What Is Ultrasonography (USG)?
Ultrasonography, also called USG or ultrasound, is a safe and painless test. It uses sound waves to create pictures of the inside of your body. Doctors often use it to look at organs, tissues, and blood flow. Because it does not use radiation, it is safe for most people. Many clinics offer this test, so you may find a “thyroid ultrasound near me” easily.
What Are Thyroid Nodules?
Thyroid nodules are small lumps that form in the thyroid gland. The thyroid is a butterfly-shaped gland in your neck. Most nodules are not cancer. However, some can cause problems or need treatment. For this reason, doctors often check them with tests like ultrasonography for thyroid nodules.
Why Is USG Important for Thyroid Nodules?
USG is very helpful for finding and checking thyroid nodules. First, it helps doctors see the size, shape, and number of nodules. Next, it shows if a nodule is solid or filled with fluid. Also, USG can help guide a needle if a sample is needed. Because of these reasons, USG is the main tool for thyroid nodule diagnosis.
How Is a Thyroid USG Performed?
During a thyroid USG, you will lie on your back. The doctor or technician will put a small amount of gel on your neck. Then, they will move a small device called a transducer over the area. This device sends sound waves into your neck and picks up the echoes. The machine turns these echoes into pictures on a screen. The whole thyroid ultrasound procedure usually takes about 15 to 30 minutes.
What to Expect During the Procedure
Most people find the thyroid USG scan easy and comfortable. You will not feel pain. However, you may feel a little pressure from the transducer. The gel may feel cool on your skin. After the test, you can go back to your normal activities right away. Because there is no radiation, it is safe for children and pregnant women too.
How to Prepare for a Thyroid USG
Usually, you do not need to do much to get ready for a thyroid USG. Still, here are a few tips:
Because the test is simple, you can eat and drink as usual before your appointment.
What Do the Results Mean?
After the scan, a doctor will look at the pictures. They will check the size, shape, and features of any nodules. Sometimes, the doctor may see signs that a nodule is harmless. Other times, they may find features that need more tests. For example, they may suggest a biopsy if the nodule looks unusual. Your doctor will explain what the results mean for you.
