A substantial boost in sensitivity (almost 10 5 ‐fold) achieved by combining remote‐detection MRI and parahydrogen‐induced polarization enabled microfluidic reactor imaging. Quantitative estimates of nuclear spin hyperpolarization, reaction product distribution, mass transport, and adsorption in the microfluidic reactors could thus be determined in situ. The reactors also serve as microfluidic nuclear spin polarizers.
