BACKGROUND Infarct size is an important predictor of cardiac risk after acute myocardial infarction. The established modality for its assessment is Tc99m-Sestamibi Single-photon emission computed tomography (SPECT). In recent years, data are emerging demonstrating that scar size as assessed by late gadolinium enhancement in cardiovascular magnetic resonance imaging (CMR) as well as the presence...

BACKGROUND AND PURPOSE The clinical impact of facet joint bone scan activity is not fully understood. The hypothesis of this study is that facet joints targeted for percutaneous treatment in clinical practice differ from those with reported activity on technetium Tc99m methylene diphosphonate SPECT/CT. MATERIALS AND METHODS All patients with a technetium Tc99m methylene diphosphonate SPECT/CT...

BACKGROUND Controversy persists as to the need for both MIBG and bone scanning in routine evaluation of neuroblastoma. AIM To compare the efficacy of I-131- metaiodobenzylguanidine (MIBG) scan against that of conventional Tc99m- methylene diphosphonate (MDP) bone scan for the detection of skeletal deposition of neuroblastoma. METHODS AND MATERIAL The study included 57 patients (36 boys, 21 ...

Introduction: The purpose of this study is to assess the integrated role of scintigraphy by Tc99m MIBI in diagnosis of parathyroid adenoma and its impacts on the myocardium, and to evaluate whether myocardium perfusion gated SPECT study could be a complementary routine workup for patient with positive parathyroid adenoma on Tc99m MIBI parathyroid scan. Methods: Rest myocardium perfusion gated S...

BACKGROUND Lymph node status is the most important prognostic indicator in breast cancer in recently diagnosed primary lesion. As a part of an interregional protocol using scintimammography with Tc99m compounds, the value of planar Tc99m sestamibi scanning for axillary lymph node evaluation is presented. Since there is a wide range of reported values, a standardized protocol of planar imaging w...

In the title compound, [Au(2)Ba(NCS)(4)(C(20)H(24)O(6))](n), the dithio--cyanato-aurate(I) anion adopts a dimeric structure with an Au⋯Au distance of 3.1109 (10) Å; both Au(I) atoms are also bonded to two S atoms. The Ba(II) ion adopts an irregular BaN(3)O(6) geometry, arising from the crown ether and three adjacent thio-cyanate N atoms; the extended structure of the complex can be described as...

The title complex, bis-(μ-benzene-18-crown-6)-3κ(6)O:4κO;4κ(6)O:3κO-bis-(benzene-18-crown-6)-1κ(6)O,6κ(6)O-tetra-μ-thiocyanato-1:2κ(2)S:N;2:3κ(2)N:S;4:5κ(2)S:N;5:6κ(2)N:S-dithio-cyanato-2κN,5κN-2,5-dicopper(I)-1,3,4,6-tetra-potassium(I), [K(4)Cu(2)(NCS)(6)(C(16)H(24)O(6))(4)] or {[K(C(16)H(24)O(6))](4)[Cu(NCS)(3)](2)}, consists of four [K(benzene-18-crown-6)](+) cations and two [Cu(NCS)(3)](2-)...

Introduction: We aimed to investigate of effect of left bundle branch block (LBBB) on perfusion and functional parameters in dipyridamole Tc99m-MIBI gated myocardial perfusion SPECT which may be helpful in interpretation of myocardial perfusion imaging. Methods: We studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with LBBB and  35 subject...
