NMR Microscope Allows Doctors to Focus on Diseased Soft Tissue

07.04.2004


Imagine what it was like to take a photograph of an object such as a tree, before the wide availablilty of zoom lenses. You would be able to make out the shape and the branches from a distance but you wouldn’t be able to see the smaller branches or leaves. Until recently, Doctors have been in a similar situation regarding NMR (nuclear magnetic resonance) imaging of organs and other features deep within the body. Thanks to a new NMR microscope developed by Oxford Researchers, Doctors will in future be able to focus in with a magnification factor of around x100 on ’hot spots’ or areas identified as a potentially life threatening soft tissue disease such as cancer or an aneurysm in order to make a more reliable diagnosis in a more comfortable way for the patient.



The imaging of very small features within the human body using NMR has long been a desirable objective, not only because the images provided using current methods of PET (Positron Emission Tomography) scanning are not detailed enough i.e. they do not allow images of organs or other features deep within the body to be created in enough detail, but also because they involve the use of unpleasant processes such as injecting opaque dyes and time restricted large dose levels of X-rays.

Researchers at Oxford University have developed a waveguide technology which permits the detailed examination of features located at its tip. The tapered pickup allows the collection of very localised signals whilst isolating them from surrounding objects resulting in the possibility of collecting very high resolution MRI data.


The simple, narrow, tapered pickup device basically works as a funnel for the electromagnetic fields used in NMR imaging, constricting and concentrating them down its bore such that the field strength at the tip of the device is significantly concentrated. In its simplest embodiments the concentration ratio determines the degree of field expansion produced. Waveguides with tips as narrow as 10 microns have been proposed, which would potentially magnify the field distribution presented at the tip by several hundred times.

"It is envisaged that this new technology is as significant to NMR imaging today as zoom lenses were to photography in the past. It will also help to make the process a much less daunting experience for the patient" stated Dr Robert Adams, a project manager for Isis Innovation Ltd the technology transfer company of Oxford University.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
