The primary purpose of this study is to improve the quality of Magnetic Resonance Imaging in patients with heart arrhythmia. Investigators will recruit 105 patients with arrhythmia and 30 control volunteers over 3 years and will use two arrhythmia-tolerant imaging methods for diagnosis.
In the proposed research, investigators will extend conventional cardiac magnetic resonance methods to enable the creation of high-quality cine CMR images in the presence of multiple kinds of arrhythmia. Two arrhythmia-tolerant imaging methods will be adopted, which are particularly useful in arrhythmia: 1) 3D imaging, which is useful for many purposes, including "road mapping" of electrophysiology (EP) procedures, and 2) late gadolinium enhancement (LGE), which is useful for delineating abnormal myocardium, including fibrotic regions that can serve as sources of arrhythmias.

Cardiac 3D navigator-gated late gadolinium enhancement (LGE) imaging is important for assessment of left atrial fibrosis, but the image quality is often degraded due to arrhythmia.
The aim of this study was to investigate the diagnostic value of cardiac magnetic resonance (CMR)-derived strain parameters in patients with sarcoidosis, and to compare results to standard CMR markers...
This study sought to investigate the association between the extent, location, and pattern of late gadolinium enhancement (LGE) and outcome in a large dilated cardiomyopathy (DCM) cohort.
Assessing the extent of ischemic and reperfusion-associated myocardial injuries remains challenging with current magnetic resonance imaging (MRI) techniques. Our aim was to develop a tissue characteri...

Gadolinium. An element of the rare earth family of metals. It has the atomic symbol Gd, atomic number 64, and atomic weight 157.25. Its oxide is used in the control rods of some nuclear reactors.
A complex of gadolinium with a chelating agent, diethylenetriamine penta-acetic acid (DTPA see PENTETIC ACID), that is given to enhance the image in cranial and spinal MRIs. (From Martindale, The Extra Pharmacopoeia, 30th ed, p706)
