A medical system including a memory storing machine executable instructions is disclosed. The medical system also includes a computational system. The execution of the machine executable instructions causes the computational system to receive k-space data descriptive of a region of interest of a subject. The k-space data are acquired using a magnetic resonance fingerprinting pulse sequence configured for encoding chemical shifts. The execution of the machine executable instructions also causes the computational system to receive fat peak weights descriptive of a magnetic resonance fat spectrum. The fat peak weights are matched to a pulse train of the magnetic resonance fingerprinting pulse sequence. The execution of the machine executable instructions also causes the computational system to reconstruct a quantitative magnetic resonance image from the k-space data and the fat peak weights.

Quantatative magnetic resonance imaging in the presence of fat

A magnetic resonance (MR) system configured to acquire MR data from a subject using a set of waveform and pulse sequence commands to prepare a first state of vibration of the one or more hardware elements and/or the subject. Preparing includes generating the vibration matching gradient inducing the first vibrations of the one or more hardware elements and/or the subject, while the net magnetization vector of the subject is aligned along the longitudinal axis of the main magnetic field. The MR system is configured to acquire the MR data by generating at least two spin manipulating gradients for manipulating phases of nuclear spins within the subject. A vibration matching gradient is used for matching with the first state of vibration with the second state of vibration.
