Primary hyperparathyroidism (pHPT) is defined by the excess level of parathyroid hormone (PTH). Parathyroid adenoma is responsible for about 80% of all pHPT. Parathyroid adenoma with cystic feature and atypical pathology is recognized as a rare entity. Technetium-99m methoxy isobutyl isonitrile ([99mTc]Tc-MIBI) scintigraphy has favorable detection rate for ectopic gland as well as th...
Background: Radioguided surgery using 99m-Technetium-methoxyisobutylisonitrile (Tc-MIBI) has been recommended for the surgical treatment of mediastinal parathyroid adenomas. However, high myocardial Tc-MIBI uptake may limit the feasibility of radioguided surgery in aortopulmonary window parathyroid adenoma. Case presentation: Two female patients aged 72 (#1) and 79 years (#2) with primary hyper...
We report the case of a 64-year-old woman who had a severe hypercalcemia. Serum calcium, intact parathyroid hormone (PTH), 1alpha, 25 (OH)(2 )vitamin D(3) levels were all elevated, and serum phosphorus level was decreased, which were all consistent with primary hyperparathyroidism (PHPT). (201)Tl/(99m)Tc subtraction scintigraphy failed to detect any abnormal accumulation in the neck and chest, ...
OBJECTIVE This study was designed to evaluate the correlation between improvements in serial images obtained by SPECT imaging with Tc-99m MIBI (MIBI) and I-123 BMIPP (BMIPP) and the recovery of cardiac function in acute myocardial infarction (AMI) patients after reperfusion therapy. METHODS Twenty five patients who were admitted to the emergency room within 24 hours after the onset of the fir...
INTRODUCTION Scintigraphy with technetium-sestamibi (MIBI) is the test of choice for localising adenomas in patients with primary hyperparathyroidism (PHPT). In some studies it has emerged that the increase in sensitivity of this test could be associated with a decrease in the uptake of the radiotracer by the thyroid gland. The aim of this study is to analyse our experience in patients with a n...
UNLABELLED Our aim was to ascertain the relationship between the degree of 99mTc-MIBI uptake and the level of p-glycoprotein (Pgp) expression determined by flow cytometry and reverse transcription-polymerase chain reaction (RT-PCR) techniques in patients with hematologic malignancy. METHODS A total of 21 samples (19 patients) were evaluated. Two patients had repeat studies after therapy. Thir...
The authors present a case of multiple myeloma with intense hepatic and splenic uptake on Tc-99m HDP bone scan and discuss its clinical implications and possible uptake mechanisms. Tc-99m MIBI and Tc-99m sulfur colloid were used to demonstrate bone marrow involvement and focal lesions of multiple myeloma.
PURPOSE The aim of this study is to evaluate structural alterations of thyroid tissue after microwave ablation using elastography and scintigraphic imaging to investigate the applicability of these diagnostic methods for follow-up. MATERIALS AND METHODS 35 patients with 39 thyroid nodules were evaluated using elastography and scintigraphic imaging before and after ultrasound-guided microwave...
A 34 year old woman with malaise, polyuria and nocturia as well as nausea and vomiting referred to perform a thyroid scan due to right thyroid lobe mass. The scan showed a cold nodule in the right thyroid lobe. Serum calcium of 16.9, serum phosphorus of 1.8 and PTH of 1156 were noticed in laboratory tests. Parathyroid scan with 99mTc-MIBI showed no abnormal tracer activity in the nec...
