    • In a method for determining the ventilation of a lung of an object under examination by magnetic resonance imaging, at least two first lung-representing image data sets are acquired at different intervals of the breathing phase. The density change of the lung tissue is automatically determined from the signal difference between the image signals of the first image data sets in at least one corresponding region of the first lung-representing image data set. The lung or the thorax volume is automatically determined using at least two of the first image data sets, or using at least an additional second lung-representing image data set in a breathing phase that corresponds with the breathing phase of a first image data set. The localized, quantitative ventilation of the lung is automatically calculated depending on the density change of the lung tissue and the change of the lung or thorax volume.
    • 在通过磁共振成像确定检查对象的肺的通气的方法中,在呼吸阶段的不同间隔获取至少两个第一肺代表图像数据集。 从第一肺代表图像数据组的至少一个对应区域中的第一图像数据组的图像信号之间的信号差自动确定肺组织的密度变化。 使用至少两个第一图像数据集或使用与第一图像数据集的呼吸相位对应的呼吸阶段中的至少另外的第二肺代表图像数据来自动确定肺或胸部体积。 根据肺组织的密度变化和肺或胸部体积的变化,自动计算肺的局部定量通气。
