show the size and number of nodules
on your thyroid.
Can an ultrasound detect thyroid cancer?
High resolution ultrasound can detect
a diagnosis of papillary thyroid cancer spread to lymph nodes as small as 1-2 mm (the size of a tip of a ball point pen). When looking at the lymph nodes in the neck with ultrasound, the following are important criteria which may lead to a FNA needle biopsy to confirm disease.
What can show up on a thyroid ultrasound?
A thyroid ultrasound is usually done when physical exam shows any of these findings: You
have a growth on your thyroid gland
, called a thyroid nodule. The thyroid feels big or irregular, called a goiter. You have abnormal lymph nodes near your thyroid.
Can an ultrasound determine if a thyroid nodule is benign?
The vast majority — more than 95% — of thyroid nodules are benign (noncancerous). If concern arises about the possibility of cancer, the doctor may simply recommend monitoring the nodule over time to see if it grows.
Ultrasound can help evaluate a thyroid nodule
and determine the need for biopsy.
What does red mean on a thyroid ultrasound?
By definition,
flow towards the transducer is depicted in
red while flow away from the transducer is shown in blue. Different shades of red and blue are used to display velocity. Lighter shades of color are assigned to higher velocities.
What size thyroid nodule is worrisome?
Nodular size of
1 – 1.9 cm
was more prevalent among cancer patients than in benign cases (p<0.001). The highest malignancy risk was observed in nodules <2 cm and no increase in malignancy risk for nodules >2 cm.
How does thyroid cancer make you feel?
Most often, thyroid cancer causes
a lump and/or swelling of the neck
, but it may also cause difficulty breathing or swallowing, as well as vocal hoarseness. Other symptoms include neck pain that may radiate up to your ears or a persistent cough not caused by illness.

lymph nodes in the neck
and only 1-4% having spread of the cancer outside of the neck to other organs such as the lungs and bone.
Can a thyroid ultrasound detect Hashimoto’s?
Hashimoto’s thyroiditis is supported by a blood test for Thyroid Peroxidase Antibodies (TPO) or Thyroglobulin Antibody. Ultrasound is used to see the thyroid gland and the lymph nodes of the neck. In Hashimoto’s thyroiditis, diffuse vascularity
can be seen
.
Why would a doctor order a neck ultrasound?
Your doctor would order an ultrasound of the neck if he or
she suspects a problem or a developing condition in your carotid arteries, lymph nodes or thyroid
.
What percent of thyroid biopsies are cancerous?
Overall,
about 5–10% of
thyroid FNAs will have malignant cytology, 10–25% will be indeterminate or suspicious for cancer, and 60–70% will be benign (5, 6). Patients with nodules that are malignant or suspicious for cancer by FNA usually undergo thyroid surgery.
What size thyroid nodule should be biopsied?
According to the Society of Radiologists in Ultrasound, biopsy should be performed on a nodule
1 cm in diameter or larger with microcalcifications
, 1.5 cm in diameter or larger that is solid or has coarse calcifications, and 2 cm in diameter or larger that has mixed solid and cystic components, and a nodule that has …
At what size should a thyroid nodule be removed?
Previous studies had shown that between 11- 20% of cancerous nodules ≥ 4 cm may be misclassified as benign (false negative) and this has led to recommendations that all
nodules > 4 cm should
be removed.
What happens if you have a cancerous thyroid nodule?
Thyroid Cancers. Five to 10 percent of thyroid nodules are malignant, or cancerous, although
most cause no symptoms
. Rarely, they may cause neck swelling, pain, swallowing problems, shortness of breath, or changes in the sound of your voice as they grow.
