A method for acquiring magnetic resonance raw data with two contrasts in a single scan, said method comprising: - operating an MR data acquisition scanner, while an examination subject is situated therein in a basic magnetic field having a basic field direction, to execute a simultaneous multi-slice data acquisition sequence in which nuclear spins respectively in multiple slices of the examination subject are simultaneously excited by, in a single scan of the examination subject, radiating, from a radio-frequency radiator of said MR data acquisition scanner, a multi-band binomial RF pulse in said SMS data acquisition sequence; - generating said MB binomial RF pulse in said SMS data acquisition sequence by radiating a first subset of pulses that excite different nuclear spin species in a first slice among said multiple slices to a different extent so as to give the different nuclear spin species respectively different nuclear spin magnetizations in the transverse plane in said first slice with respect to said basic field direction that produce a first contrast based on the different magnetizations for the different spin species excited in the first slice when an image of said first slice is reconstructed, and a second subset of pulses that excite nuclear spins in a second slice among said multiple slices to a different extent so as to give the different nuclear spin species respectively different nuclear spin magnetizations in the transverse plane in said second slice with respect to said basic field direction that produce a second contrast based on the different magnetizations for the different spin species excited in the second slice when an image of said second slice is reconstructed, said first and second contrasts being different from each other; - in said SMS data acquisition sequence, acquiring raw MR data at least from said first and second slices after said simultaneous excitation of nuclear spins with said MB binomial RF pulse, and entering the acquired raw MR data from said at least first and second slices as k-space data into an electronic memory, organized as k-space; and - via a computer having access to said electronic memory, making the k-space data in said electronic memory available in electronic form, as a datafile. - operating an MR data acquisition scanner, while an examination subject is situated therein in a basic magnetic field having a basic field direction, to execute a simultaneous multi-slice data acquisition sequence in which nuclear spins respectively in multiple slices of the examination subject are simultaneously excited by, in a single scan of the examination subject, radiating, from a radio-frequency radiator of said MR data acquisition scanner, a multi-band binomial RF pulse in said SMS data acquisition sequence; - generating said MB binomial RF pulse in said SMS data acquisition sequence by radiating a first subset of pulses that excite different nuclear spin species in a first slice among said multiple slices to a different extent so as to give the different nuclear spin species respectively different nuclear spin magnetizations in the transverse plane in said first slice with respect to said basic field direction that produce a first contrast based on the different magnetizations for the different spin species excited in the first slice when an image of said first slice is reconstructed, and a second subset of pulses that excite nuclear spins in a second slice among said multiple slices to a different extent so as to give the different nuclear spin species respectively different nuclear spin magnetizations in the transverse plane in said second slice with respect to said basic field direction that produce a second contrast based on the different magnetizations for the different spin species excited in the second slice when an image of said second slice is reconstructed, said first and second contrasts being different from each other; - in said SMS data acquisition sequence, acquiring raw MR data at least from said first and second slices after said simultaneous excitation of nuclear spins with said MB binomial RF pulse, and entering the acquired raw MR data from said at least first and second slices as k-space data into an electronic memory, organized as k-space; and - via a computer having access to said electronic memory, making the k-space data in said electronic memory available in electronic form, as a datafile.
