متن کامل4D flow imaging with MRI.
Magnetic resonance imaging (MRI) has become an important tool for the clinical evaluation of patients with cardiovascular disease. Since its introduction in the late 1980s, 2-dimensional phase contrast MRI (2D PC-MRI) has become a routine part of standard-of-care cardiac MRI for the assessment of regional blood flow in the heart and great vessels. More recently, time-resolved PC-MRI with veloci...
متن کاملQuantification of left atrial flow velocity distribution in atrial fibrillation using 4D flow MRI
Background Atrial fibrillation (AF) is an arrhythmia characterized by irregular electrical activity in the left atrium (LA). Thromboembolism is the most serious complication of AF, usually manifesting as stroke or systemic embolism (1). This is thought to be linked to the increased risk of thrombus formation in the LA due to a decrease in blood velocity (stasis) or flow abnormalities. A better ...
متن کاملFlow sensitive 4D MRI at 1.5T and 3T
flow visualization for the same volunteer examined at 1.5T (left) and 3T (right). Top: Time-average 3D PC-MRA was calculated from the 4D data and displayed as gray shaded semi transparent iso-surface. Bottom: Two emitter plane (top right) were used to generate systolic 3D steam-lines by forward / backward tracing of the measured threedirectional velocity vector field. Flow quantification was pe...
متن کاملRemote CMR 4D Flow Quantification of Pulmonary Flow
Background 4D MR flow has shown to have advantages over standard cardiac magnetic resonance (CMR), offering both anatomical and functional information in just a single acquisition. Pulmonary stenosis and pulmonary regurgitation are common problems in follow-up of patients with congenital heart disease. In this study we tested flow quantification at the level of the pulmonary valve (forward and ...
