Magnetic resonance imaging method and apparatus

摘要

When performing imaging in synchronization with a biological movement of an examinee by using a pulse sequence applying a pre-saturation pulse, it is possible to reduce irregularities of echo signal intensity and artifact on the image generated by the irregularities. Especially, it is possible to prevent artifact attributed to blood in the ventricle when performing delay contrast imaging. For this, before measuring the echo signal, an IR pulse or the like for adjusting magnetization to a desired state is applied so as to suppress irregularities of the echo signal intensity and prevent artifact.
