Synthesis of novel magnetic multicore particles (MCP) in the nano range, involves alkaline precipitation of iron(II) chloride in the presence of atmospheric oxygen. This step yields green rust, which is oxidized to obtain magnetic nanoparticles, which probably consist of a magnetite/maghemite mixed-phase. Final growth and annealing at 90°C in the presence of a large excess of carboxymethyl dext...
Abstract Funding Acknowledgements Type of funding sources: None. Introduction Data supporting the role stress test myocardial perfusion imaging (MPI) before non-cardiac surgery (NCS) are sparse and out date. In particular, there is no specific evidence on use cardiac magnetic resonance (sCMR) in this setting. The aim present study was to evaluate impact MPI with sCMR single-photon emission comp...
In the last decade, positron emission tomography (PET) myocardial perfusion imaging (MPI) has emerged as a valuable clinical tool for the management of patients with known or suspected coronary artery disease (CAD). Compared with singlephoton emission computed-tomography (SPECT), PET provides higher-quality images and superior diagnostic accuracy (1). Increased availability of PET scanners, Med...
Background We previously introduced a model-based approach (Decisions Informed by Computed Entities [DICE]), a mathematical form of Artificial Intelligence (AI) to improve prognostic values of quantitative myocardial perfusion imaging (MPI). When DICE was applied to cardiovascular MRI (CMR) it improved prediction of MACE in women with suspected ischemic heart disease (IHD) compared to the conve...
BACKGROUND Magnetic particle imaging (MPI) is a new tomographic imaging technique capable of imaging magnetic tracer material at high temporal and spatial resolution. Image reconstruction requires solving a system of linear equations, which is characterized by a "system function" that establishes the relation between spatial tracer position and frequency response. This paper for the first time ...
The aim of this study was to evaluate the mid-term clinical status of patients following tetralogy of Fallot (TOF) repair. We performed a cross-sectional observational analysis of 57 postoperative TOF patients and 58 age-matched controls. Patients were examined with myocardial performance index (MPI), which was obtained by tissue Doppler imaging (TDI) in addition to the conventional methods. Co...
OBJECTIVES The coronary artery calcium (CAC) score has been shown to predict future cardiac events. However the extent to which the added value of a CAC score to the diagnostic performance of myocardial perfusion imaging (MPI) by single photon emission computed tomography (SPECT) is unclear. The purpose of this study is to investigate the correlation between CAC score and SPECT in patients with...
OBJECTIVE Investigations of Appropriate Use Criteria (AUC) education have shown a mixed effect on changing provider behaviour. At our facility, rarely appropriate myocardial perfusion imaging (MPI) differs by specialty; awareness of AUC is low. Our objective is to investigate if specialty-specific, multimodality education could reduce rarely appropriate MPI. METHODS We designed education focu...
Myocardial perfusion imaging (MPI) is commonly used to detect ischemia. Concerns about silent ischemia may encourage orders for MPI in asymptomatic patients. Factors contributing to this practice are poorly described and the clinical utility is questionable.We conducted a single center retrospective cohort investigation on Veterans who underwent MPI between December 2010 and July 2011. We gathe...
BACKGROUND Stress nuclear myocardial perfusion imaging (MPI) is an established method for diagnosis and prognosis of coronary artery disease (CAD). However, radiation exposure limits its clinical application. Magnetocardiography (MCG) has been proposed as a non-contact, rapid and non-radiation technique with high reproducibility. The aim of the study was to evaluate the diagnostic efficacy of r...
