| 摘要 |
According to an embodiment of the present invention, a perfusion-weighted imaging method comprises the following steps: acquiring first magnetic resonance information by applying a first gradient magnetic field to a target; acquiring second magnetic resonance information by applying a second gradient magnetic field to the target; and acquiring perfusion information from the difference between a first magnetic resonance signal and a second magnetic resonance signal. The first gradient magnetic field induces the transverse phase difference of spins of a moving proton included in the target. The second gradient compensates the transverse phase difference of spins of the moving proton included in the target. |
