英文摘要 | Abstract Hyperpolarized (HP) xenon MR has been an important tool for quantifying the pulmonary structure and gaining functional information by measuring the dynamics of xenon in different lung components, e.g., gas exchange between gaseous xenon in the alveoli and dissolved xenon in tissue/plasma? and red blood cells. Chemical shift saturation recovery is a commonly used pulse sequence to measure the xenon dynamics in the lung globally. However, the effect of the dissolved xenon signal oscillation caused by the cardiac cycle on the physiological parameters of the lung is still unclear. In this study, both single-breathhold (SB) and multiple-breathhold (MB) measurements were used to evaluate these effects in rats, and the data acquired with the MB measurement, which did not have oscillations, served as a reference. The pulmonary physiological parameters were extracted using the model of xenon exchange. The results showed that the physiological parameters derived from SB and MB measurements were not significantly different. These findings have clarified a previously unknown issue and will further promote the design of faster real-time acquisition sequences to quantify structural and functional information about the lung. |
