Diffusion-weighted MRI can diagnose ’mad cow’-related disease in humans before symptoms show

02.02.2005


Diffusion-weighted MRI is "extremely useful" in detecting Creutzfeldt-Jakob disease (CJD), a close cousin of "mad cow" disease, very early in its progression--even before the onset of characteristic clinical findings, according to a new study by researchers from Showa University Northern Yokohama Hospital in Japan.



For the study, researchers analyzed nine cases of CJD in which MRI of the brain was performed during early, intermediate and late stages of the disease. At the early stage, researchers were able to detect the disease using diffusion-weighted MRI in all cases.

Diffusion-weighted MRI follows the random motion of water molecules throughout the brain. According to Ryutarou Ukisu, MD, lead author of the study, diffusion-weighted MRI is useful for many conditions, and it is widely used for early detection of stroke-related conditions.


According to the study authors, early diagnosis of CJD is notoriously difficult and is often complicated by its frequent confusion with other causes of dementia, although its diagnosis is a critical one. "Although no cure for CJD exists, early detection of the disease may become more important when effective therapeutic measures are available. Also, since CJD is an infectious disease, the handling of tissue specimens and body fluids requires special care. Human-to-human infection has been reported, and early diagnosis definitely plays a positive role in its prevention of spread," said Dr. Ukisu.

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....
