Sodium Iodide I 123
Sodium iodide I-123 is a radioactive iodine isotope used for diagnostic thyroid scintigraphy and thyroid uptake measurements, providing high-resolution gamma camera imaging with lower radiation dose compared to iodine-131. The iodide ion is selectively concentrated by thyroid follicular cells via the sodium-iodide symporter, allowing assessment of thyroid morphology, function, and nodule characterization. Iodine-123 emits gamma photons at 159 keV with a 13.2-hour half-life optimal for diagnostic imaging.
