Claim Text:
1. A magnetic resonance imaging white matter hyperintensities region recognizing method, comprising: (a) receiving and storing a fluid attenuation inversion recovery (FLAIR) MRI image, a spin-lattice relaxation time weighted MRI image and a diffusion weighted MRI image; with respect to the fluid attenuation inversion recovery (FLAIR) MRI image, registering the spin-lattice relaxation time weighted MRI image to form a registered spin-lattice relaxation time weighted MRI image; determining a first region through the fluid attenuation inversion recovery (FLAIR) MRI image and the registered spin-lattice relaxation time weighted MRI image; (b) with respect to the fluid attenuation inversion recovery (FLAIR) MRI image, registering the diffusion weighted MRI image to form a registered diffusion weighted MRI image; determining a second region through the registered diffusion weighted MRI image; (c) when a continuous area of the first region overlaps the second region, removing the second region from the continuous area to form a remaining region; and (d) when the continuous area overlaps the second region and a ratio of the second region to the continuous area is larger than a predetermined value, removing the remaining region.
