Abstract
To provide a technique with which a FLAIR image and a T1-weighted image can be acquired in a short scan time, a magnetic resonance imaging apparatus comprises: an RF driver unit 121 for driving an RF coil unit 103; a gradient coil driver unit 122 for driving a gradient coil unit 102; and a controller unit 124 connected to the RF coil driver unit 121 and gradient coil driver unit 122, for controlling them so that an imaging sequence ISc having a duration of 1TR for generating echoes from a body part being imaged is repetitively executed, where the imaging sequence ISc has a first sequence part SQ1 including an inversion pulse 11 and an FSE sequence 12, and a second sequence part SQ2 including an inversion pulse 21 and a GRE sequence 22.

A magnetic resonance imaging apparatus comprising:
- a first driver unit for driving an RF coil unit;
- a second driver unit for driving a gradient coil unit;
- and
- a controller unit for controlling said first driver unit and said second driver unit so that an imaging sequence having a duration of 1TR and being for generating echoes from a body part being imaged is repetitively executed, wherein
- said imaging sequence has a first sequence part for obtaining a FLAIR image, and a second sequence part executed after said first sequence part and being for obtaining a T1-weighted image, said first sequence part including:
- (1a) an α° pulse applied to said body part being imaged;
- and
- (1b) a spin-echo sequence for, after said α° pulse has been applied to said body part being imaged, generating spin echoes for obtaining a FLAIR image from said body part being imaged, and said second sequence part including:
- (2a) a β° pulse applied to said body part being imaged;
- and
- (2b) a gradient-echo sequence for, after said β° pulse has been applied to said body part being imaged, generating gradient echoes for obtaining a T1-weighted image from said body part being imaged.
A program for causing one or more processors to generate control signals for controlling a first driver unit for driving an RF coil unit and a second driver unit for driving a gradient coil unit so that a first sequence part for obtaining a FLAIR image, and a second sequence part executed after said first sequence part has been executed and being for obtaining a T1-weighted image are executed during 1TR, said first sequence part including:
- (1a) an α° pulse applied to a body part being imaged;
- and
- (1b) a spin-echo sequence for, after said α° pulse has been applied to said body part being imaged, generating spin echoes for obtaining a FLAIR image from said body part being imaged, and said second sequence part including:
- (2a) a β° pulse applied to said body part being imaged;
- and
- (2b) a gradient-echo sequence for, after said β° pulse has been applied to said body part being imaged, generating gradient echoes for obtaining a T1-weighted image from said body part being imaged.
