PURPOSE:To provide an MR(Magnetic Resonance) angiography method and apparatus therefor using two dimensional PC method in which imaging of the speed and the direction of blood circulation is possible. CONSTITUTION:After the magnetization intensity of the static region is decreased by the application of the polynomial pulse PP and the spoiler inclination SP through MT method, the prescribed slice is selected and excited by the application of the RF(Radio Frequency) pulse and the slice inclination S, two kinds of data are taken by the application of two different bipolar inclination pulse G1 and G2, and the image of blood circulation is acquired through the difference in the phase components of the two kinds of data. The projection dephase inclination is not applied. By this method, the direction of the circulation is seen even if the voxcel is long along the slice direction, and moreover, the error by remaining without going away can be decreased. |
