A segmented radial Turbo Spin-Echo (rTSE) sequence was investigated towards its feasibility for high resolution lung imaging under free breathing conditions. No triggering techniques were involved to define the limits of the sequence itself. Unlike ultrafast singleshot techniques such as HASTE resolution is not intrinsically limited by the T2 signal decay while motion, especially of the beating heart, poses only a small problem in comparison with conventional Cartesian TSE. In addition, arbitrary T2 contrasts may be generated by postprocessing a single dataset allowing for the calculation of quantitative T2 maps.
