Cardiac function by magnetic resonance imaging
International Journal of Cardiac Imaging, 1988Gated magnetic resonance imaging of the heart displays cardiac structures with excellent resolution. This ability should be useful for assessment of cardiac physiology where acquisition of systolic and diastolic images is required. In this study, left ventricular ejection fraction was determined in 50 patients from oblique long axis views of the left ...

Magnetic resonance imaging of cardiac sarcomas
Journal of Thoracic Imaging, 1989Two patients with cardiac sarcomas were evaluated with magnetic resonance imaging (MRI). In both cases, MRI provided more information regarding the extent of the tumor than computed tomography, two-dimensional echocardiography, or angiography.

Magnetic resonance imaging of cardiac amyloidosis
QJM, 2015A 65-year-old woman consulted our hospital after the detection of heart enlargement on chest radiography and high N-terminal pro-brain natriuretic peptide levels on blood tests by her primary physician. Low voltage was noted on electrocardiography at a medical health check 3 months previously.

Magnetic resonance imaging of cardiac hemangiopericytoma
Heart and Vessels, 1995We report a patient with hemangiopericytoma, a rare soft tissue sarcoma, involving the left ventricle. T1- and T2-weighted magnetic resonance imaging (MRI) revealed a high signal mass invading the left ventricular wall. A biopsied specimen obtained from the metastatic subcutaneous tumor in the right popliteal fossa showed pathologic findings consistent

Restoration of cardiac magnetic resonance images
[1990] Proceedings. Third Annual IEEE Symposium on Computer-Based Medical Systems, 2002Motion artifacts due to heart motion and blood flow within the heart chambers are a significant barrier to accurate interpretation of cardiac magnetic resonance images (MRI). The post-processing techniques of Wiener filtering, alternating projections onto convex sets (POCS), and mean field annealing (MFA) to remove these artifacts are studied.

Cardiac magnetic resonance imaging in children
Pediatric Radiology, 2015MRI is an important additional tool in the diagnostic work-up of children with congenital heart disease. This review aims to summarise the role MRI has in this patient population. Echocardiography remains the main diagnostic tool in congenital heart disease. In specific situations, MRI is used for anatomical imaging of congenital heart disease.

Interventional cardiac magnetic resonance imaging
Seminars in Roentgenology, 2003t v a s B AGNETIC RESONANCE imaging (MRI) has become the preferred routine imaging odality for many diagnostic questions. It offers uperior soft-tissue contrast, true cross-sectional or -dimensional coverage in arbitrary orientation, nd there are no known side effects. In recent ears, progress in both hardware and software aused a considerable boost of

From Signal to Image: Magnetic Resonance Imaging Physics for Cardiac Magnetic Resonance
Pediatric Cardiology, 2000Magnetic resonance imaging (MRI) is a powerful tool which enables the visualization of anatomy and the assessment of many physiological aspects of organ function. MRI and magnetic resonance angiography and magnetic resonance spectroscopy will play critical roles in cardiac applications during the next millennium.
