INTRODUCTION A 66-years old man suffering from coronary artery disease appeared without symptoms for routine follow-up in our clinic. CASE DESCRIPTION The echocardiogram revealed a tumorous mass of the right atrium and right ventricle. In the past, coronary revascularization with venous grafts of the right coronary artery and circumflex artery as well as internal mammaria graft to the left an...

This paper presents an image-based classification method, and applies it to classification of cardiac MRI scans of individuals with Tetralogy of Fallot (TOF). Clinicians frequently diagnose cardiac disease by measuring the ventricular volumes from cardiac MRI scans. Interrater variability is a common issue with these measurements. We address this issue by proposing a fully automatic approach fo...

Cardiac diffusion tensor MR imaging (DT-MRI) allows to analyze 3D fiber organization of the myocardium which may enhance the understanding of, for example, cardiac remodeling in conditions such as ventricular hypertrophy. Diffusion-weighted MRI (DW-MRI) denoising methods rely on accurate spatial alignment of all acquired DW images. However, due to cardiac and respiratory motion, cardiac DT-MRI ...

Cine magnetic resonance imaging (cine MRI) was used to evaluate the cardiac structures and blood flow in congenital heart diseases with left-to-right shunts. Fifteen children with left-to-right shunts which were confirmed by echocardiography or angiography were investigated in the present study. Five children each had atrial septal defect, ventricular septal defect, and complete endocardial cus...

a 64-year-old female with history of previous aortoiliac occlusion and aortoiliac bypass operation four months ago presented with dyspnea, ascites and leg edema. she has been suffering from bloody diarrhea since two weeks earlier. laboratory data showed important eosinophilia and stool examination was positive for strongyloides stercoralis. patient had clinical signs of heart failure. a cardiac...

Background Cardiac MRI is useful for evaluation of severity and prognosis of DCM. This can render myocardial scarring in delayed contrast-enhanced MRI, but the scarring is observed only in 30%-40% of DCM cases presenting with congestive heart failure. Because of its binary contrast between the normal myocardium and scarring, delayed contrasenhanced MRI may fail to detect the diffuse myocardial ...

Dynamic changes in cardiac structure and function are usually examined by real-time imaging techniques such as angiography or echocardiography. MRI has many advantages compared with these established cardiac imaging modalities. However, system hardware and software limitations have limited cardiac MRI to gated acquisitions that are lengthy and often result in failed acquisitions and examination...

Since 1948, epidemiology studies played an important role in understanding cardiovascular disease and afforded an opportunity to learn about newer diagnostic tests. In 2000, the MESA Study incorporated several advanced cardiovascular imaging modalities including cardiac magnetic resonance imaging (MRI) and coronary artery calcium scans. The decade of follow-up enabled prognosis studies, an impo...

Transgenic mice with a dysfunctional guanylyl cyclase A gene (GCA -/-) are unable to transduce the signals from atrial naturetic peptide and develop hypertension and cardiac hypertrophy. Magnetic resonance imaging (MRI) was performed to assess cardiac hypertrophy in these animals, using wild-type siblings as controls. Anesthetized mice were studied by gated multislice, multiphase cine MRI at 1....

BACKGROUND Regional assessments of left ventricular (LV) wall motion obtained during MRI cardiac stress tests can be used to identify myocardial injury and ischemia, but the utility of MRI stress test results for the assessment of cardiac prognosis is not known. METHODS AND RESULTS Two hundred seventy-nine patients referred (because of poor LV endocardial visualization with echocardiography) ...
