A white matter hyperintensities region of magnetic resonance imaging recognizing method and system are disclosed herein, where the white matter hyperintensities region of magnetic resonance imaging recognizing method includes the following steps: receiving and storing a FLAIR MRI image, a spin-lattice relaxation time weighted MRI image, and a diffusion weighted MRI image registration fusion determining a white matter mask taking a intersection of the FLAIR MRI image and the white matter mask determining an region of possible white matter hyperintensities after normalizing the intersection image removing an region of cerebral infarct by using the diffusion weighted MRI, and then determining whether removing a remaining region to form a region of white matter hyperintensities in the FLAIR MRI image.一種磁共振造影之白質病變區域識別方法及系統在此揭露,其中白質病變區域識別方法包含以下步驟:接收與儲存液體衰減反轉恢復磁共振造影之影像、自旋晶格鬆弛時間加權磁共振造影之影像與擴散加權磁共振造影之影像;對位影像;合成影像;決定白質遮罩;交集液體衰減反轉恢復磁共振造影之影像與白質遮罩;標準化交集影像後決定可能白質病變區域;利用擴散加權磁共振造影之影像移除腦梗塞區域,再決定是否移除餘留區域以形成白質病變區域之液體衰減反轉恢復磁共振造影之影像。100‧‧‧磁共振造影之白質病變區域識別方法S102~S112‧‧‧步驟
