What thyroid cancer looks like on ultrasound?

Ultrasound is an ideal imaging modality for the detection and evaluation of a thyroid nodule. It is easy to perform, widely available and does not involve ionization. Summary · Introduction · Using Ultrasound on the Thyroid. Ultrasound uses sound waves to create images of parts of the body.

You are not exposed to radiation during this test. Medullary thyroid cancer (TCM) has a more aggressive behavior and a poor prognosis. Ultrasound (US) has facilitated the qualitative diagnosis of thyroid nodules, however, some TCM may be diagnosed as a benign nodule on ultrasound due to the lack of ultrasound characteristics of the malignancy. The objective of the study was to investigate the association between ultrasound characteristics and biological behavior of TCM.

ULTRASOUND (US) is useful for the evaluation of thyroid nodules due to its safety, non-invasiveness, non-radioactivity and efficacy. Currently, real-time high-resolution US not only detects the presence, site, number and size of thyroid nodules, but also clearly shows the characteristics of thyroid nodules. However, the differentiation between malignant and benign nodules in the United States is not well described.1-12 Some authors have reported American diagnoses of thyroid nodules of all types with relatively high sensitivity ranging from 74% to 81% ,3,6,7,9 but formulas based on analysis of thyroid nodules are not available EE features. predict malignancy.

Any useful formula must be simple and accurate for clinical use. Therefore, we evaluated the American characteristics of thyroid nodules prospectively and analyzed the likelihood of malignancy based on a multiple logistic regression analysis. The most common type of thyroid cancer, papillary cancer, which accounts for approximately 85% of cases, cannot be diagnosed with laboratories. A common way to treat thyroid cancer is to remove most of the thyroid by surgery and then use radioactive iodine to destroy any remaining thyroid cells.

For a thyroid scan, the camera is placed in front of the neck to measure the amount of radiation in the gland. The risk of cancer is also low in patients in whom the only characteristic of ultrasound is a simple cyst (0.32 cancers per 1000 patients). Significance There is wide variation in the management of thyroid nodules identified in ultrasound imaging. As noted above, ultrasound is also used to guide and perform a needle biopsy of a nodule to diagnose thyroid cancer.

A disadvantage of this is that it can cause symptoms of hypothyroidism, such as tiredness, depression, weight gain, drowsiness, constipation, muscle aches and decreased concentration. Self-examination and regular, routine follow-up with your family doctor are also important for diagnosing thyroid cancer. You may have heard of another marker of thyroid cancer, thyroglobulin, that can be evaluated or followed after treatment for thyroid cancer. The risk of cancer based on the appearance of the thyroid in the ultrasound image is shown in Table 6.

Doctors often use ultrasound to look at the thyroid during the biopsy, which helps make sure they are taking samples from the correct areas. Thyroid nodules were common in patients diagnosed with cancer (96.9%) and in patients who were not diagnosed with thyroid cancer (56.4%). Radioactive iodine scans work best if patients have high levels of thyroid-stimulating hormone (TSH or thyrotropin) in their blood. Therefore, routine measurement of serum calcitonin should be recommended in the initial evaluation of thyroid nodules.
