A 48-year-old male patient post total thyroidectomy with PTC recurrence. a Transverse greyscale ultrasound of the neck demonstrates a left thyroid bed heterogeneous, predominantly hypoechoic irregular lesion with calcifications (white arrow). b A spot image of iodine 123 total body scan of the neck demonstrate a focus of abnormal radiotracer ...
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.

Image General: Ultrasound system: A console, or a portable system, which includes a monitor and a transducer, and utilizes ultrasound to image body tissues. To image the thyroid and parathyroid glands and neck lymph nodes; also, to guide diagnostic fine needle aspiration [4] or therapeutic ethanol injection to these organs. [5]
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]
Most structures of the neck, including the thyroid and parathyroid glands, [24] lymph nodes, and salivary glands, are well-visualized by high-frequency ultrasound with exceptional anatomic detail. Ultrasound is the preferred imaging modality for thyroid tumors and lesions, and its use is important in the evaluation, preoperative planning, and ...
However, current protocol (in the USA) suggests a small number of clean annual WBS are required before relying on Tg testing plus neck ultrasound. When needed, whole body scans consist of withdrawal from thyroxine medication and/or injection of recombinant human Thyroid stimulating hormone (TSH). In both cases, a low iodine diet regimen must ...
Other clinical signs that could indicate papillary thyroid are fixation to the trachea, a firm neck mass, damage to recurrent laryngeal or cervical sympathetic nerves. Five percent of the population can have thyroid nodules, and the majority will be benign. [6] Appropriate workup includes an ultrasound of the neck, followed by lab studies.
The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans, it is a butterfly-shaped gland located in the neck below the Adam's apple. It consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the isthmus (pl.: isthmi).
