Herlihy AH, Hajnal JV, Curati WL, et al. Reduction of CSF and blood flow artifacts on FLAIR images of the brain with k-space reordered by inversion time at each slice position (KRISP). WebThis is commonly known as the bounce-point artifact (originally named the "opposed magnetization artifact.") In IR imaging, tissue magnetization ... CSF has a longer T1 and recovers more slowly than brain. In magnitude-reconstructed IR only the absolute distance from zero of each tissue's recovery curve determines the displayed signal intensity.
