What is thyroid scanning?

thyroid scanning, also called thyroid scanning and radioactive iodine absorption test or simply thyroid absorption test, is a type of nuclear display test. During this test, a small amount of radioactive material is used to diagnose thyroid diseases. The test itself is simple, but must be performed for two days to obtain accurate thyroid information. In the case of the thyroid absorption test, the radioactive iodine material is used. A few hours before scanning, the patient uses a carefully measured amount of radioactive iodine and this material is used in the body as normal iodine. The material is accepted by the thyroid gland and can then be assessed by a device that detects radioactive material.

Thyroid scanning is used to determine whether the thyroid gland works normally. Undoked or excessive thyroids up less or more iodine, respectively, and this can be detected by scan. Scanning of thyroid absorption can also detect a largeStitter glands and whether there were some lumps in the gland that could indicate the presence of cancer.

Before submitting the thyroid scanning, the patient should ensure that his doctor has a full history. This includes information about the drugs that the patient is taking and whether they have any allergies. Women who are pregnant or breastfeeding should inform their doctor because scanning can be harmful to fetal development.

The

thyroid scan is performed in three phases. The first phase is swallowing a small pill that contains radioactive iodine. To se obvykle provádí ráno. Between four and six hours later, scanning is carried out to detect the stop radioactive iodine in the thyroid. The third and last phases, the second Thyroid Scan, is done the next day.

During the scan, the patient lies on his back under the scanning device. The device is calibrated to detect radioactive iodine and passes over the pacENTA to detect the location of the radioactive iodine in the body. This information is then transferred to a computer that generates thyroid images, showing where iodine is located. These images can be interpreted by a doctor to determine the size of the gland and how well it works.

There are some risks associated with the scanning of thyroid absorption. The radiation risk is extremely low because the amount of radioactive iodine used is minimal. The greatest risk to the patient is the risk of allergies to medicines used in the procedure. There is another risk of child damage or breastfeeding in women.
