Preclinical MR lung imaging has been challenging due to lower tissue density compared to other organs. Current practice has been 2D spin-echo or gradient echo with relatively lower resolution. In this work we present an optimized high resolution 3D Multi Gradient Echo and demonstrate the results by comparing it with state of the art 2D Gradient echo.
