Abstract:
In a magnetic resonance imaging procedure, multiple slices are initially spatially selectively excited in a first time interval by respective RF pulses followed by at least one RF refocusing pulse that causes one echo signal from each slice, with a time interval of two consecutive echo signals equal to the first time interval. A second RF refocusing pulse is emitted at a second time interval from the last echo signal that causes, one further echo signal per slice, with the time interval of two consecutive echo signals equal to the first time interval. At least one further RF refocusing pulse is emitted in a third time interval following the preceding RF refocusing pulse producing multiple temporally separated echo signals per refocusing pulse. The third time interval is selected so that the number of echo signals per RF refocusing pulse is twice the number of excited slices.
