Peripheral arterial disease (PAD) can cause pain on walking and ischaemia resulting in pain when resting, ulceration and gangrene.
One in five people over the age of 65 is thought to have PAD. Risk factors for PAD include smoking, hypertension and diabetes. It is vital that the severity of the disease is accurately assessed as the best choice of treatment depends on how advanced the disease is.
Contrast angiography, the reference standard diagnostic test, is associated with adverse events related to arterial puncture, ionising radiation, and the injection of contrast agents needed to produce the images. Other imaging tests are available and include ultrasound, magnetic resonance and computed tomography (CT) angiography scans.
This systematic review assessed the research literature on the diagnostic accuracy of these different imaging techniques. When comparing the different tests, the review found that magnetic resonance angiography had the best overall diagnostic accuracy, and is generally preferred by patients over conventional contrast angiography.
However, it was not possible to compare the tests based on which gave patients the best outcomes as there was too little research available that measured this aspect.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
