The new technique, called 'glucose chemical exchange saturation transfer' (glucoCEST), is based on the fact that tumours consume much more glucose (a type of sugar) than normal, healthy tissues in order to sustain their growth.
UCL scientists have developed a new technique for detecting the uptake of sugar in tumors, using magnetic resonance imaging.
The researchers found that sensitising an MRI scanner to glucose uptake caused tumours to appear as bright images on MRI scans of mice.Lead researcher Dr Simon Walker-Samuel, from the UCL Centre for Advanced Biomedical Imaging (CABI) said: "GlucoCEST uses radio waves to magnetically label glucose in the body. This can then be detected in tumours using conventional MRI techniques. The method uses an injection of normal sugar and could offer a cheap, safe alternative to existing methods for detecting tumours, which require the injection of radioactive material." Professor Mark Lythgoe, Director of CABI and a senior author on the study, said: "We can detect cancer using the same sugar content found in half a standard sized chocolate bar. Our research reveals a useful and cost-effective method for imaging cancers using MRI – a standard imaging technology available in many large hospitals."
According to UCL's Professor Xavier Golay, another senior author on the study: "Our cross-disciplinary research could allow vulnerable patient groups such as pregnant women and young children to be scanned more regularly, without the risks associated with a dose of radiation." Dr Walker-Samuel added: "We have developed a new state-of-the-art imaging technique to visualise and map the location of tumours that will hopefully enable us to assess the efficacy of novel cancer therapies."The work was supported by public and charitable funding from the National Institute for Health Research University College London Hospitals Biomedical Research Centre, Cancer Research UK, Engineering and Physical Sciences Research Council (EPSRC) and the British Heart Foundation (BHF).

About UCL (University College London)
Founded in 1826, UCL was the first English university established after Oxford and Cambridge, the first to admit students regardless of race, class, religion or gender and the first to provide systematic teaching of law, architecture and medicine.
We are among the world's top universities, as reflected by our performance in a range of international rankings and tables. According to the Thomson Scientific Citation Index, UCL is the second most highly cited European university and the 15th most highly cited in the world.
UCL has nearly 27,000 students from 150 countries and more than 9,000 employees, of whom one third are from outside the UK. The university is based in Bloomsbury in the heart of London, but also has two international campuses – UCL Australia and UCL Qatar. Our annual income is more than £800 million.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
