An inversion recovery true fast imaging with steady precession (FISP) pulse
sequence was developed to carry out fast imaging of the lungs at 0.2 T. Us
ing this sequence, oxygen-enhanced magnetic resonance (MR) lung imaging was
performed on healthy volunteers. The lungs showed signal enhancement (11.7
% +/- 3.8%) when breathing 100% oxygen. Using inversion recovery, true FISP
at low field may prove promising for MR lung imaging. (C) 2001 Wiley-Liss,
