What does mildly heterogeneous thyroid gland mean?
Heterogeneous echogenicity of the thyroid gland is a non-specific finding and is associated with conditions diffusely affecting the thyroid gland. These include: Hashimoto thyroiditis. Graves disease.
Does thyroid cancer show up on CT scan?
CT Scan. Computed tomography, commonly called a CT scan or CAT scan, uses special X-rays to give your doctor a look inside of your body. It can show the size and location of thyroid cancer and whether it has spread to other parts of your body.
What does heterogeneous mean on ultrasound?
Heterogeneous refers to a structure with dissimilar components or elements, appearing irregular or variegated. For example, a dermoid cyst has heterogeneous attenuation on CT. Heterogenous is, therefore, the antonym of homogenous, meaning the tissue or structure is located or originates from an expected location.
What is a heterogeneous hypoechoic nodule in thyroid?
A hypoechoic nodule, sometimes called a hypoechoic lesion, on the thyroid is a mass that appears darker on the ultrasound than the surrounding tissue. This often indicates that a nodule is full of solid, rather than liquid, components.
What size thyroid nodule should be biopsied?
Current guidelines recommend biopsy of many thyroid nodules >5 to 15 mm in diameter. However, the new findings suggest the presence of two of three abnormal characteristics found on ultrasound may further refine the decision for biopsy.
What percentage of suspicious thyroid nodules are cancerous?
Thyroid nodules are a common finding in the United States with 19–67% of the general population having one or more thyroid nodules detectable by ultrasound (1). However, studies show that only 1 in 20 of these nodules is cancerous (2).
How can you tell if a thyroid nodule is malignant?
If your doctor thinks a biopsy is needed, the simplest way to find out if a thyroid lump or nodule is cancerous is with a fine needle aspiration (FNA) of the thyroid nodule. This type of biopsy can sometimes be done in your doctor’s office or clinic.
How often are highly suspicious thyroid nodules cancerous?
Thyroid nodules occur in 4% to 8% of the general population. Nodules detected with ultrasound and at autopsy increase the prevalence to 50% to 70%. The majority of thyroid nodules are benign with malignancy in approximately 4% to 12% in palpable thyroid nodules as well as nonpalpable incidentalomas.
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.
Are all suspicious thyroid nodules cancerous?
A nodule can be benign, or noncancerous; toxic, meaning it produces too much thyroxine; or cancerous. Doctors at NYU Langone are experts in determining what type you have and choosing the appropriate treatment. About 90 to 95 percent of thyroid nodules are benign.
What percentage of TR5 thyroid nodules are cancerous?

Can TR5 nodules be benign?
In TR5 14/46 (30.4%) of the nodules were benign and 32/46 (69.6%) malignant, 11/46 (23.9%) <1 cm in size and 35/46 (76.1%) – ≥1 cm. Size of ≥1 cm had sensitivity of 68.75%, specificity of 7.14%, PPV of 62.68%, NPV of 9.09% and accuracy of 50%.
