Tissue characterization of the myocardium: state of the art characterization by magnetic resonance and computed tomography imaging

Radiologic Clinics of North America
Puskar Pattanayak, David A Bleumke

Abstract

Late gadolinium enhancement (LGE) is a simple, robust, well-validated method for assessing scar in acute and chronic myocardial infarction. LGE is useful for distinguishing between ischemic and nonischemic cardiomyopathy. Specific LGE patterns are seen in nonischemic cardiomyopathy. Patient studies using T1 mapping have varied in study, design, and acquisition sequences. Despite the differences in technique, a clear pattern that has been seen is that in cardiac disease postcontrast T1 times are shorter. Extracellular volume fraction measured with cardiac computed tomography represents a new approach to the clinical assessment of diffuse myocardial fibrosis by evaluating the distribution of iodinated contrast.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
