Background: Although MRI has long been used for cardiac imaging, significant improvements in MRI scanners for cardiac specific pulse sequences have only been commercially available since the late 1990’s. Cardiac MRI is a complex and difficult examination that needs not only state-of-the-art MRI scanners, but also staff that is experienced with performing cardiac MRI studies. The main advantages...

There are many things in life everybody wants more of, and this is particularly true for magnetic resonance imaging (MRI). The major challenge in the daily life of an MRI professional is gaining maximal image signal and contrast in a reasonable amount of time. The application of gadolinium (Gd)-based MR contrast material has offered contrast features in MRI that have been used and appreciated f...

in patients who undergo median sternotomy to treat congenital heart diseases, a thymectomy is performed to yield better access to the cardiac system. in this study we have used mri to evaluate the changes in size, shape and location of the thymus after midsternatomy. this case-control study was performed during 2011-2012 in shiraz, iran. eligible participants between 5-17 years of age were divi...

Background Late gadolinium enhanced (LGE) MRI is the gold standard test for non-invasive detection of myocardial scar. Many VT ablation candidates who would derive benefit from LGE MRI do not undergo cardiac MRI largely due to image artifacts generated by cardiac devices. A recent study reported improved LGE MRI for patients with implantable cardiac devices using a custom-made wideband adiabati...

OBJECTIVES The purpose of this study was to validate cardiac measurements derived from real-time cardiac magnetic resonance imaging (MRI) as compared with well-validated conventional cine MRI. BACKGROUND Although cardiac MRI provides accurate assessment of left ventricular (LV) volume and mass, most techniques have been relatively slow and required electrocardiogram (ECG) gating over many hea...

PURPOSE To compare standard of care nuclear SPECT imaging with cardiac magnetic resonance imaging (MRI) for emergency room (ER) patients with chest pain and intermediate probability for coronary artery disease. MATERIALS AND METHODS Thirty-one patients with chest pain, negative electrocardiogram (ECG), and negative cardiac enzymes who underwent cardiac single photon emission tomography (SPECT...
