Fusion of 3D-CMR-perfusion with 3D-MR-coronary angiography
Background The most relevant parameters for the assessment of coronary artery disease (CAD) are myocardial perfusion and the status of the coronary arteries. It has been shown that hybrid imaging strategies to acquire both parameters such as SPECT with CT-angiography provide an added value for clinical decision making in the treatment of CAD. However, SPECT and CT expose the patient to ionizing...
متن کامل3D-Rotational Phase-Contrast MR Angiography
Introduction For many applications of MRI angiography (MRA), high spatial resolution images obtained in reasonable scan times are required. For significantly decreasing the image acquisition time, projection reconstruction based approaches have been proposed, using highly undersampled two-dimensional projections [1,2]. These methods have e.g. been successfully applied to temporally resolved MRA...
متن کاملTime-resolved contrast-enhanced 3D MR angiography.
An MR angiographic technique, referred to as 3D TRICKS (3D time-resolved imaging of contrast kinetics) has been developed. This technique combines and extends to 3D imaging several previously published elements. These elements include an increased sampling rate for lower spatial frequencies, temporal interpolation of k-space views, and zero-filling in the slice-encoding dimension. When appropri...
متن کاملPulmonary MR Angiography in Swyer-James Syndrome
Aim: The aim of this study was to investigate the pulmonary magnetic resonance angiography (MRA) imaging findings in Swyer – James syndrome (SJS) as a alternative imaging modalities. Methods: Thirteen patients had posteroanterior inspiratory/expiratory chest X-ray films and pulmonary MRA with SJS (6 males, 7 females) were retrospectively studied. Gradient-echo pulmonary MRA was performed in all...
متن کاملFast isotropic volumetric coronary MR angiography using free-breathing 3D radial balanced FFE acquisition.
A shortcoming of current coronary MRA methods with thin-slab 3D acquisitions is the time-consuming examination necessitated by extensive scout scanning and precise slice planning. To improve ease of use and cover larger parts of the anatomy, it appears desirable to image the entire heart with high spatial resolution instead. For this purpose, an isotropic 3D-radial acquisition was employed in t...
