Background Selective venous sampling (SVS) is an invasive localization study for persistent or recurrent hyperparathyroidism. Purpose To assess the role of SVS in addition to non-invasive imaging for primary hyperparathyroidism (pHPT). Material and Methods This study was approved by the institutional review board and included 14 patients who underwent SVS and subsequent parathyroidectomy be...

OBJECTIVES This study investigated whether the technitium-99m sestamibi (MIBI) washout rate (WR) would predict mitochondrial damage and myocardial dysfunction in patients with dilated cardiomyopathy (DCM). BACKGROUND Myocardial mitochondrial damage reduces adenosine triphosphate production, resulting in myocardial dysfunction. Increased myocardial (99m)Tc-MIBI washout is reportedly caused by ...

Treglia et al. [1] have recently proposed a meta-analysis evaluating the diagnostic performance of 99mTc-MIBI scan in predicting the malignancy of thyroid nodules. 99m-Tc is registered and adopted worldwide for myocardial perfusion imaging and for the diagnostic work-up of hyperparathyroidism. Furthermore there are reports on the use of 99mTc-MIBI imaging in post-surgical evaluation of thyroid ...

OBJECTIVE To compare the value and limitations of exercise testing, dipyridamole echocardiography, dobutamine-atropine echocardiography, and MIBI-SPECT (technetium-99m methoxyisobutyl nitrile single photon emission computed tomography) during dobutamine infusion in the diagnosis of coronary artery disease. DESIGN The performance of these four tests was assessed in random order on a consecutiv...

This work aims to analyze the influence of aminophylline in the pulmonary and hepatic uptake of 99mTc-methoxyisobutil isonitrile (99mTc-MIBI). 72 patients were studied and a myocardial perfusion (MPS) single photon emission computed tomography (SPECT) with 99mTc-MIBI was carried out after the administration of dipyridamole. According to the MPS, the patients were classified into 2 groups: Group...

AIMS AND BACKGROUND The aim of this study was to evaluate the potential contribution of Tc-99m-MIBI scintigraphy to the follow-up of patients with differentiated thyroid carcinoma, who had elevated Tg levels and negative I-131 whole-body scan results. MATERIALS AND METHODS In this retrospective study, we evaluated 28 patients with differentiated thyroid carcinoma, who had total or near total ...

Purpose: Tc-99m-MIBI accumulates in only viable cells. In patients with bone and soft tissue sarcomas, preoperative chemotherapy is essential and the early prediction of the tumor response to chemotherapy would be beneficial for the planning of treatment strategy. The purpose of this study was to assess whether the change of Tc-99m-MIBI image from pre-chemotherapy to the early to middle of the ...
