with the prospect of proceeding to fine needle aspiration (FNA), is the first line of investigation; however, other options are available.

  3. Thyroid nodule - Wikipedia

    en.wikipedia.org/wiki/Thyroid_nodule

    TSH – A thyroid-stimulating hormone level should be obtained first. If it is suppressed, then the nodule is likely a hyperfunctioning (or "hot") nodule. These are rarely malignant. FNAC – fine needle aspiration cytology is the investigation of choice given a non-suppressed TSH. [27] [28] ImagingUltrasound and radioiodine scanning.

  4. Anaplastic thyroid cancer - Wikipedia

    en.wikipedia.org/wiki/Anaplastic_thyroid_cancer

    Anaplastic thyroid cancer seen on an ultrasound image Anaplastic thyroid carcinoma cells. ATC is considered an emergency cancer diagnosis since it poses a high risk of blocking the airway and/or esophagus due to its rapid growth in the neck, either of which can quickly cause a person's death by asphyxiation, if not immediately corrected.

  5. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.

  6. Papillary thyroid cancer - Wikipedia

    en.wikipedia.org/wiki/Papillary_thyroid_cancer

    Other investigation methods include ultrasound imaging and nuclear scan. The ultrasound is a useful test to distinguish solid from cystic lesions and to identify calcifications. [4] The thyroid ultrasound is also very effective to discover microcarcinomas, which refer to very small carcinomas (<1 cm).

  7. 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]

  8. Thyroglossal cyst - Wikipedia

    en.wikipedia.org/wiki/Thyroglossal_cyst

    Ultrasound image of thyroglossal duct cyst. Diagnosis of a thyroglossal duct cyst requires a medical professional, and is usually done by a physical examination. It is important to identify whether or not the thyroglossal cyst contains any thyroid tissue, as it can define the degree of cyst that is being dealt with. [1]

  9. Thyroid - Wikipedia

    en.wikipedia.org/wiki/Thyroid

    The thyroid gland surrounds the cricoid and tracheal cartilages and consists of two lobes. This image shows a variant thyroid with a pyramidal lobe emerging from the middle of the thyroid. The thyroid gland is a butterfly-shaped organ composed of two lobes, left and right, connected by a narrow tissue band, called an "isthmus". [4]
