    Over 3.5 million cardiac catheterisations are performed in Europe each year. A study jointly conducted by radiologists and cardiologists at Charité – Universitätsmedizin Berlin and published in today’s issue of The BMJ compares computed tomography (CT) with cardiac catheterisation in patients with atypical chest pain and suspected coronary artery disease (CAD). We talked about the study results with Professor Marc Dewey, the principal investigator of the study.

  • Fraunhofer Institutes develop non-destructive quality test for hybrid cast components

    Lightweight design is increasingly applying trend-setting hybrid structures made of fiber composite materials and lightweight metal alloys, combining the advantages of both types of materials in hybrid construction techniques. In the current state of the art, the joints are bonded or riveted. In recent years at Fraunhofer IFAM, a new type of joining technology has been developed for various types of hybrid joints in high pressure die casting. In comparison with conventional joining techniques, the cast parts have advantages in package size, lower weight, and galvanic isolation.

  • Increased Usability and Precision in Vascular Imaging

    Researchers at the University of Zurich have developed a new X-ray contrast agent. The contrast agent is easier to use and distributes into all blood vessels more reliably, increasing the precision of vascular imaging. This reduces the number of animals required in research experiments. 
    Various diseases in humans and animals – such as tumors, strokes or chronic kidney disease – damage the blood vessels. Capillaries, the smallest blood vessels in the body, are particularly affected. The large surface area of the capillary network enables oxygen to be exchanged between the blood and the surrounding tissue, such as the muscles when we exercise or the brain when we think.

  • Operating in the operating theatre of the future

    Inselspital is the first hospital in Switzerland to have a highly modern surgical area that can be used in an interdisciplinary way by all surgical specialties. Modern imaging technologies inside the operating theatre allow for quality checks during complicated operations.

    Beginning in the middle of February, 2017, in the Intensive Treatment, Emergency and Operation Centre (IEO) at Inselspital, Bern University Hospital, all operative specialities will have three new operation theatres available that have integrated computer tomography (CT) and magnetic resonance imaging (MRI). Together with the hybrid operating theatre, which allows for intra-operative angiography, they create an operating area that is one of a kind in Switzerland.

  • Virtual Reality in Medicine: New Opportunities for Diagnostics and Surgical Planning

    Before an operation, surgeons have to obtain the most precise image possible of the anatomical structures of the part of the body undergoing surgery. University of Basel researchers have now developed a technology that uses computed tomography data to generate a three-dimensional image in real time for use in a virtual environment. The planning of a surgical procedure is an essential part of successful treatment. To determine how best to carry out procedures and where to make an incision, surgeons need to obtain as realistic an image as possible of anatomical structures such as bones, blood vessels, and tissues.
