Abstract:
An MRI apparatus comprising:RF pulse transmitting means; gradient pulse applying means; MR signal receiving means; first MR data collecting means for, by controlling the aforesaid means, collecting first MR data from an echo focused by a first gradient echo sequence in which the intensity of a killer gradient applied to a slice axis is made equal to that of a slice selective gradient, the intensity of a slice rephasing gradient is made half or about half of that of the slice selective gradient, the intensity of a phase rewinding gradient is made half or about half of that of a phase encoding gradient, and the intensity of a frequency dephasing gradient is made double or about double of that of a readout gradient; and second MR data collecting means for collecting second MR data from an echo focused by a second gradient echo sequence in which the echo time is shifted by &dgr;t relative to said first gradient echo sequence.
