99Tmc-MIBI Thyroid Imaging

99Tmc-MIBI thyroid imaging was performed according to the following principles. 99Tmc-MIBI can be taken up by hyperactive parathyroid tissue and also by thyroid tissue, which is cleared from the thyroid gland faster than the parathyroid gland. Early imaging and delayed imaging were performed, and images of the parathyroid glands were analyzed by comparing changes in the two images. Early imaging was performed after intravenous injection of 99Tmc-MIBI370MBq (10mCi) for 15-20min, and delayed imaging was performed after 2 hours. Basic Information Specialist Category: Inspection Category: Nuclear Magnetic Resonance Applicable gender: whether men and women apply fasting: fasting Tips: Pay attention to normal diet and work before check to prevent endocrine disorders. Normal value No agglomeration of adenomas was seen, only normal thyroid images. Clinical significance It is used to identify functional autonomic thyroid tumors and congenital one-leaf thyroid gland. In normal thyroid imaging, if the normal thyroid tissue function is completely inhibited or not developed, only the agglomeration of the adenoma can be seen. The 99Tmc-MIBI imaging normal thyroid can take 99Tmc-MIBI and develop, so the adenoma group Thyroid imaging occurs outside the visceral shadow; if the congenital lobular thyroid is absent, the images of conventional thyroid imaging and 99Tmc-MIBI imaging are similar. Abnormal results: 1. The early manifestation of thyroid tumor is a painless mass in the anterior cervical region, mostly single, round, elliptical or nodular, with different sizes, clear boundary, medium hardness, smooth surface and good activity. Swallow up and down. Because of no discomfort, it was mostly jujube-sized when found. Sometimes the tumor can suddenly increase, accompanied by pain and discomfort, mostly caused by intratumoral cystic hemorrhage. Very few large adenomas can cause tracheal compression, but compression of the recurrent laryngeal nerve is extremely rare. 2. Congenital one-leaf thyroid deficiency is a very rare form of thyroid hypoplasia with a low incidence. 1 due to the absence of the thyroid gland, the volume of the thyroid gland is reduced, the body in order to maintain sufficient thyroxine levels, especially in adolescence. Compensatory mechanism will promote contralateral thyroid hyperplasia, so the goiter will occur. There may even be Graves' disease or Graves' disease, etc.; 2 At the same time, due to the lack of unilateral thyroxine secretion, there may be hypothyroidism. People who need to be examined: Patients with suspected thyroid tumors and congenital one-leaf thyroid gland. Precautions Forbidden before examination: pay attention to normal diet, pay attention to normal work and rest, and prevent endocrine disorders. Requirements for inspection: Actively cooperate with the doctor's request. Inspection process Methods: Early imaging was performed after intravenous injection of 99Tmc-MIBI370MBq (10mCi) for 15-20min, and delayed imaging was performed after 2 hours. Not suitable for the crowd Inappropriate crowd: temporarily unknown. Adverse reactions and risks Nothing.
