Scientists have unveiled a new non-invasive technique for studying changes occurring on the surface of the brain. Researchers say the technique, which is based upon near-infrared spectroscopy, is easier to use and cheaper than other methods such as functional magnetic resonance imaging and positron emission tomography. The scanning method works by using near-infrared light to analyse blood flow and oxygen consumption in the brain. Researchers believe that the technique will be useful in a wide range of clinical situations both diagnostic and prognostic. Study leader Enrico Gratton, said of the technique: “It could also be used to monitor recovering stroke patients on a daily, or even hourly, basis – something that would be impractical to do with MRI..”
