Thyroid nodule examination Learn all about the methods used to test for thyroid nodules
Thyroid nodules are a common thyroid disease, and in order to confirm the diagnosis, doctors usually perform a series of tests. The following are common tests for thyroid nodules:
1.Thyroid ultrasound.
Thyroid ultrasound is a non-invasive, radiation-free examination method that shows the morphology and structure of the thyroid gland through high-frequency sound waves, and is the preferred examination method for thyroid nodules. Ultrasonography can reveal the size, shape, location, number and adjacency of the nodule to the surrounding tissues, and can also preliminarily determine the benign and malignant nature of the nodule.
2.Thyroid function tests.
Thyroid function tests include the measurement of thyroid hormone and thyroid-stimulating hormone to determine the functional status of the thyroid gland. In people with thyroid nodules, thyroid function tests can help determine whether the nodules are affecting thyroid function.
3.Fine-needle aspiration biopsy.
Fine-needle aspiration biopsy is a method in which thyroid nodule tissue is removed by a fine needle for pathological examination. This method can help determine the benign and malignant nodules and is an important means for the diagnosis of thyroid cancer.
4.MRI.
Magnetic resonance imaging is an imaging test that provides detailed morphological and structural information about thyroid nodules. For some specific types of thyroid cancer, MRI can help detect microscopic lesions and metastases.
5.Doctor palpates.
Palpation by a doctor is a method of making a preliminary determination of the size, shape and texture of the nodule by palpating the thyroid gland. This method is simple and easy, but it can be difficult to detect for smaller nodules.
6.Laboratory tests.
Laboratory tests include measurement of complete blood count, erythrocyte sedimentation rate, C-reactive protein, etc., which can provide information on the general condition and inflammatory response of the nodule. For some types of thyroid cancer, laboratory tests can help detect abnormal markers.
7.Antibody testing.
Tests for thyroid-related antibodies can help diagnose autoimmune thyroid disease. Common antibody tests include anti-thyroglobulin antibodies, anti-thyroid peroxidase antibodies, etc. For some types of thyroid nodules, antibody testing can help determine the prognosis.
