What’s the best way to assess lower limb peripheral arterial disease?

14.06.2007
Contrast enhanced magnetic resonance angiography has better overall diagnostic accuracy than other imaging techniques, suggests a new systematic review published ahead of print in the BMJ.

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.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
