Gas‐phase MRI phantom : Magnetic resonance imaging (MRI) in the gas phase was demonstrated using para‐hydrogen‐induced polarization. H 2 enriched in the para (antiparallel) spin state and propylene gas were flowed over solid‐supported Wilkinson's catalyst, and the product, propane gas, was collected in an NMR tube. Enhanced signal intensities were observed in the images of phantoms placed inside the NMR tube (see picture).
