Rings and Slings Revisited
Vascular rings and pulmonary artery slings are rare congenital anomalies that often present with symptoms of tracheal and esophageal compression. These can involve the aortic arch branches and pulmonary arteries,…
Coronary MR Angiography Revealed
Magnetic resonance (MR) imaging of the coronary arteries has been challenging, owing to the small size of the vessels and the complex motion caused by cardiac contraction and respiration. Free-breathing,…
Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia
Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a rare inherited cardiomyopathy characterized by fibrofatty replacement of the right ventricular myocardium and risk of sudden death from ventricular tachyarrhythmias. Cardiac magnetic resonance…
Prognostic Role of MR Imaging in Nonischemic Myocardial Disease
The role of cardiac magnetic resonance (MR) imaging as a prognostic tool in patients with ischemic heart disease is well established. However, an increasing body of data now demonstrates that…
MR Safety Issues Particular to Women
Because of its lack of ionizing radiation, MR imaging is increasingly used for patients with cardiovascular disease, including young women. However, the risks related to the MR environment need to…
MR Imaging Evaluation of Pericardial Constriction
Abnormal thickening or rigidity of the pericardium may compromise normal cardiac function. This condition is known as pericardial constriction, or constrictive pericarditis. Several imaging modalities are used to evaluate the…
MR of Multi-Organ Involvement in the Metabolic Syndrome
The metabolic syndrome (MetS) is characterized by ectopic lipid accumulation. Magnetic resonance (MR) imaging and spectroscopy can quantify ectopic lipid accumulation. Consequences of MetS can be evaluated with MR on…
Advances in MR Imaging Assessment of Adults with Congenital Heart Disease
Many novel cardiac MR sequences can be used for assessment of adult patients with congenital heart disease. Although most of these techniques are still primarily used in the research arena,…
T1 Mapping
T1 mapping, one form of tissue characterization performed with a parametric approach, has been gaining rapid popularity, as different sequences have been developed to integrate image acquisition into a clinical…
4D Flow MRI Applications for Aortic Disease
Aortic disease is routinely monitored with anatomic imaging, but until the recent advent of 3-directional phase contrast MRI (4D) flow, blood flow abnormalities have gone undetected. 4D flow measures aortic…
