Ultrasound Imaging of Thyroid Gland procedure provides detailed images of thyroid gland and surrounding structures, to help diagnose thyroid nodules and other abnormalities. This is an Ultrasound of the Thyroid Gland showing a large cyst of the thyroid.


Background Information:

What are the other Names for the Procedure?

  • Thyroid Sonography Procedure
  • Thyroid Ultrasound Imaging Procedure
  • Thyroid USG Procedure

What is Ultrasound Imaging Scan of the Thyroid radiology procedure? (General Explanation)

  • Ultrasound imaging is a noninvasive procedure that uses high frequency sound waves to produce real-time images. The procedure can be used to show movement of internal organs and blood flowing through blood vessels
  • Ultrasound Imaging of Thyroid Gland procedure provides detailed images of thyroid gland and surrounding structures, to help diagnose thyroid nodules and other abnormalities

What part of the Body does the Procedure involve?

An Ultrasound Imaging of Thyroid Gland involves the neck region of the patient.

Why is the Ultrasound Imaging Scan of the Thyroid radiology procedure Performed?

Ultrasound Imaging of Thyroid is performed to diagnose various medical conditions, such as:

  • To determine size of the thyroid glands
  • To evaluate neck mass that may have originated from thyroid gland, or other structures in the neck
  • To check appearance of the thyroid gland - to see if any nodules have benign or malignant characteristics
  • If the nodule has characteristics of malignancy, a needle biopsy is performed to remove a small sample of the thyroid gland

What is the Equipment used? (Description of Equipment)

The equipment for ultrasound imaging consists of:

  • An ultrasound transducer
  • A computer monitor
  • A central processing unit
  • A printer

A transducer is used to send high frequency sound waves in the body and the computer creates the image based on the echoes of that sound returning from the patient’s body.

What are the Recent Advances in the Procedure?

There have been no recent advances in the field of Thyroid Ultrasound Imaging Procedure.

What is the Cost of performing the Ultrasound Imaging Scan of the Thyroid radiology procedure?

The cost of a Thyroid Ultrasound Imaging Procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.

In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary. 

When do you need a Second Opinion, prior to the Procedure?

  • It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding the Thyroid Ultrasound Imaging Procedure and what needs to be done
  • If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician
  • Also, if the procedure involves multiple steps or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently

Prior to Ultrasound Imaging Scan of the Thyroid radiology procedure:

How does the Ultrasound Imaging Scan of the Thyroid radiology procedure work?

Ultrasound Imaging of Thyroid procedure works in the following manner:

  • The ultrasound procedure works on similar principles used in sonar by submarines, to determine the size and shape of the object and how far away the object is
  • The transducer sends out high frequency sound waves in the body. When sound waves echo back from the body, the microphone in the transducer records the changes in the sound
  • And using the changes in the sound, it is possible to determine the shape, size, or any other changes in the structure of the organ
  • Using the change in the echoed sound, a computer produces a picture in real-time on the screen
  • Doppler ultrasound is used to determine the direction and speed of the blood cells

How is the Ultrasound Imaging Scan of the Thyroid radiology procedure Performed?

An Ultrasound of Thyroid Imaging Procedure is performed in the following manner:

  • The patient lies face-up on the table
  • A water-based gel is applied on the area of interest so that transducer can have better contact with the area and air pockets are eliminated between the transducer and body
  • A sonographer puts the transducer on the body and moves it around the area of interest to capture the desired image

Where is the Procedure Performed?

An Ultrasound of Thyroid is performed either as an outpatient or inpatient procedure, at a hospital.

Who Performs the Procedure?

An ultrasound technician performs the Thyroid USG Procedure, under the supervision of a radiologist.

How long will the Procedure take?

A Thyroid Ultrasound Imaging Procedure will take about 30 minutes.

Who interprets the Result?

A radiologist interprets the results of the Thyroid USG Procedure.

What Preparations are needed, prior to the Procedure?

The following preparations may be needed prior to a Thyroid Ultrasound Imaging Procedure:

  • The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient, including information related to the medications that are being currently taken
  • Do inform the medical professional if you have a history of any medical conditions, such as a heart disease, asthma, diabetes, or kidney disease
  • Do inform the medical professional about any allergies, especially related to barium or iodinated contrast material, which may be used in the procedure
  • The ultrasound is not recommended, if the patient had had barium enema or GI tests in the past 2 days
  • It is advisable to wear comfortable and loose clothes. Avoid wearing any metal objects or jewelry, as it may interfere with the scan
  • It is highly recommended to inform your healthcare professional, if you are pregnant or breastfeeding

What is the Consent Process before the Procedure?

  • A physician will request your consent for Ultrasound Imaging of Thyroid Gland using an Informed Consent Form
  • Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent
  • You must sign the forms only after you are totally satisfied by the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure

What are the Benefits versus Risks, for this Procedure?

Following are the benefits of Thyroid Ultrasound Imaging exam:

  • Ultrasound of Thyroid Gland provides detailed images of thyroid gland and surrounding soft tissues in neck region
  • Ultrasounds  do not involve the use of any ionizing radiation
  • Ultrasound imaging is noninvasive, inexpensive, quick, and simple
  • The procedure captures clear images of soft tissues in real-time
  • The procedure can be used in needle biopsies or needle aspiration. 

Following are the risks of Thyroid Ultrasound Imaging exam:

  • Generally none 

What are the Limitations of Ultrasound Imaging Scan of the Thyroid radiology procedure?

Following are the limitations of Thyroid Ultrasound Imaging exam:

  • Ultrasound of Thyroid Gland only gives information about anatomy and structure of thyroid gland, but it does not provide any information about functioning of thyroid
  • Blood tests are necessary to determine over activity or under activity on thyroid gland in hyperthyroidism and hypothyroidism respectively.
  • Ultrasound can only provide information about characteristics of thyroid nodule as benign or malignant, but fine needle biopsy may be necessary in order to determine and prove malignancy and determine what kind of cancer it is
