What are Thyroid Gland CT scans?

The process of taking a CT of the thyroid begins by taking many different X-ray views at various different angles, which are then combined with the use of computer processing to create cross-sectional images of the bones and soft tissue inside of your body.

Ordinary X-ray testing does not show clear images of soft tissue, so doctors often request CT thyroid scanning to get a good image of soft tissue including organs, muscles, blood vessels and nerves. Sometimes a contrast dye is used as it shows up clearer on the screen.

During a quality CT scan, a doctor will be able to see cross-sections of your thyroid. The thyroid CT scan may also be called a neck CT scan.

Reasons for a Thyroid Gland CT scan:

CT scans are used for a multitude of reasons. They may be done to check for certain cancers in various different ways including to detect abnormal tumors, growths or lumps. They also identify the location of tumors, the stage of cancer, and where to perform a biopsy.

A thyroid CT scan can be used to guide doctors or surgeons during a procedure, such as a biopsy. They are important in planning for certain types of therapy and surgery, as well as in the aftermath to determine whether the patient’s body is responding to treatment.

CT scans can be used to detect cysts or infections in the body. They can also identify the bone structures within the body and can accurately measure the density of bone.

A CT scan is often used to quickly inspect a patient after an accident in order to identify traumatic internal injuries, although this usually isn't an issue with thyroids.

Identifying issues or abnormalities of the thyroid with a CT scan may also assist in other ways, such as various natural treatments for hypothyroidism.

A thyroid CT scan may help diagnose (find):

A CT scan of the thyroid may be completed in order to assist a doctor during tissue removal, fluid removal or as a guide during surgery.

When a CT of the thyroid is taken, the spine, airway, carotid vessels and other vasculature as well as salivary and thyroid glands are also included for doctors to view. In many cases, the jaw bone, mouth and tongue, pharynx and larynx, including the vocal cords, are shown.

Doctors frequently order a thyroid CT to evaluate parotid or submandibular gland lesions or infections, head and neck diseases, various abscesses or masses, even foreign bodies that are lodged in the neck or upper airway. CT scans of the neck many times also reveal tumors or infections involving the vocal cords.

Thyroid CT exams are often used to study a lump or mass or to look for enlarged lymph nodes or glands in the neck.
