摘要: A magnetic resonance imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry sets a pulse sequence to collect plural echo signals by application of a refocusing pulse more than once after application of an excitation pulse once, and collects data on plural slices that are parallel to each other by executing the pulse sequence more than once. The processing circuitry sets the pulse sequence such that a slice thickness for the refocusing pulse becomes larger than a slice thickness for the excitation pulse, and collects the data on the plural slices by executing the pulse sequence without consecutively collecting data on adjacent ones of the plural slices.

摘要: A magnetic resonance imaging method according to an embodiment is a method for implementing a multi-shot Fast Spin Echo method. The method includes acquiring, for a k-space divided into a plurality of segments with respect to a phase encode direction, one of the segments including a central region of the k-space with one shot, wherein, during the one-shot acquisition for the central region of the k-space, refocus pulses corresponding to a first time period among refocus pulses applied a plurality of times have a flip angle decreasing tendency, and refocus pulses corresponding to a second time period following the first time period among the refocus pulses applied the plurality of times have a flip angle maintaining or increasing tendency.
