Abstract: 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.

Abstract: 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.

Abstract: Disclosed herein is a medical system comprising a memory storing machine executable instructions. The medical system further comprises 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, wherein the k-space data is acquired using a magnetic resonance fingerprinting pulse sequence configured for encoding chemical shifts; receive fat peak weights descriptive of a magnetic resonance fat spectrum, wherein the fat peak weights are matched to a pulse train of the magnetic resonance fingerprinting pulse sequence; and reconstruct a quantitative magnetic resonance image from the k-space data and the fat peak weighs.

Abstract: The invention relates to a magnetic resonance system (100) configured for acquiring magnetic resonance data from a GC subject (118). Execution of the machine executable instructions (140) stored in a memory (134) causes a processor (130) to control the magnetic resonance system (100) using a set of waveform and pulse sequence commands (142, 152) to prepare a first state of vibration (211) of the one or more hardware elements and/or the subject (118). The preparing comprises generating the vibration matching gradient (200) inducing the first vibrations (210) of the one or more hardware elements and/or the subject (118), while the net magnetization vector of the subject (118) is aligned along the longitudinal axis of the main magnetic field. The magnetic resonance system (100) is further controlled to acquire the magnetic resonance data (144, 154) according to a magnetic resonance protocol.
