Cardiac MRI and Fibrosis Quantification

Cardiac Electrophysiology Clinics, 2019
Left atrial fibrosis plays an important role in the pathophysiology of atrial fibrillation. Left atrial ablation is an effective and increasingly used strategy to restore and maintain sinus rhythm in patients with atrial fibrillation. Late gadolinium enhancement (LGE) MRI and custom image analysis software have been used to visualize and quantify ...

Cardiac MRI in the treatment of arrhythmias

Expert Review of Cardiovascular Therapy, 2013
Catheter-based ablation techniques are extensively used for the treatment of atrial and ventricular arrhythmias. Preprocedural cardiac MRI is valuable for the management of these patients due to its ability to provide high-resolution anatomic mapping and tissue characterization in the absence of ionizing radiation.

MRI of cardiac rhabdomyoma in the fetus

European Radiology, 2003
Primary cardiac tumors are rarely diagnosed in utero and are usually seen on prenatal echocardiography. Cardiac rhabdomyomata can be associated with tuberous sclerosis. Prenatal MRI can be performed to assess associated malformations. This case report illustrates the ability of fetal MRI to image cardiac rhabdomyata and compares it with prenatal and ...

Cardiac activation mapping by MRI

MAGMA Magnetic Resonance Materials in Physics, Biology, and Medicine, 1996
To establish cardiac MRI as a tool for noninvasive evaluation of activation patterns, 10 healthy volunteers were examined by cine segmented turboFLASH imaging sequences. Sequence modifications for low signal blood-pool appearance were applied, i.e., bilateral spatial saturation for segmented turboFLASH imaging.

Ultrasound-driven cardiac MRI

Physica Medica, 2020
One of the challenges of cardiac MR imaging is the compensation of respiratory motion, which causes the heart and the surrounding tissues to move. Commonly-used methods to overcome this effect, breath-holding and MR navigation, present shortcomings in terms of available acquisition time or need to periodically interrupt the acquisition, respectively ...

Cardiac MRI: technical basis

La radiologia medica, 2020
Cardiac magnetic resonance (CMR) imaging is an effective method for noninvasively imaging the heart which in the last two decades impressively enhanced spatial and temporal resolution and imaging speed, broadening its spectrum of applications in cardiovascular disease.

Advances in pediatric cardiac MRI

Current Opinion in Pediatrics, 2016
Purpose of review Spurred by numerous recent technological advances, cardiac MRI (CMR) is now the gold standard for anatomic evaluation, quantitative assessment of chamber size and function, flow quantification, and tissue characterization.

Cardiac MRI in Small Animals

2018
Cardiac magnetic resonance (MR) imaging of mice is a valuable tool for the precise in vivo diagnosis and prognosis of heart defects. This detailed protocol describes the method of cardiac MR imaging in mice step by step. A series of MR images captures the contractile function of the mouse heart and post-processing of the image data yields morphometric ...

Cardiac MRI in restrictive cardiomyopathy

Clinical Radiology, 2012
Restrictive cardiomyopathy (RCM) is a specific group of heart muscle disorders characterized by inadequate ventricular relaxation during diastole. This leads to diastolic dysfunction with relative preservation of systolic function. Although short axis systolic function is usually preserved in RCM, the long axis systolic function may be severely ...

Cardiac MRI in Rheumatic Disease

Rheumatic Disease Clinics of North America
Immune-mediated systemic inflammatory disorders present a latent threat for cardiovascular disease. Early involvement may be associated with constitutional symptoms, while clinical evidence of disease may manifest later in an insidious manner. Multimodality imaging is crucial to detect myocardial involvement, with transthoracic echocardiogram as a ...
