Research on Magnetic Resonance Imaging of Lung Based on Hyperpolarized Gas129 Xe

Lung disease is one of the diseases that seriously threaten human health. For the assessment of many lung diseases in which early organic lesions are not readily apparent, radiographic imaging techniques are not suitable. They are frequently very harmful to early disease prevention and therapy and cause radiation damage to the patient. Hyperpolarized gas lung magnetic resonance imaging enables visualization and study of processes in living organisms and meets the need for functional imaging of the lung. The research is carried out from the principle of pulmonary MRI technology with hyperpolarized gas 129 Xe, hyperpolarized gas preparation device, pulmonary MRI RF coil, pulmonary MRI sequence and reconstruction algorithm of pulmonary MRI, and the reflections and suggestions are made for the above key technical issues.The Practice has shown that the lung MRI technique with hyperpolarized gas 129 Xe has better effect in improving the quality of lung MRI, which can overcome the defects and deficiencies of lung MRI and obtain clear images of the lung, facilitating the early diagnosis and prevention of lung diseases.
