Intervention to lower anxiety of 18F-FDG PET/CT patients by use of audiovisual imagery during the uptake phase before imaging.

Unlabelled: Many patients referred for PET suffer from anxiety, possibly affecting the workflow and patient experience. In addition, patient anxiety may affect image quality through uptake of (18)F-FDG in muscles or brown adipose tissue (BAT).This study investigated the effects of a nonpharmacologic intervention-the use of audiovisual imagery in the PET uptake room-on patient anxiety and false-positive uptake of (18)F-FDG (in muscles and BAT).

Artificial cilia for active micro-fluidic mixing.

In lab-on-chip devices, on which complete (bio-)chemical analysis laboratories are miniaturized and integrated, it is essential to manipulate fluids in sub-millimetre channels and sub-microlitre chambers. A special challenge in these small micro-fluidic systems is to create good mixing flows, since it is almost impossible to generate turbulence. We propose an active micro-fluidic mixing concept inspired by nature, namely by micro-organisms that swim through a liquid by oscillating microscopic hairs, cilia, that cover their surface.
