Background For quantitative volumetric assessments of cardiac function, 3D cine images depicting motion of the entire ventricle in a complete cardiac cycle are needed. However, due to limited acceleration capability, breathheld 3D cine MRI is not obtainable using conventional parallel imaging. Several kt-acceleration methods have demonstrated high-acceleration capability for dynamic MRI by expl...
Recent developments in MRI enable the acquisition of image sequences with high spatio-temporal resolution. Cardiac motion can be captured without gating and triggering. Image size and contrast relations differ from conventional cardiac MRI cine sequences requiring new adapted analysis methods. We suggest a novel segmentation approach utilizing contrast invariant polar scanning techniques. It ha...
Background New developments and expanding indications have lead to a significant increase in the number of pacemakers and loop recorders being implanted. Alongside this cardiac magnetic resonance imaging (CMRI) is increasing being utilised in the assessment of cardiac disease. In the UK, MRI conditional devices are often now being implanted as the device of choice by cardiologists as it is assu...
BACKGROUND AND PURPOSE The frequency and prognostic significance of neuroradiological findings after cardiac arrest are unknown. Using healthy volunteers as control subjects, we studied the magnetic resonance imaging (MRI) findings associated with cardiac arrest, adjusted for confounding factors. METHODS The presence of cerebral infarcts, leukoaraiosis, atrophy, and edema on ultra-low-field M...
