Visualizing hyperparathyroidism: A pictorial essay of Tc-99m MIBI parathyroid imaging across different etiologies

Abstract Parathyroid scintigraphy is an imaging technique that uses gamma-emitting radionuclide to locate hyperfunctioning parathyroid glands in patients with hyperparathyroidism. It valuable for preoperative assessment before parathyroidectomy, which a curative surgery most cases of primary hyperparathyroidism and some secondary There are several different techniques scintigraphy. In general, the performed Tc-99m MIBI, mitochondria-targeting radiotracer. Some also supply MIBI thyroid differentiate between tissue. can detect sensitivity 80% specificity 84%. 58% 93%.
