Embodiment Construction
[0036] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the following in conjunction with the attached Figure 1~4 Taking the hyperpolarized inert gas fast magnetic resonance imaging of rats under a 7T magnetic resonance imager as an example, the specific embodiment of the present invention will be described in detail.
[0037] A fast functional magnetic resonance imaging method for evaluating PM2.5-induced lung injury, comprising the following steps:
[0038] Step 1. Collect the hyperpolarized inert gas. The collected hyperpolarized inert gas is stored in a gaseous or solid state. If it is in a solid state, the solid hyperpolarized inert gas is sublimated into a gaseous state during use. hyperpolarized noble gases including hyperpolarized 3 He, hyperpolarized 83 Kr, hyperpolarized 129 Xe or Hyperpolarized 131 Xe.
[0039] Step 2. Carry out tracheal intubation on the anesthetized rat, connect th...
