Objective: IQSPECT is an advanced high-speed SPECT modality for performing myocardial perfusion imaging (MPI), which uses a multi-focus fan beam collimator with resolution recovery reconstruction. The aim of this study was to compare IQSPECT compared with conventional SPECT interms of performance based on standard clinical protocols. In addition, we examined the concordance between convention...
objective(s): the energy resolution of a cadmium-zinc-telluride (czt) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional anger type detector which is 10%. also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. in this study, we used a semiconductor detector and examined the ef...
INTRODUCTION Delayed-enhancement magnetic resonance imaging (DE-MRI) has been recently proposed as an alternative tool in identifying myocardial viability and transmural distribution of necrosis in the myocardium. CASE PRESENTATION We describe a case of a 71-year-old man admitted for ischemic-like chest pain in which DE-MRI and post-nitrate 99mTc-tetrofosmin myocardial scintigraphy equally co...
Methods CE-MARC was a prospective study of 752 patients with suspected angina. All patients were scheduled for CMR, SPECT and X-ray coronary angiography. Multi-parametric CMR comprised adenosine stress/rest perfusion, cine imaging, late gadolinium enhancement and MR coronary angiography. Gated adenosine stress/rest SPECT was performed using 99mTc-tetrofosmin. The primary outcome was the diagnos...

UNLABELLED 99mTc-Tetrofosmin is a recently introduced radioactive isotope for the assessment of myocardial perfusion. Data regarding the prognostic value of stress imaging using this isotope are scarce. The aim of this study was to assess the prognostic value of dobutamine-atropine (99m)Tc-tetrofosmin SPECT for the prediction of late cardiac events in patients with known or suspected coronary a...
