Magnetic resonance imaging (MRI) of the heart and lungs is a valuable diagnostic tool in the medical industry, but the detailed images it produces are often marred by artefacts (unwanted signals) created by the motion of cardiac and respiratory cycles.
A team of inventors at Oxford University has now developed a method of suppressing MRI artefacts to a negligible level. This has potential to allow more precise conclusions to be made from a small number of experimental trials, with obvious potential within the pharmaceutical industry, both to accelerate research work and to improve the robustness and quality of screening data upon which key project decisions can be made.
Cardiac and thoracic MRI of small animals, such as mice, requires high spatial resolution in order to resolve fine detail. However, MRI is extremely sensitive to motion from the cardiac and respiratory cycles, which cause severe image artefacts. To reduce these artefacts, synchronisation (gating) to these physiological cycles is required.

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
