Cardiac output (CO) assessment is important in treating patients with heart failure. Durable left ventricular assist devices (LVAD) provide essentially all CO. In currently used LVADs estimated device flow is generated by a computerized algorithm. However LVAD flow estimate may be inaccurate in tracking true cardiac output. We correlated LVAD ...

As a consequence of neural stimulation the blood oxygenation-level dependent (BOLD) contrast in gradient-echo echo-planar imaging (GE-EPI) based functional MRI (fMRI) leads to an increased MR signal in activated brain regions. Following this, a BOLD signal undershoot below baseline is generally observed with GE-EPI. The origin of this undershoot has ...
