• Magnetic resonance angiography (MRA) is an excellent imaging modality for defining pulmonary venous anatomy before pulmonary vein isolation for treatment of atrial fibrillation. • Pulmonary vein stenosis, a possible…

• Optimal visualization of normal vascular anatomy with magnetic resonance angiography can be achieved with gadolinium-enhanced three-dimensional (3D) techniques, phased array surface coils, and parallel imaging. • Three-dimensional reconstruction techniques…

• Cardiovascular magnetic resonance (CMR) is the most accurate and comprehensive method available for assessment of left ventricular structure and function. It provides high spatial and temporal resolution and volumetric…

• Knowledge of the anatomy of the heart and in particular the three-dimensional (3D) relationships of the various normal structures is essential. • The heart lies at an oblique and…

• Cardiovascular magnetic resonance (CMR) first-pass perfusion has developed considerably in recent years, showing good results in single- and multicenter trials. • CMR first-pass perfusion provides high spatial resolution images…

• Myocardial strain is potentially a better measure of regional contractile function than motion of the endocardial border or tissue velocity, because strain directly quantifies the change in shape of…

• Cardiac magnetic resonance (CMR) can be used to detect and quantify the most common complications after repair of tetralogy of Fallot. CMR can accurately measure pulmonary regurgitant fraction (phase-contrast…

• Cardiac magnetic resonance (CMR) allows imaging of the entire RV without interference of ribs or lungs. • Because of high image quality and wide field-of-view, CMR imaging is the…

• Cardiovascular magnetic resonance (CMR) can identify valvular lesions, assess their severities, and determine the consequences of the valve lesion on left ventricular function. • CMR makes highly accurate and…
