Abstract
In one encoding process of MRI, a pulse sequence by a multi-echo method is executed to acquire first and second MR signals of a predetermined slice. A pulse sequence with a shorter echo time is executed by exciting the slice, thus acquiring a third MR signal. In this case, when an echo time and a repetition time are changed, the first MR signal becomes a signal with an emphasized atomic nuclear density, the second MR signal becomes a signal with an emphasized transverse relaxation time T2, and the third MR signal becomes a signal with an emphasized longitudinal relaxation time T1.
