OBJECTIVES To assess the prevalence and patterns of cardiac abnormalities as detected by cardiac magnetic resonance imaging (MRI) in systemic sclerosis (SSc). METHODS Fifty-two consecutive patients with SSc underwent cardiac MRI to determine morphological, functional, perfusion at rest and delayed enhancement abnormalities. RESULTS At least one abnormality on cardiac MRI was observed in 39/...

Imaging speed is a key factor in most cardiovascular applications of magnetic resonance imaging. Recently, simultaneous signal acquisition with multiple coils has received increasing attention as a means of enhancing scan speed in MRI. Based on this approach, the sensitivity encoding technique SENSE enables substantial scan time reduction by exploiting the inherent spatial encoding effect of re...

PURPOSE The purpose of this study was to compare long axis and short axis methods in cardiac magnetic resonance imaging (MRI), and echocardiography for the evaluation of left ventricular function and mass. MATERIALS AND METHODS The study included 15 patients with a history of myocardial infarction and 5 patients with normal ventricular function who were examined with cardiac MRI and echocardi...

The orientation of cardiac fibers affects the anatomical, mechanical, and electrophysiological properties of the heart. Although echocardiography is the most common imaging modality in clinical cardiac examination, it can only provide the cardiac geometry or motion information without cardiac fiber orientations. If the patient's cardiac fiber orientations can be mapped to his/her echocardiograp...

Amyloidosis refers to the accumulation of amyloid fibrils in different organs body that may result dysfunction organ systems. Cardiac amyloidosis (CA) is an cardiac tissue leads increase thickness and mass ventricular wall inducing progressive restrictive infiltrative cardiomyopathy. We present here a case 62-year-old male with complaints shortness breath on exertion, abdominal distention, leg ...

UNLABELLED In July 2009, the Medical Advisory Secretariat (MAS) began work on Non-Invasive Cardiac Imaging Technologies for the Diagnosis of Coronary Artery Disease (CAD), an evidence-based review of the literature surrounding different cardiac imaging modalities to ensure that appropriate technologies are accessed by patients suspected of having CAD. This project came about when the Health Ser...

Background MRI provides luminal, edema, & scar images which assist in the Electrophysiological (EP) treatment of ventricular and atrial arrhythmias]. Until a complete set of MR-compatible EP-devices is available, patients must be repeatedly moved between the MRI, where imaging and mapping occur, to the conventional EP suite, where puncture, navigation and Radio-Frequency Ablation occur. MRI-con...

This paper focuses on finding techniques that can be used in cardiac magnetic resonance images semiautomatic registration in a simple and fast way. The suggested technique depends on using parts of one image selected by the user to be matched with another image of the same patient in order to find control points or correspondences between those two images. The experiment focuses on three techni...

BACKGROUND Advanced heart failure treated with a left ventricular assist device is associated with a higher risk of right heart failure. Many advanced heart failures patients are treated with an ICD, a relative contraindication to MRI, prior to assist device placement. Given this limitation, left and right ventricular function for patients with an ICD is calculated using radionuclide angiograph...
