Thyroid imaging

Thyroid imaging is the preferred method of examination for thyroid disease. 1 hypothyroidism: chronic thyroiditis, cretinism, iodine organic disorders, pituitary hypothyroidism. 2 normal thyroid function: TBG (thyroxine globulin) reduction (familial), nephrotic syndrome, artificial dialysis treatment, hypoproteinemia, protein loss gastrointestinal disease, cirrhosis, drugs (testosterone, protein differentiation hormone , adrenal glucocorticoids, salicylic acid, phenytoin, lenidine, heparin). 3 low T3 syndrome (severe), thyroid poisoning, taking T3 excess. Basic Information Specialist Category: Inspection Category: Radionuclide Applicable gender: whether men and women apply fasting: fasting Tips: iodine should be strictly prohibited before inspection. Normal value normal. Clinical significance Abnormal results: 1. Raise 1 thyroid poisoning painless thyroiditis, subacute thyroiditis, exophthalmia hyperthyroidism, thyroid preparations, teratoma, malignant chorionic epithelioma, pituitary thyroid stimulating hormone tumor. 2 normal thyroid function TBG (thyroid-binding globulin) increase (familial), pregnancy, neonatal, part of liver cancer, hepatitis (acute phase), acute intermittent porphyria, drugs (steroids, birth control pills), anti-thyroid Chronic thyroiditis positive for positive antibody, familial abnormal albuminemia, pre-existing albumin (TBPA), transient hypertonic T4 (acute disease, oral gallbladder contrast agent). 2, lower 1 hypothyroidism chronic thyroiditis, cretinism, iodine organic disorders, pituitary hypothyroidism. 2 normal thyroid function TBG (thyroxine globulin) reduction (familial), nephrotic syndrome, artificial dialysis treatment, hypoproteinemia, protein loss gastrointestinal disease, cirrhosis, drugs (testosterone, protein differentiation hormone, Adrenal glucocorticoids, salicylic acid, phenytoin, lenidine, heparin). 3 low T3 syndrome (severe), thyroid poisoning, taking T3 excess. 3, T4 type hyperthyroidism (T4 increased and T3 normal). People who need to check: Cirrhosis of the liver, excessive sweating, yellowing of the skin, rough skin, hyperthyroidism, hypothyroidism. Low results may be diseases: hyperthyroidism, thyroid neoplasms, thyroid nodules, calcification results may be high in the elderly : subacute thyroiditis, sporadic goiter in children, thyroid gland cysts and sputum, thyroglossal cysts and fistula attention matter Before inspection: The patient's preparation before the scan was the same as the thyroid 131I functional test. Because the dose of radionuclide used for thyroid scanning is larger than that of the 131I functional test, the scan should be performed after all tests. If a scan has been performed, the 131I functional test should be performed 2 to 3 months after the scan. Before the imaging, the iodine ban should be clarified and the drugs that block the function of thyroid 131I should be stopped. If you need to perform 131I test for thyroid gland during the same period, you should take the 131I test first. When checking: During the imaging period, the patient should not be swallowed and the position should remain unchanged. If you suspect that the iodine deficiency is insufficient or the thyroid gland is blocked, you should strictly check the iodine and check it. Inspection process 1. Forbidden food preparation before iodine and oral tracer was measured with 131I rate of thyroid. 2. High-energy, pinhole collimator should be used; the distance between the collimator and the thyroid should be fixed to ensure the same amplification effect at different inspections. 3. The patient takes the supine position and leans back to fully expose the thyroid gland. The imaging range should include the incision from the mandibular angle to the sternum. In the case of an ectopic thyroid, the imaging detection range can be expanded as needed. 4. After the imaging is completed, mark the sternal incision site with the point source, or other clear surface anatomical landmarks, and the thyroid nodules are marked with the location.
