How Do I Get A Thyroid Ultrasound

This exam is covered under your Alberta Health Care Insurance Plan and must be requested by a health care practitioner. To determine whether its appropriate for you, your doctor will often review your medical and family history, risk factors, how long symptoms have been present, and how they affect daily activities. If a thyroid ultrasound is indicated as a best next course of action, your doctor will provide you with a requisition and the appointment can be booked.

Mayfair has 12 locations which offer thyroid ultrasounds, and thyroid biopsies are performed at our location.

Thyroid Nodules And Treatment: Get The Facts

    For many patients, being told they have athyroid nodule instantly raises red flags. DoI have cancer? Will I need surgery? Should I be worried?

    The answer to these questions is usually, butnot always, no. Thyroid nodules are lumps that form within your thyroid, abutterfly shaped gland located at the base of your neck. Nodules can be solidor contain a variable amount of fluid. If they are completely fluid-filled,they are called thyroid cysts.

    Thyroid nodules are more common in womencompared to men and more likely to occur as you get older. The exact reason whysome people get thyroid nodules and others dont is not known, but nodules tendto run in families.

    Most thyroid nodules are benign and cause no problems if left untreated. However, approximately 5 to 10 percent of thyroid nodules are cancerous but even then, a patient might not need surgery right away because most thyroid cancers grow slowly.

    If you have been diagnosed with a thyroid nodule, the first step is to see an endocrinologist a doctor who specializes in conditions of the endocrine glands, such as the thyroid.

    Most thyroid nodules are benign and cause no problems if left untreated. However, approximately 5 to 10 percent of thyroid nodules are cancerous but even then, a patient might not need surgery right away because most thyroid cancers grow slowly.

    Management Of Thyroid Nodules

    In addition to the clarification of terminology in cytopathologic reporting, the Bethesda conference also established a consensus for the indications to perform FNAB of thyroid nodules, as well as post-FNAB management options. The current state of the art in thyroid FNAB is nicely outlined in a review by Layfield et al.

    The most important routine aspects of the diagnostic evaluation of solitary thyroid nodules include thorough history-taking and physical examination, measurement of the serum TSH level, ultrasound-imaging, and FNAB of the nodule. Subsequent management of a solitary thyroid nodule largely depends on the diagnosis from FNAB.

    Using the Bethesda system, the follicular neoplasm, suspicious for malignancy, and malignant classifications each warrant surgical consultation. Patients with follicular cytopathology on FNAB should be referred to a surgeon because 20-30% of such nodules are malignant. Exceptions may be made in the case of malignant lymphoma, which is typically not managed surgically, and in cases of anaplastic carcinoma, in which surgical intervention may be futile.

    For the atypia of undetermined significance category, management options include the following:

    When findings from the aspirate are nondiagnostic, repeat the aspiration, possibly with ultrasonographic guidance. Nodules for which aspirates are repeated nondiagnostic may ultimately require surgical management.

    Workup And Surgical Recommendations

    Thyroid nodules  time for a rational imaging approach ...

    We have proposed the algorithm in for the thyroid surgeonâs workup of a thyroid nodule. It is based upon the 2006 ATA guidelines for the workup of a thyroid nodule with incorporation of mutational analysis . One indication for surgery is whether the nodule is symptomatic due to compression of nearby structures. These patients are typically evaluated with CT or MRI and loop spirometry, and a lobectomy is typically performed to remove the compressive lesion. In rare instances, a total thyroidectomy is indicated if both lobes of the thyroid are problematic. Any asymptomatic thyroid nodule should be evaluated with a diagnostic ultrasound and a TSH level. Often times, these tests have been completed prior to a patientâs arrival in the surgeonâs office. Nodules smaller than 1 cm in diameter should be followed with a yearly ultrasound, with FNAB indicated for any concerning changes in appearance or growth. A biopsy of subcentimeter nodules may be indicated if there is a significant history of radiation exposure, a strong family history of thyroid carcinoma, or worrisome sonographic features.

    Indeterminant Thyroid Nodule Biopsy: What Happens If The Biopsy Has A Result Of Undetermined Significance

    ACUS is an abbreviation for âatypical cells of undetermined significanceâ. This occurs when the thyroid FNA findings donât show for sure if the nodule is either benign or malignant. The pathologist looks at the cells and just can’t be sure if it is cancer, or non-cancer . If this happens, an option that your doctor has is to gentic testing done on the cells of the biopsy to see if there are genetic abnormalities seen. There are several commercially available tests that doctors can send the samples to determine the risk of the cells being cancerous–they look for several specific abnormal pieces of DNA that are frequently associated with thyroid cancer. Before you consider one of these genetic tests, you should ask yourself âwhat information do I seek?â and âHow will this information change my approach to my thyroid mass?â The point being, many thyroid nodule biopsies do not need this expensive genetic testing , and if the answer isn’t going to change what you are going to do, then don’t spend the extra money getting genetic testing. For example, if the thyroid nodule has other characteristics or symptoms and the plan is to have surgery to remove the nodule, then don’t bother with the genetic testing. It won’t change what you are planning on doing–you are already planning surgery.

