Abstract
The invention provides for a magnetic resonance imaging system () comprising a memory () for storing machine executable instructions () and pulse sequence commands (). The pulse sequence commands are configured for controlling the magnetic resonance imaging system according to a DCE Magnetic Resonance Imaging protocol. The magnetic resonance imaging system further comprises a user interface () and a processor () for controlling the magnetic resonance imaging system. Execution of the machine executable instructions causes the processor to: control () the magnetic resonance imaging system using the pulse sequence commands to acquire calibration magnetic resonance data () two or more times for varying flip angles; reconstruct () each acquisition of the calibration magnetic resonance data into a calibration image () to create a set of variable flip angle images (); calculate () a T1 mapping () using the set of variable flip angle images; calculate () a contrast agent calibration () for a predetermined magnetic resonance imaging contrast agent using at least partially the T1 mapping; calculate () an estimated calibration error () that is descriptive of an estimated error in the contrast agent calibration and/or the T1 mapping using a calibration accuracy model, wherein the calibration accuracy model is configured for calculating the estimated calibration error using the set of variable flip angle images; and display () a calibration warning message () on the user interface if the estimated calibration error is outside of a predetermined calibration error range.
