We developed a method for automated quantification of myocardial perfusion from cardiac magnetic resonance (CMR) images. Our approach uses region-based and edge-based level set techniques for endocardial and epicardial border detection combined with non-rigid registration achieved by a 2D multi-scale cross-correlation and contour adaptation. This method was tested on 66 short-axis image sequences...
Although abnormal motion of the interventricular septum (IVS) caused by elevated right ventricular pressure in patients with pulmonary hypertension (PH) is easy to recognize visually, determination of the severity of PH relies on measurements of pulmonary arterial pressure (PAP). We hypothesized that quantitative 3D analysis of regional IVS curvature throughout the cardiac cycle could be used to differentiate...
Left ventricular (LV) remodeling is usually assessed using changes in LV volume, while disregarding regional changes that may occur independently of volume. We hypothesized that 3D analysis of regional endocardial curvature could provide useful information on localized remodeling. Cardiac magnetic resonance (CMR) images were acquired in 44 patients: 14 normal controls (NL), 15 with dilated cardiomyopathy...
Real-time 3D echocardiography (RT3DE), cardiac magnetic resonance (CMR) and cardiac computed tomography (CCT) can quantify right ventricular (RV) volume and overcome the limitations 2D echocardiography that stem from the unique geometry of the right ventricle. We tested a new technique for volumetric analysis of the right ventricle designed for RT3DE, CMR and CCT (TomTec) on images obtained in RV-shaped...