    Should A Benign Kidney Tumor Be Removed

    Because benign kidney tumors do not require removal, a kidney specialist known as a urologist may order additional tests to help determine if a tumor is benign before treatment decisions are made. These tests may include imaging tests or a biopsy, in which a sample of the tumor is taken with a needle.

    What Determines If A Thyroid Nodule Is Cancerous

    The only way to definitively determine if a thyroid nodule is cancerous is to examine it under a microscope. The most common method is called fine need aspiration biopsy, where a very small needle is inserted into the thyroid nodule and cells are removed for microscopic examination. However, only a small percentage of nodules are cancerous, and, of those, an even smaller percentage requires treatment. Most thyroid cancers are curable and rarely cause life-threatening problems.

    At Mayfair Diagnostics, we follow the American College of Radiologys Thyroid Imaging, Reporting, and Data System for the classification and evaluation of thyroid nodules. Our thyroid ultrasound reports to your doctor describe the nodules features, assess the risk of malignancy, and help determine next steps, such as the need for FNA or ultrasound follow-up to monitor nodule growth or development of worrisome features.

    The goal of TI-RADS is to help you and your doctor balance the benefit of identifying cancers that require treatment against the risk of biopsy and treatment of benign nodules or indolent cancers cancers that are slow-growing and will almost certainly never be problematic.

    Thyroid Cancer Affects Thousands Of People

    Thyroid Nodule

    Although thyroid cancer has a low death rate compared to most other cancers, it still has far-reaching effects.

    An estimated 62,450 people in the United States will develop thyroid cancer and 1,950 people will die from it this year, according to the American Cancer Society .

    The key to successful recovery from thyroid cancer lies in early detection.

    The ACS reports that nearly 100 percent of people with stage 1 or 2 thyroid cancer survive at least five years, a number that drops to around 50 percent by stage 4. By screening for thyroid nodules, doctors can catch cancer at its earliest stages.

    An annual physical examination of the thyroid is recommended in asymptomatic individuals as well as examination in anyone with symptoms that could suggest thyroid disease, said Alexander. Most nodules are asymptomatic, hence the routine examination of the neck and thyroid structures is very important for detection of nodules and potential thyroid cancer.

    Currently, the ATA recommends that people with benign thyroid nodules get checked every six to 18 months. If the nodules do not grow in size, this interval can be extended to three to five years.

    Who Needs A Fna Needle Biopsy Of Their Thyroid Nodule

    FNA biopsy should be done on any nodule that the doctor thinks may be cancerous

    • FNA needle biopsy of thyroid nodules is generally done on any thyroid nodules that is big enough to be felt. This means that they are larger than about 1 centimeter across.
    • FNA biopsy is indicated on any thyroid nodule that causes symptoms. We have an entire page on symptoms caused by thyroid nodules.
    • FNA biopsies should be done on any swollen or abnormal lymph nodes in the neck. This may be more accurate in diagnosing thyroid cancer than FNA of the thyroid nodule itself!
    • FNA biopsy should be done on thyroid nodules that have a certain characteristic under the ultrasound.

    I Have Thyroid Nodules Should I Be Worried

    A thyroid nodule is a growth within the thyroid a butterfly shaped gland located just below the Adams apple in the neck. The thyroid sends out hormones that help control the bodys metabolism. Thyroid nodules are very common and occur in 30% of all people in the United States. Like most thyroid conditions, nodules are more common among women than men. They are also more common with older age. By the age of 60, more than half of women will have a thyroid nodule. Sometimes nodules go undetected, other times you or a health care provider may feel them in the neck, or they may be seen on ultrasound or CT scan that you have for another reason.

    If you learn that you have a thyroid nodule the first thing to do is see your primary care provider to obtain more information. Does your thyroid function normally or is it overactive a condition called hyperthyroidism? Symptoms of hyperthyroidism include nervousness, feeling hot, weight loss or tremor. Does the thyroid not produce enough hormone? This condition, called hypothyroidism, has the opposite symptoms including fatigue, sleepiness, weight gain, and thinning hair. Your doctor can determine if you have either of these with a simple blood test called thyroid stimulating hormone, or TSH. Your doctor will also obtain an ultrasound of your neck to see more detail of your thyroid if you have not had this already.

