Adenosine stress perfusion CMR accurately identifies the culprit vessel
Background The diagnostic evaluation of patients with suspected ischaemic heart disease (IHD) frequently involves a functional assessment of ischaemia. Adenosine stress perfusion CMR is a non-invasive test with high sensitivity for the detection of IHD, however rarely is its accuracy for culprit vessel identification assessed. We sought to determine the accuracy of stress perfusion CMR for iden...
متن کاملAdenosine stress CMR with spiral pulse sequences accurately detect CAD
Background Adenosine stress perfusion imaging with CMR has been limited by motion-induced dark-rim artifacts, which may be mistaken for true perfusion abnormalities. We have previously demonstrated that spiral pulse sequences can produce high quality first-pass perfusion images.[1] We have further improved this spiral technique using high-resolution variable density spiral trajectories and a no...
متن کاملQuantification of perfusion defects with high resolution 2D and 3D adenosine stress perfusion 3.0 Tesla CMR
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 myocar...
متن کاملAdenosine stress perfusion CMR in young children: assessment of optimal imaging parameters
Background Adenosine stress perfusion CMR is commonly used for assessing coronary artery disease (CAD) in adults. CAD is uncommon in children, but does occur. There is limited experience performing adenosine stress perfusion CMR in young children. Performing stress perfusion CMR in young children presents a number of technical imaging challenges. Specific Aim: Evaluate image quality and optimal...
متن کاملDiagnostic Accuracy of Adenosine Stress Cardiovascular Magnetic Resonance Following Acute ST-segment Elevation Myocardial Infarction Post Primary Angioplasty
BACKGROUND Adenosine stress cardiovascular magnetic resonance (CMR) has been proven an effective tool in detection of reversible ischemia. Limited evidence is available regarding its accuracy in the setting of acute coronary syndromes, particularly in evaluating the significance of non-culprit vessel ischaemia. Adenosine stress CMR and recent advances in semi-quantitative image analysis may pro...
