Three-dimensional gadolinium-enhanced coronary magnetic resonance angiography: initial experience.
We present our initial experience on first-pass gadolinium-enhanced coronary artery magnetic resonance angiography (MRA). Three-dimensional segmented gradient-echo sequences were developed to image coronary arteries within a single breathhold during the injection of a double-dose contrast agent. Comparisons were made between a short TR of 2.7-msec (n = 5) and a long TR of 5.0-msec (n = 3) seque...
متن کاملGadolinium-enhanced three-dimensional magnetic resonance angiography of pulmonary and systemic venous anomalies.
OBJECTIVE The goal of this study was to evaluate the diagnostic value of gadolinium (Gd)-enhanced three-dimensional (3D) magnetic resonance angiography (MRA) in patients with congenital and acquired anomalies of the pulmonary and systemic veins. BACKGROUND Gadolinium-enhanced 3D MRA is a fast magnetic resonance imaging technique that has shown great promise in the evaluation of large and medi...
متن کاملDetection of coronary stenoses with contrast enhanced, three-dimensional free breathing coronary MR angiography using the gadolinium-based intravascular contrast agent gadocoletic acid (B-22956).
PURPOSE To determine the diagnostic value of the intravascular contrast agent gadocoletic acid (B-22956) in three-dimensional, free breathing coronary magnetic resonance angiography (MRA) for stenosis detection in patients with suspected or known coronary artery disease. METHODS Eighteen patients underwent three-dimensional, free breathing coronary MRA of the left and right coronary system be...
متن کاملContrast-Enhanced MR Angiography
Magnetic resonance angiography (MRA) is increasingly used to evaluate arterial and venous diseases. Although the resolution of MRA is not as high as that of conventional angiography, it is sufficient to evaluate pathologic conditions in the larger vascular structures of most parts of the body. It is especially useful in patients who cannot tolerate the risks of iodinated contrast agents or arte...
متن کاملThree-Dimensional Model-Based Stenosis Quantification of the Carotid Arteries from Contrast-Enhanced MR Angiography
A model-based technique for quantitative analysis of three-dimensional magnetic resonance angiography (MRA) is presented. The model consists of a deformable B-spline representation of the central vessel axis and the vessel wall. An efficient interaction mechanism to initialize the models in a three-dimensional setting is devised. Two novel image features are introduced in order to deform the ce...
