Iodine-123 (123 I) is a radioactive isotope of iodine used in nuclear medicine imaging, including single-photon emission computed tomography (SPECT) or SPECT/CT exams.

2022年9月23日 · I-123 is the usual form used to diagnose thyroid problems since it does not damage cells. I-123 can be used to perform a thyroid uptake and/or scan. You will take I-123 on the first day and come back the next day for the scan.

2023年7月31日 · The radioactive iodine uptake (RAIU) test is used to quantitate the overall metabolism and kinetics of iodine in the thyroid gland by measuring how much orally ingested iodide is concentrated in the thyroid gland. Iodine-123 (I …

2024年4月23日 · Iodine-123 (I123 or I-123) is a radioisotope of the element iodine (atomic number 53) used in nuclear medicine imaging including to scan the thyroid gland. Iodine-123 is produced in a cyclotron by bombarding Xenon-124 with a proton.

2024年10月27日 · Thyroid scintigraphy (thyroid scan) is a nuclear medicine examination used to evaluate thyroid tissue. Medications that interfere with thyroid uptake of radioiodine should be discontinued. Medications such as amiodarone, potassium iodide and some vitamin supplements should be ceased if safe to do so prior to scan.

2021年10月14日 · Iodide I-123 (as sodium Iodide I-123) is a radioactive isotope of iodine used in nuclear medicine for the diagnostic study of thyroid disease. Following oral administration, I-123 is absorbed through the gastrointestinal tract and is taken up by the thyroid gland.

Iodine-123 (I-123) is a radioactive isotope of iodine with a half-life of approximately 13.2 hours. It decays by electron capture to tellurium-123, emitting gamma radiation with a characteristic energy of 159 keV, which is ideal for medical imaging.

2024年12月9日 · Ioflupane I-123 is a radioactive agent that allows images of the brain to be detected by a gamma camera. Ioflupane I-123 is used to detect brain signs of Parkinson's disease in people with symptoms such as tremors, loss of balance or coordination, shuffling walk, or other movement problems.

Direct parent isotope is: 123 Xe. The gamma emitting isotope iodine-123 is used in nuclear medicine as a radioactive imaging tracer to assess the anatomical location and physiological function of the thyroid gland.

2015年11月30日 · Iodide I-123 (as sodium Iodide I-123) is a radioactive isotope of iodine used in nuclear medicine for the diagnostic study of thyroid disease. Following oral administration, I-123 is absorbed through the gastrointestinal tract and is taken up by the thyroid gland.
