发明名称 MRI method and apparatus using independent gradient magnetic field spolier pulses
摘要 In fast imaging of a multi-echo method represented by a fast spin echo (FSE) method, a pulse sequence is arranged such that a basic condition relating to a CPMG method is satisfied and a spoiler gradient magnetic field pulse is independently applied immediately after a flop pulse. The spoiler gradient magnetic field pulse for suppressing an undesired signal is applied by a predetermined amount or more so as to prevent superimposition of other gradient magnetic field components such as a phase encoding component, a rewind component, etc., and to prevent a residual component of an FID signal caused by a certain RF pulse from being refocused by a subsequent RF pulse.
