Quantification of perfusion defects with high resolution 2D and 3D adenosine stress perfusion 3.0 Tesla CMR

چکیده
Background Myocardial ischaemic burden is an important marker of outcome in stable ischaemic heart disease with a 10% ischaemic burden suggested as a clinically relevant threshold for revascularisation. Standard CMR stress perfusion imaging utilises 3 short axis slices, each acquired in different phases of the cardiac cycle. Recently proposed 3D myocardial perfusion CMR allows the entire myocardium to be sampled within the same cardiac phase and therefore should allow more accurate quantification of ischaemic burden without extrapolation. In this study we compared visual ischaemia detection and quantification by 2D high resolution and 3D whole heart myocardial perfusion CMR.

Inter-observer agreement and diagnostic accuracy of myocardial perfusion reserve quantification by cardiovascular magnetic resonance at 3 Tesla in comparison to quantitative coronary angiography
BACKGROUND Quantification of cardiovascular magnetic resonance (CMR) myocardial perfusion reserve (MPR) at 1.5 Tesla has been shown to correlate to invasive evaluation of coronary artery disease (CAD) and to yield good inter-observer agreement. However, little is known about quantitative adenosine-perfusion CMR at 3 Tesla and no data about inter-observer agreement is available. Aim of our study...

Background Cardiac magnetic resonance imaging (CMR) including adenosine perfusion and late gadolinium enhancement (LGE) at 1.5 Tesla (T) has been established for noninvasive detection of relevant coronary artery disease (CAD). However, little is known about the potential advantages of 3.0-T to detect CAD. The aim of our prospective study was to compare a compiled clinical routine CMR protocol p...
