we use 99mTc-MIBI in functional studies of the parathyroid gland? Nephrol Dial Transplant

Abstract. The usefulness of technetium-99m-sestamibi Key words: chronic renal failure; haemodialysis; 99mTc-MIBI parathyroid scintigraphy; parathyroid(99mTc-MIBI) in patients with secondary hyperpara-thyroidism on haemodialysis was assessed. We studied hyperplasia; secondary hyperparathyroidism 33 patients with parathyroid scintigraphy with i.v. (99mTc-MIBI). Static images in a scintillation camera were taken at 15 and 120 min after the injection. With IntroductionP×Ca<80, we performed an inhibition test with calcitriol i.v. 2 mg, three times a week, for 2 weeks. The understanding of pathogenic mechanisms in sec-The MIBI study and assessment of intact parathyroid ondary hyperparathyroidism has progressed in recenthormone (iPTH) were performed before (baseline years [1–3]. Radioisotopic techniques, like otherstudy) and after inhibition. A ‘focal positive study
