Patent ID: 10935617

Abstract:
The invention provides for a magnetic resonance imaging system (100) comprising a memory (134) for storing machine executable instructions (140) and pulse sequence commands (142). 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 (200) and a processor (130) for controlling the magnetic resonance imaging system. Execution of the machine executable instructions causes the processor to: control (500) the magnetic resonance imaging system using the pulse sequence commands to acquire calibration magnetic resonance data (144) two or more times for varying flip angles; reconstruct (502) each acquisition of the calibration magnetic resonance data into a calibration image (146) to create a set of variable flip angle images (148); calculate (504) a T1 mapping (150) using the set of variable flip angle images; calculate (506) a contrast agent calibration (152) for a predetermined magnetic resonance imaging contrast agent using at least partially the T1 mapping; calculate (508) an estimated calibration error (154) 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 (510) a calibration warning message (202) on the user interface if the estimated calibration error is outside of a predetermined calibration error range.
