Sugar Lights-Up Cancer During MRI Scans

Researchers at UCL have discovered a method for detecting cancer by imaging the consumption of sugar with magnetic resonance imaging (MRI).

The technique –‘glucose chemical exchange saturation transfer’ (glucoCEST) - is based on the fact that tumours consume much more glucose than normal, healthy tissues in order to sustain their growth.

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.”

He continued: “In the future, patients could potentially be scanned in local hospitals, rather than being referred to specialist medical centres.”

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.”

The study is published in the journal Nature Medicine and trials are now underway to detect glucose in human cancers.
