Coronary artery imaging at 3T using a novel ECG gated SSFP-Dixon sequence and a motion insensitive view ordering scheme
Purpose: MR Coronary Artery Imaging (CAI) remains challenging due to the need for high spatial resolution as well as due to constraints imposed by physiological motion and the stringent requirements for fat and muscle suppression to visualize the arterial signal with good contrast. 3D ECG gated balanced steady state free precession (SSFP) imaging has shown great promise due to its high SNR, exc...
متن کاملCoronary artery disease diagnosis by analysis of ECG depolarization.
For both men and women, coronary artery disease (CAD) is the leading cause of death in industrialized countries. CAD often shows atypical patterns in women, which makes its diagnosis particularly challenging, and in many instances misleading. Accurate CAD diagnosis is essential to provide appropriate treatment and increase the chances of positive outcome. Traditional non-invasive techniques for...
متن کاملResidual motion compensation in ECG-gated interventional cardiac vasculature reconstruction.
Three-dimensional reconstruction of cardiac vasculature from angiographic C-arm CT (rotational angiography) data is a major challenge. Motion artefacts corrupt image quality, reducing usability for diagnosis and guidance. Many state-of-the-art approaches depend on retrospective ECG-gating of projection data for image reconstruction. A trade-off has to be made regarding the size of the ECG-gatin...
متن کاملQuantification of peri-aortic root fat from non-contrast ECG-gated cardiac computed tomography.
In this data, we present the details of the cross-sectional study from Mackay Memorial Hospital, Taipei, Taiwan that examined the relationship between three-dimensional (3D) peri-aortic root fat (PARF) volumes, cardiometabolic risk profiles, carotid artery morphology and remodeling. Our sample is composed of a total 1492 adults who underwent an annual cardiovascular risk survey in Taiwan. PARF ...
متن کاملECG-Gated Interventional Cardiac Reconstruction for Non-periodic Motion
The 3-D reconstruction of cardiac vasculature using C-arm CT is an active and challenging field of research. In interventional environments patients often do have arrhythmic heart signals or cannot hold breath during the complete data acquisition. This important group of patients cannot be reconstructed with current approaches that do strongly depend on a high degree of cardiac motion periodici...
