Feasibility of free breathing Lung MRI for Radiotherapy using non-Cartesian k-space acquisition schemes.

OBJECTIVE To test a free-breathing MRI protocol for anatomical and functional assessment during lung cancer radiotherapy by assessing two non-Cartesian acquisition schemes based on T1 weighted 3D gradient recall echo sequence: (i) stack-of stars (StarVIBE) and (ii) spiral (SpiralVIBE) trajectories. METHODS MR images on five healthy volunteers were… CONTINUE READING
