Stakeholder-developed interventions are needed to support pediatric intensive care unit (PICU) communication and decision-making. Few publications delineate methods and outcomes of stakeholder engagement in research. We describe the process and impact of stakeholder engagement on developing a PICU communication and decision-making support intervention. We also describe the resultant interventio...

Introduction The distribution of viable and infarcted myocardium is typically visualized using inversion recovery (IR) late gadolinium enhancement (1) or phase-sensitive inversion recovery (PSIR) sequences (2). Transitioning PSIR from breath-hold 2D to respiratory navigator-gated 3D imaging promises higher SNR and CNR, and whole heart coverage (3,4). However, the optimal method for motion compe...

BACKGROUND Patients who had received surgical services at Bellin Hospital reported anxiety with the surgical flow. This study tested the hypothesis that the introduction of a surgical navigator, someone who guided the patient and their accompanying others throughout the surgical process, would improve patient satisfaction. METHODS Ambulatory surgical patients were randomized to control and st...

Navigator gating techniques can effectively reduce motion effects in MRI by accepting data only when the object is in a small range of positions at the cost of significantly prolonging scan time. A simultaneous multiple volume (SMV) algorithm is reported here that can substantially increase the scan efficiency while maintaining the effectiveness of motion suppression. This is achieved by acquir...

R. G. Nunes, P. Jezzard, H. Johansen-Berg, T. E. Behrens, S. Clare FMRIB Centre, University of Oxford, Oxford, Oxfordshire, United Kingdom Synopsis: Interleaved Echo Planar Imaging (IEPI) can be used to produce high-resolution Diffusion-Weighted Images (DWI). However, DW makes the images particularly sensitive to patient motion, resulting in severe artefacts. These problems can be overcome by a...

This paper proposes a novel concept of intelligent navigator that can give the driver timely advice on safe and efficient driving. From both the current traffic condition obtained from visual data and the driver’s goal and preference in driving, it autonomously generates advice and give it to the driver. Not only operational level advice, such as emergency braking due to an abrupt deceleration ...

In this paper, an alternative training approach to the EEM-based training method is presented and a fuzzy reactive navigation architecture is described. The new training method is 270 times faster in learning speed; and is only 4% of the learning cost of the EEM method. It also has very reliable convergence of learning; very high number of learned rules (98.8%); and high adaptability. Using the...

Patients in vulnerable population groups suffer disproportionately from cancer. The elimination of cancer disparities is critically important for lessening the burden of cancer. Patient navigator programs have been shown to improve clinical outcomes. Among its provisions relevant to disparities in cancer care, The Patient Protection and Affordability Care Act authorizes continued funding of pat...

Background Real-time interactive (RTI) MRI parameter manipulation during the scan [1] may potentially address challenges imposed by respiratory motion during a free-breathing cardiovascular magnetic resonance (CMR) acquisition. In this study, we propose an operator-guided processing that allows manipulation of navigator gating parameters in real-time. This approach was evaluated in healthy volu...

Figure 3 (right) – Comparison of ky-onlyand ky-kz-reordered scans with 100% data acceptance and with a 4mm navigator window. Figure 1 (above) – Diagram illustrating the radial reordering process. Vertical axis is ky, horizontal axis is kz and color represents calculated radius in the top part of the figure. The bottom part of the figure shows the navigator signal and the respiratory gating wind...
