The effect of B-ultrasound diagnosis of thyroid cancer

Thyroid cancer is a very common type of cancer currently. When examining many patients, doctors use B-ultrasound as the main basis for diagnosis. Therefore, some patients have doubts about this diagnostic method. Can thyroid cancer really be diagnosed through B-ultrasound alone? Today we will learn about the diagnostic effect of B-ultrasound for thyroid cancer.

Let's first look at the other diagnostic methods:

Thyroid cancer lacks specific symptoms, and its clinical manifestations are difficult to differentiate from benign diseases such as nodular goiter and thyroid adenoma, so the correct preoperative diagnosis rate is not high. Although fine needle aspiration can significantly improve the preoperative detection rate, it is invasive and difficult for some patients to accept, and its positive rate is closely related to ultrasound and the experience and technical level of pathologists, so its application is greatly limited and difficult to be widely used in clinical practice.

Let's take a look at the B-ultrasound results:

Color Doppler ultrasound has many advantages such as being economical, non-invasive, and highly repeatable. It has become the preferred method for thyroid cancer examination. In recent years, with the advancement of this technology, the diagnosis rate of thyroid cancer has been greatly improved. The preoperative color Doppler ultrasound diagnosis rate for thyroid cancer can be as high as 88%. Ultrasound characteristics such as low-echo nodules, irregular shapes, unclear boundaries, and calcification are all risk factors for malignancy. However, factors such as whether the nodule is solitary, the size of the nodule, and gender have no obvious correlation with benign or malignant.

In addition, when the above-mentioned ultrasound characteristics exist alone, the results of judging the benign or malignant nature of nodules are not ideal, but if used in combination, the sensitivity of diagnosis can be greatly improved. Therefore, patients whose color Doppler ultrasound shows that their thyroid nodules are accompanied by two or more of the above-mentioned characteristics should be alert to the possibility of thyroid cancer.

The above is why doctors use B-ultrasound as the main basis for diagnosing thyroid cancer. B-ultrasound is currently the most effective examination item for diagnosing thyroid cancer in China. It is economical, accurate and reliable.
