摘要：

PROBLEM TO BE SOLVED: To provide an MRI apparatus which can obtain a T1 emphasis image in which T1 contrast and SNR per unit time are raised and image resolving power per unit time is raised in a tissue imaging method having an almost single T1 value like a TOF-MRA method and an ASL method.

SOLUTION: The MRI apparatus performs a pulse sequence including an inverting pulse or a saturation pulse impressed to a subject, two or more flip pulses impressed in the process of recovering the spin of the subject by T1 on this pulse, and a gradient magnetic field pulse for collecting echo signals which are generated in response to each of these flip pulses. This MRI apparatus has a collecting placement means which collects the echo signals and arrange them in k space, a correction means which corrects the intensity transition of the echo signals arranged in the k space, and a formation means which forms MR images from the echo signals corrected by this correction means.
