Artifact-free Non-ECG-Gated First-Pass Myocardial Perfusion MRI: Continuous Acquisition for All-Systolic Imaging
INTRODUCTION: First-pass perfusion (FPP) cardiac MR (CMR) imaging has been shown to have a high performance for diagnosis of coronary artery disease (CAD). Reliability of FPP imaging, however, is hindered by dark-rim artifacts (DRAs) and the need for nearperfect ECG gating. The latter can be challenging in the presence of arrhythmias or heart-rate variations during stress. Moreover, endsystolic...
متن کاملEvaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy
Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
متن کاملDiagnostic accuracy of rest/stress ECG-gated Rb-82 myocardial perfusion PET: comparison with ECG-gated Tc-99m sestamibi SPECT.
BACKGROUND Although single photon emission computed tomography (SPECT) and positron emission tomography (PET) myocardial perfusion imaging (MPI) have evolved considerably over the last decade, there is no recent comparison of diagnostic performance. This study was designed to assess relative image quality, interpretive confidence, and diagnostic accuracy by use of contemporary technology and pr...
متن کاملNicorandil effect on myocardial perfusion in patients with slow coronary flow phenomenon assessment by gated myocardial perfusion SPECT
Introduction:Patients with the coronary slow flow phenomenon (SCF) frequently experience angina episodes. The purpose of this study was to determine efficacy of nicorandil in myocardial perfusion in patients with SCF. Methods: Twenty patients (50.85 ± 12.96 y) with SCF were studied. We evaluate coronary slow flow according to protracted thrombolysis in m...
متن کاملComparison of ECG-gated rectilinear vs. real-time radial K-space sampling schemes in cine True-FISP cardiac MRI.
PURPOSE To compare three k-space sampling schemes in cine True-FISP cardiac magnetic resonance imaging and to evaluate changes in calculated quantitative functional cardiac parameters as a function of underlying k-space sampling techniques. MATERIAL AND METHODS Using a 1.5 T MR imaging system (Magnetom Sonata, Siemens Medical Solutions, Erlangen, Germany), three k-space data-sampling schemes:...
