摘要:
An MR imaging method comprising detecting resonant signals from a portion including blood vessels by the three-dimensional imaging incorporating depthwise information, and performing subtraction, with respect to the signal data in each voxel in the complex number representation, between the image data obtained by adding the complex numbers in the projection direction and the image data obtained by adding the absolute values of the complex numbers in the projection direction, to extract the image of only the blood vessel.
