Lung MRI is very challenging because of low proton density, cardiac and respiratory motion and susceptibility effects (T2*&[approx]1ms). Radial k-space sampling techniques provide very short echo and readout times. Additionally, they are motion insensitive due to central k-space averaging effects and thus being well suited for lung imaging. The implemented radial technique provides improved visibility of lung parenchyma and small vessels compared to conventional Cartesian gradient echo sampling. Furthermore it provides significantly reduced motion artifacts. Fast on-line reconstruction allows for immediate clinical diagnosis.
