Abstract
First and second RF pulses are applied to a .sup.1 H and, simultaneously with or after the application of the second RF pulse, a third RF pulse is applied to the .sup.13 C magnetically coupled to the .sup.1 H, whereby there occurs a first polarization transfer from the spin of the .sup.1 H to the spin of the .sup.13 C. After the first polarization transfer, a fourth RF pulse is applied to the .sup.13 C. After the application of the fourth RF pulse, a fifth RF pulse is applied to the .sup.1 H together with a first slice gradient magnetic pulse. By doing so, those .sup.1 H spins in the first area are selectively excited, there occurs a second polarization transfer from the spin of the .sup.13 C to the spin of the .sup.1 H and those first MR signals are collected from those spins of the .sup.1 H in the first area experiencing the first and second polarization transfers. After the collection of a first MR signal, a sixth RF pulse is applied to the .sup.1 H together with a second slice gradient magnetic field pulse, whereby those .sup.1 H in a second area are selectively excited, there occurs a third polarization transfer from the spin of the .sup.13 C to the spin .sup.1 H and those second MR signals are collected from the spins of the .sup.1 H in the second areas experiencing the first and third polarization transfers.
