Abstract:
In a method and magnetic resonance (MR) apparatus for correction of artifacts in time-of-flight (TOF) MR angiography, MR signals are acquired in a target volume with the TOF MR angiography technique to generate multiple MR angiography images, pixels with background signal are identified in the angiography images by separation of these pixels from noise and vessel pixels, a signal profile of the pixels with background signal is determined across the target volume, and the MR signal of a predetermined set of pixels of the target volume is normalized with the signal profile of the pixels with background signal.
