A simultaneous implementation method of 3D subtraction magnetic resonance (MR) arteriography, 3D subtraction MR venography, and color-coded 4D MR angiography through post-processing of image information of 4D MR angiography according to an embodiment of the present disclosure may reduce scan time required to individually obtain an MR arteriography and an MR venography. In addition, not only anatomical information of arteries but also more accurate anatomical information of veins and more detailed hemodynamic information may be obtained.

A learning method for generating a multiphase collateral image comprises the steps of: receiving inputs of an MRI image of a head part and a multiphase collateral image generated on the basis of the MRI image; generating a brain mask by using the MRI image; generating an MRI image and a multiphase collateral image which are masked by the brain mask; and learning the masked multiphase collateral image for the masked MRI image by using a learning network.
