In this work, dynamic 3He and 1H images were acquired in a synchronised scan during inhalation providing regional gas flow with spatially and temporally registered lung anatomy motion. Lung ventilation is very fast (air reaches lung periphery within 1s) and demands fast sequences that can capture the rapid flow of 3He gas in lung airways. Compressed Sensing (CS) was used to assess the feasibility of accelerated synchronous 3He/1H acquisition.
