What is the scanning of the thyroid gland of nuclear medicine?
Nuclear Medicine Thyroid is a diagnostic tool used to determine the function of the thyroid gland. The test is necessary to detect a number of conditions, including hyperthyroidism, goiter and thyroid cancer. The test requires the patient to consume a small amount of radioactive iodine before testing. The procedure only takes minutes and causes only small or no discomfort to the patient.
The diagnosis of a specific disorder is required to scan the thyroid gland of nuclear medicine. Unlike other forms of medical imaging, such as MRI or PET scanning, nuclear medicine scans have the advantage of showing a metabolic function in real time. For the scanning of the thyroid gland, the scanning measures the speed at which the thyroid absorbs iodine.
clock before scanning, the patient takes a pill containing a small amount of radioactive iodine, a hitchhiker that scdetets. The body thatIt cannot distinguish the tracing machine from normal iodine, sends it to the thyroid gland to process the thyroid hormones. The test can accurately measure the thyroid function only when this process takes place.
The first scan takes place about four to six hours after the patient enjoys radioactive iodine. It lies on the table, the display scanner is located directly above its neck. The scanner records only a few minutes and records radioactivity emitted by the iodine indicator that traveled to the thyroid gland. In a healthy adult scanner creates a thyroid image as a shaded area against a white background. Even shading indicates normal iodine intake.
, regardless of the result of the first test, a second is usually done 18 hours later. Comparison of these two images gives each other a detailed view of the thyroid function. If the thyroid image is particularly dark, it is knownka hyperthyroidism; The thyroid gland is excessive. An unusually light image occurs as a result of hypothyroidism. An enlarged or erroneous thyroid indicates the presence of a tumor or goiter.
If abnormalities appear in the results of nuclear thyroid medicine, other diagnostic tools are necessary to make a final diagnosis. For example, a tumor and a goiter can create a similar image when scanning. In these cases, the surgeon performs a biopsy to determine the nature of the matter.
