Thyroid ultrasonography is usually painless. Thyroid ultrasonography differs from a regular thyroid ultrasound in that it involves an intravenous injection into an elbow vein.
Thyroid ultrasonography is an intravenous injection of 1.5-2 milliliters of contrast material on top of a regular ultrasound exam, which can identify benign and malignant lesions, and the entire procedure is fairly short, and can be completed in a few minutes. It is a new imaging technique that is non-invasive, free of ionizing radiation, safe, fast, and has very high diagnostic accuracy.
The thyroid tissue will absorb the contrast agent after injection and then develop under imaging, which can observe the blood supply in the thyroid gland and provide a basis for diagnosing thyroid diseases, as well as initially determine the benign or malignant nature of the nodules, and it is also a relatively safe and easy-to-operate examination.
Patients who need to undergo thyroid ultrasonography need not worry about pain and should relax and cooperate with the doctor.