    Causes Of Thyroid Nodules

    Thyroid nodules, masses in the thyroid gland, can be the result of benign cell overgrowth or actual discrete tumors comprised of thyroid cells that can be benign or cancerous. Thyroid nodules can sometimes contain fluid, which usually collects due to bleeding from the fragile blood vessels in thyroid tumors, so called cystic degeneration. This event sometimes causes the sudden onset of pain and swelling in the front of the neck, which typically subsides over several days.

    Fortunately, more than 90% of thyroid nodules are not cancers, but malignancy should be considered in every affected person. Often patients with small thyroid nodules, less than 1 cm in diameter, and no risk factors for thyroid cancer can simply be reexamined or imaged by sonography to be sure the nodule is not enlarging. For larger nodules, additional studies are usually indicated, as described below.

    Thyroid Nodules Are Usually Benign And Not Cancerous

    Thyroid nodules  time for a rational imaging approach ...

    The good news is that most people with thyroid nodules do not and will not get thyroid cancer.

    The bad news is that a thyroid nodule is not normal and may be associated with other conditions of your thyroid gland.

    So, even if you don’t have thyroid cancer, you should still have your thyroid nodule evaluated and tested for other conditions which are associated with thyroid nodules.

    Conditions in this category include:

    It’s important to realize that many thyroid nodules are just run-of-the-mill nodules which are not associated with thyroid disease of any kind.

    But, in order to be on the safe side, it’s ideal that every patient who has a thyroid nodule undergoes certain tests to ensure that this is the case.

    Tests such as a comprehensive history and physical, palpation of the thyroid gland, tests of your thyroid function through blood work, and even an ultrasound may all be warranted.

    Your doctor should be walking you through these steps but you can also ask for them if you are worried.

    Thyroid Nodule Treatment Options

    Most nodules, benign or cancerous, are not an immediate health risk. However, as with most conditions, treating the issue early is less intensive and less invasive than waiting until it becomes serious.

    The treatment your endocrinologist recommends will depend upon the nodule characteristics:

    If you are diagnosed with a thyroid nodule, dont panic. The majority of thyroid nodules are benign, and most do not require surgery. See an endocrinologist to find the most effective treatment option for you and to get your questions answered.

    Thyroid Nodule: When Is A Radioiodine Scan Ordered

    Only in instances where the blood test to examine the thyroid nodule patient demonstrates that hyperthyroidism is present in addition to the presence of the thyroid nodule, is a radioiodine scan indicated. In these cases, the thyroid stimulating hormone will be very low. The thyroid nodule patient may or may not have recognized symptoms of hyperthyroidism. If the TSH level is normal, there is absolutely no contemporary indication for a thyroid scan.

    During the thyroid scan, the patient will be given a small amount of radioactive iodine in their vein and a special imaging camera is utilized to determine how much iodine is taken up by the thyroid gland and if the nodule takes up iodine relative to the remainder of the thyroid gland . If the nodule has less iodine uptake than the rest of the thyroid gland, then the thyroid nodule is called a âcold noduleâ.

    Hot nodules are almost always non-cancerous but the preferred management of hot nodules is frequently surgery since it is a clear, safe and 100% effective therapy for the hyperthyroidism. Cold nodules have a higher incidence of malignancy than hot nodules but still most are benign.

    Youve Been Diagnosed With A Large Thyroid Noduleshould You Be Concerned

    The findings from this meta-analysis should prompt you to have a frank discussion with your physician, Dr. Cipriani tells EndocrineWeb.

    Many other factors come into play in deciding whether to choose to have surgery to remove a nodule, she says. Certainly If after hearing all the pros and cons of having surgery, and still feeling too unsettled with the idea of active surveillance , then this discomfort must be addressed in the discussion about treatment options and options for next steps, for instance.

    On the other hand, for patients who are older and at greater risk of complications from surgery for a thyroid nodule that poses no issues and isnt bothering them, that too should be considered, she says.

    What was not known from the studies that Dr. Cipriani’s team evaluated is the interval between the biopsy and the surgery? When surgery is done, she says, the usual procedure is to remove at least one of the two thyroid lobes. To surgically remove just a nodule is more complicated, she says, but this means that the patient may not need thyroid replacement hormone, which, if necessary, must be taken for the remainder of the patients life.
