The invention relates to a method to acquire magnetic resonance image data, an image data acquiring unit, a magnetic resonance apparatus and a computer program product. For effectively detecting optimized magnetic resonance sequences, the method to acquire magnetic resonance image data is provided, comprising the steps that: an examination subject is positioned in a magnetic resonance apparatus, and sequence parameters of a magnetic resonance sequence are established; first control commands of the magnetic resonance sequence are generated using the established sequence parameters; the first control commands are optimized so as to generate an optimized magnetic resonance sequence, the optimization of the first control commands including a conversion of the first control commands into optimized control commands; a test to review the optimized magnetic resonance sequence is implemented, the test including a comparison of the first control commands with the optimized control commands; the optimized magnetic resonance sequence is executed to acquire the magnetic resonance image data with the optimized control commands depending on the result of the test.
