In this work, 3D Flash examinations of the human lung were performed during free respiration using the DC signal for self-gating. Short echo times (TE) are required to provide sufficiently SNR because of the short T2* of the lung tissue. It is shown that the DC signal can be acquired after the actual imaging module still providing enough quality for respiratory gating and simultaneously providing very short echo times. The maxima and minima of the DC signal were used to define threshold values for data rejection and high resolution images were reconstructed retrospectively.
