The application of a new technology, the early detection of lung disease in the People’s Republic could immensely improve in the years ahead
After five years of research, the scientists at Wuhan Insitute of Physics and Mathematics of the Chinese Academy of Sciences managed to make clearly recognizable images of human lungs, which represent the gas exchange within this. Gas exchange is a clear indication of the health of the institution. The photographs are the first recorded in China.
“Compared to traditional lung examination technologies such as computed tomography can pictures are generated by non-invasive and non-radioactive methods in the context of the new technology, the defects in gas exchange Visualize “, so the announcement of the nearby province of Hebei Institute.
At present, for the determination of lung diseases, various methods, such as X-ray, computed tomography or positron emission tomography applied, which examine the structure of the lung but can not provide information about their gas exchange.
“If abnormalities are detected in the structure of the lung is already damaged their function,” said Zhou Xin, head of research at Wuhan Institute. By means of the new technology can damage or abnormalities in the lung function is detected, which may give an indication of a lung disease in a very early stage.
made the recordings by the patient the isotope xenon-129 , a little reactive gas is inhaling, which can be monitored using magnetic resonance imaging. The areas of the lung, in which the gas has penetrated, are visible in the figure, whereas the parts that could not absorb it, remain black.
“On a few other institutes and universities abroad such as in the USA are operated similar research. However, they use helium, which is much rarer, “says Zhou and further explains that helium and xenon are the only two inert gases which are, due to their special physical properties for such investigations.
The central government with 30 million yuan (4.2 million euros) funded project, which was launched in 2010, comprises 60 scientists and physicians of Wuhan Insitute of Physics and Mathematics of the Chinese Academy of Sciences and the Zhongnan Hospital of Wuhan University.
According to the also participating in the project Doctor of Zhongnan Hospital, Wu Guangyao, are the images that can be achieved by means of new technology, much clearer and more accurate than CT scans.
“If the technology is applied clinically, they could help many people with lung diseases since the early is considerably improved.”
