Normal thyroid ultrasound values

The thyroid tissue can be examined in a number of ways, and there are many things that should be examined about the thyroid, including some ultrasound examinations. There is a certain normal range for thyroid ultrasound, and there are also many ways to examine it. However, there are also many abnormalities in thyroid ultrasound. So what is the normal value for thyroid ultrasound?

The standard measurement section for the thickness (anteroposterior diameter) and width (lateral diameter) of the thyroid gland is the thickest and widest part of the thyroid parenchyma among a series of cross-sections of the thyroid gland, and the probe pressure is required to be as light as possible. The measurement positions were selected at the edges of the hyperechoic lines of the thyroid capsule at the thickest and widest parts. The reference value for normal adults (cm) is that the thickness of the left and right lobes is 1.5~2.0cm respectively, the width is 2.0~2.5cm, and the thickness of the isthmus is less than 0.5cm.

The standard measurement section for measuring the long diameter (superior and inferior diameter) of the thyroid gland is to select the longest part of the thyroid parenchyma as the standard section from a series of longitudinal sections of the thyroid gland, and the probe pressure is required to be as light as possible. The measurement positions were selected on the edge of the hyperechoic line of the thyroid capsule at the longest part. Reference values ​​for normal adults (cm): The lengths of the left and right lobes are 4.0~6.0cm respectively, and the length of the isthmus is 1.5~2.0cm.

Abnormal results: (1) Determine whether the tumor is located in the thyroid gland and whether it is diffuse or localized; (2) Differentiate whether the tumor is cystic or solid; (3) Determine whether the tumor is single or multiple; (4) Determine whether the tumor is benign or malignant; (5) Follow up the efficacy of surgery or medication. For nodules that cannot be palpated, ultrasound can detect nodules >= 0.5 cm and the number of nodules.

The sensitivity of ultrasound in diagnosing primary hyperparathyroidism is 66% to 88.4%. Color Doppler ultrasound can not only improve the sensitivity of ordinary two-dimensional ultrasound in detecting small parathyroid lesions, but also help with positioning diagnosis and make it easier to distinguish them from thyroid and lymph node tumors.

People who need to be examined: those with goiter, thyroiditis, thyroid tumor, thyroid cyst, cervical lymphadenopathy, parathyroid adenoma and parathyroid hyperplasia, multiple endocrine neoplasms, parathyroid cancer, etc.
