magnetic resonance imaging (MRI) as a non-invasive diagnostic method has been evolving into an attractive alternative to methods which are associated with radiation exposure. This development now also starts to manifest itself in lung perfusion imaging. This was reported by Dr. Christian Fink and colleagues of the Radiology Division of the Deutsches Krebsforschungszentrum (German Cancer Research Center) in a recent issue of the journal Radiology*.
Diagnosis of numerous diseases of the lungs requires precise imaging of lung perfusion. The standard method used is called perfusion scintigraphy. It involves injecting a radioactive substance into a patient’s bloodstream and then making a scan of its distribution in the lungs. An equally precise and absolutely radiation-free method for evaluating lung perfusion now turns out to be magnetic resonance imaging (MRI, also called nuclear magnetic resonance (NMR) scan).
In a comparative study of 7 healthy probands and 20 patients with suspected lung cancer, the researchers compared magnetic resonance imaging to the standard method of perfusion scintigraphy. MRI showed a higher temporal and spatial resolution in lung perfusion imaging and provides the additional advantage of three-dimensional image data, which makes it easier to recognize blood circulation changes. Perfusion defects caused by tumors were recognized with high accuracy. In direct comparison with the standard method, MRI was found to be at least equally good.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
