Abstract:
1. A magnetic resonance imaging system comprising: a rare gas polarizer apparatus for supplying a rare gas in a hyperpolarized state to a subject; and a magnetic resonance imaging apparatus for acquiring magnetic resonance information on said subject inhaling said rare gas, said magnetic resonance imaging system characterized in that: said rare gas polarizer apparatus comprises a mask section; said rare gas polarizer apparatus has supplying section for supplying said rare gas mixed with an inspired material to said mask section closed against the outer air covering the respiratory organs of said subject; said supplying section has a detection sensor for detecting said respiration; said magnetic resonance imaging apparatus has a control processing section for conducting said acquisition or optimization of parameters for said acquisition based on respiration information from said detection sensor; and said rare gas polarizer apparatus comprises a flowmeter configured to measure a flow rate of said rare gas.
