Ultrasonography of the thyroid and parathyroid glands

Ultrasound examination of the thyroid and ultrasound of the parathyroid gland were performed by B-mode ultrasonography on the thyroid gland and parathyroid glands. Thyroid thickness (anterior and posterior diameter) and width (left and right diameter) standard measurement section: Select the thickest and widest part of the thyroid gland in a series of cross-sections of the thyroid gland as the standard section, and the probe pressure should be as light as possible. Measurement position: Select the edge of the high echo line of the capsule at the thickest and widest points of the thyroid. Normal adult reference value (cm): the thickness of the left and right leaves is 1.5~2.0cm, the width is 2.0~2.5cm, and the thickness of the isthmus is less than 0.5cm. Basic Information Specialist classification: growth and development check classification: ultrasound Applicable gender: whether men and women apply fasting: not fasting Tips: It is best not to eat too much before checking, and don't drink too much water. Normal value (1) Thyroid thickness (anterior and posterior diameter) and width (left and right diameter) The standard measurement section selects the thickest and widest part of the thyroid gland as a standard section in a series of cross-sections of the thyroid. 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 capsule at the thickest and widest points of the thyroid. The normal adult reference value (cm) is about 1.5 to 2.0 cm in thickness and 2.0 to 2.5 cm in width, and the thickness of the isthmus is less than 0.5 cm. (B) the long diameter (upper and lower diameter) measurement of the thyroid The standard measurement section selects the longest part of the thyroid parenchyma as the standard section in a series of longitudinal sections of the thyroid, requiring the probe pressure to be as light as possible. The measurement positions were selected on the edge of the high echo line of the capsule at the longest point of the thyroid gland. Normal adult reference value (cm): the length of the left and right leaves is 4.0~6.0cm, and the length of the isthmus is 1.5~2.0cm. Clinical significance Abnormal result 1. The purpose and significance of ultrasound thyroid (1) Determine whether the tumor is located in the thyroid gland, which is diffuse or localized. (2) Identifying the mass is cystic or solid. (3) Determine whether the mass is single or multiple. (4) It can be judged that the tumor is benign or malignant. (5) The follow-up or post-medication efficacy can be followed up; for the nodules that can not be found, ultrasound can find nodules and nodules >=0.5cm. 2. The sensitivity of ultrasound diagnosis of primary hyperparathyroidism is 66%-88.4%. Color Doppler can not only improve the sensitivity of ordinary two-dimensional ultrasound to the detection of small lesions of the parathyroid gland, but also help to locate the diagnosis and distinguish it from the thyroid and lymph nodes. High results may be diseases: laryngeal stenosis, pediatric chronic lymphocytic thyroiditis, pregnancy with hyperparathyroidism, endemic goiter, chronic fibrotic thyroiditis, thyroid tumor, thyroid cyst precautions Before the test: It is best not to eat too much, and do not drink too much water. When checking: Concentrate on the doctor's operation. Inspection process B-ultrasound examination, the graphics are intuitive and clear, easy to find small lesions, can see the various cut surface graphics of the human body. Early diagnosis of various diseases of the liver, spleen, gallbladder, pancreas, kidney and bladder can be obtained in time. Not suitable for the crowd Inappropriate people: Generally there are no people who are not suitable. Adverse reactions and risks This test generally has no adverse reactions.
