Abstract: In a spectroscopic magnetic resonance imaging method and apparatus, one or both of an SSFP-RF FID-like signal and an SSFP-RF echo-like signal are read out in one or two readout windows. The readout of this signal or these signals can take place with or without the presence of a magnetic field gradient.

Abstract: The invention relates to a heat exchanger (2), especially for use in a cooling circuit (1) of a vehicle, comprising at least one heat transfer network (3), whereby the heat transfer network (3) comprises at least one tubular device, and a cooling circuit (1) associated therewith. According to the invention, the tubular device has a characteristic hydraulic diameter which is smaller than or equal to 2.0 mm.

Abstract: In a spectroscopic imaging method for a magnetic resonance apparatus, an excitation radio-frequency pulse having a flip angle of approximately 90° is emitted, followed by transmission of a rephasing radio-frequency pulse having a flip angle of 180°, activation of a phase-coding gradient, and activation of a readout gradient and acquisition of a magnetic resonance signal. The following steps are then executed at least three times. A rephasing radio-frequency pulse having a flip angle of 180° and having a 90° phase offset in relation to a chronologically immediately preceding rephasing radio-frequency pulse is emitted, and the readout gradient is activated and a magnetic resonance signal is acquired.
