摘要 |
With the objective of generating an imaging area including fluid with desired image quality at a subject and enhancing image quality, a first inversion recovery pulse is transmitted so as to invert spins in a second subject region which includes a first subject region used as the imaging area and is broader than the first subject region, before execution of a pulse sequence corresponding to an FSE method at every TR in an imaging sequence. After the execution of the pulse sequence corresponding to the FSE method, a second refocus pulse is transmitted so as to cause spins in a third subject region including the first subject region and wider than the first subject region to reconverge. A fast recovery pulse is transmitted to selectively recover spins in the first subject region. Thereafter, a second inversion recovery pulse is transmitted so as to invert the spins in the second subject region. |
