Based on independent research and development of scientific instruments, the Zhou Xin Research Team of the State Key Laboratory of Spectroscopy and Atomic and Molecular Physics of the Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences, recently proposed a new rapid imaging technique for human lungs and achieved the fastest pulmonary magnetic resonance in the lungs. Imaging high-resolution dynamic sampling rate provides a new tool for the early diagnosis of major pulmonary diseases.
According to researcher Zhou Xin, pulmonary gas magnetic resonance imaging is an important clinical medical imaging technique with the advantage of no radioactivity. However, the majority of the lungs are hollow tissue, causing it to become a blind spot for conventional pulmonary gas magnetic resonance imaging.
It is difficult to accurately characterize the dynamic process of lung ventilation. Therefore, the development of new technologies for dynamic visualization of lung ventilation has become the focus of attention in the industry.
Based on the research team's independently developed hyperpolarizing human lung gas magnetic resonance imaging equipment, the team of Zhou Xin has achieved visual observation of the gas exchange in the lungs and “lights up” the lungs. Further studies have found that when the hyperpolarized gas continuously enters the human lungs, a gas inflow effect having a large influence on the image quality will be generated. This is an important factor that is difficult to accurately portray the dynamics of lung ventilation.
In order to develop rapid high-resolution human lung gas magnetic resonance imaging technology, the researchers designed a strategy based on variable-angle excitation, combined with low-rank, sparse and other dynamic image characteristics, to significantly increase the speed and quality of signal acquisition. Compared with the existing methods for dynamic imaging of lungs, this technique achieves both improved temporal resolution and spatial resolution of gas magnetic resonance imaging in human lungs, providing rapid and rapid breathing for rapid diagnosis of major pulmonary diseases.
