Pre operative localization is being carried out (in UK) by ultrasonography (USG) (73%), 99 Technetium (TC) Sestamibi
parathyroid scan (82%), Computed Tomography (CT) scan or Magnetic Resonance Imaging (MRI) (5%).
A technetium sestamibi
scan of the patient's myocardium revealed no perfusion defects (Fig.
The MBI uses a chemical compound called sestamibi
, and a special camera that detects tissue activity.
Are additional localization studies and referral indicated for patients with primary hyperparathyroidism who have negative sestamibi
The most common methods used in the imaging of parathyroid adenomas are ultrasonography (USG) and Tc-99m sestamibi
Technetium-99m (Tc-99m) sestamibi
scan revealed an enlarged right superior parathyroid gland.
sicanlarda yaptiklari akut iskemi-reperfuzyon calismasinda I-12515-(p-iodophenyl)-3-R,S-methyl penta decanoic acid (BMIPP), Tl201, Tc-99m sestamibi
kullanarak 3 ajan ile otoradyografik degerlendirme yapmistir (31).
A whole-body Tc99 m sestamibi
parathyroid scan showed an increased tracer concentration in the anterior mediastinum, which suggested the presence of active parathyroid tissue, while the same activity was not observed in the neck.
scan identified a left inferior parathyroid adenoma.
Parathyroid scintigraphy was carried out after the intravenous injection of 450 MBq [sup.99m]Tc-MIBI sestamibi
At the 6th month of follow-up, sestamibi
parathyroid scan showed no abnormality and no residual mass in the right thyroid lobe.
