The invention provides for a magnetic resonance imaging system () for acquiring magnetic resonance data () of a subject () within an imaging zone (), wherein the magnetic resonance imaging system comprises a memory storing a set of parameter ranges (). At least a portion of the parameter ranges are user configurable. Machine executable instructions cause a processor controlling the magnetic resonance imaging system to: receive () configuration commands () configured for setting adjustable image acquisition parameters () of a pulse sequence recipe; determine () if an out of range status exists by determining if any of the configuration commands are outside of the parameter range; provide () a warning signal () if the out of range status exists; receive () a scan status command () from a user interface (); acquire () the magnetic resonance data by controlling the magnetic resonance imaging system using the pulse sequence recipe and the configuration commands if the scan status indicates an acceptance of the out of range status; label () the magnetic resonance data with a quality indicator (); and write () the magnetic resonance data with the quality indicator to a computer readable storage medium.

Tracking of image quality in magnetic resonance imaging

A method of MR imaging of a body () of a patient reduces contrast blurring in PROPELLER imaging combined with multi-echo acquisitions. The method includes the steps of:

Propeller MR imaging with relaxation weightings varying between k-space blades and k-space data lines

A magnetic resonance examination system is disclosed comprising a field probe system to measure the magnetic field distribution of the main magnetic field and gradient magnetic field. The measurements are made in an earlier configuration and yield the resultant magnetic field due to gradient switching or external causes. From the measured resultant magnetic field the response relation is derived and stored in the memory. The response relation from the memory is available for compensating activation of the gradient fields or correction in reconstruction for the response relation in reconstruction. This compensation or correction can be carried-out in a current configuration. Thus is the current configuration to field probes are needed.
