Quantification 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 کاملMyocardial perfusion SPECT: Perfusion quantification
Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically. Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...
متن کاملAdenosine 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 کاملFusion of 3D-CMR-perfusion with 3D-MR-coronary angiography
Background The most relevant parameters for the assessment of coronary artery disease (CAD) are myocardial perfusion and the status of the coronary arteries. It has been shown that hybrid imaging strategies to acquire both parameters such as SPECT with CT-angiography provide an added value for clinical decision making in the treatment of CAD. However, SPECT and CT expose the patient to ionizing...
متن کاملDirect comparison of CMR dobutamine stress wall motion and perfusion analysis with adenosine perfusion in patients after bypass surgery
Methods One hundred nine patients (93 men, 65±8 years, BMI 28.7±3.3) after CABG underwent CMR imaging on two appointments. 1) LV-function, DSMR (10-40μg/kg/min + 2mg atropine if needed until target heart rate) imaging (SSFP) of 3 short axis (apical, medial, basal) and 3 long axis views at each stress level. Perfusion imaging of 3 short axis (SSFP, TR/TE 2.8 ms/1.4 ms, FA 50°, SENSE-factor 3.0) ...
