Methods 6 patients with repaired ALCAPA (2 Tackeuchi, 4 direct re-implantation) underwent CMR to assess clinical suspicion of myocardial ischemia short axis and long axis cine images (assess ventricular function), late-gadolinium enhancement (detect myocardial fibrosis), adenosine stress perfusion scan (detection of reversible ischaemia) and 3D whole-heart imaging (visualization of proximal cor...

introduction: nowadays, imaging of the myocardial perfusion (mpi) using the single photon emission tomography (spet) in the diagnosis of coronary artery disease, especially myocardial ischemia, is of great importance. in contrast to the coronary artery angiography, mpi is non-invasive, less expensive and more physiological. unfortunately, this image is affected by the some artifacts. these arti...

dextrocardia is a cardiac positional anomaly in which the heart is located in the right hemithorax with its base-to-apex axis directed to the right and caudad. situs inversus is an autosomal recessive disorder that causes organs in the chest and abdomen to be positioned in a mirror image from their normal position. dextrocardia may occur in isolation or as part of situs inversus. similarly, sit...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...

Background The quest to quantify myocardial perfusion has been largely motivated by the desire to obtain quantitative, observer-independent, and reproducible measures of myocardial perfusion. Spiral pulse sequences have multiple advantages for myocardial perfusion imaging including high acquisition efficiency, high signal to noise (SNR) and robustness to motion. We have developed a spiral pulse...

AIMS We analyzed the usefulness of quantitative intravenous myocardial contrast echocardiography to study microvasculature perfusion after infarction in comparison with intracoronary myocardial contrast echocardiography. METHODS AND RESULTS Thirty-two patients with a first ST elevation myocardial infarction, single-vessel disease and an open artery (TIMI 3) were studied before discharge. Myoc...

fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. to increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. in 46 patients (48.8%) fixed perfusion ...

UNLABELLED Although human interpretation of (99m)Tc-sestamibi SPECT myocardial perfusion imaging has been repeatedly validated in the diagnostic and prognostic assessment of coronary artery disease, it remains unclear if automated computer-derived quantitative indices of perfusion have similar or independent prognostic information. METHODS We studied 718 patients referred for (99m)Tc-sestamib...

BACKGROUND Appropriate use criteria (AUC) have been developed to aid in the optimal use of single-photon emission computed tomography (SPECT)-myocardial perfusion imaging (MPI), a technique that is a mainstay of risk assessment for ischemic heart disease. The impact of appropriate use on the prognostic value of SPECT-MPI is unknown. METHODS AND RESULTS A prospective cohort study of 1511 conse...
