The object of this work is the optimisation of 2D- and 3D FLASH sequences for examinations of the human lung at 0.2 Tesla The relaxation times T1 and T2* were measured and appropriate sequence parameters were calculated. The optimised FLASH sequences provide a high SNR in lung parenchyma and simultaneously allows for the aquisition of an adequate number of images in one breath-hold. First examinations of cystic fibrosis showed a clear contrast between healthy and diseased tissue. Examinations of the human lung with FLASH sequences seem to be promising at low magnetic fields.
