Rigid‐body motion correction of the liver in image reconstruction for golden‐angle stack‐of‐stars DCE MRI

Respiratory motion can affect pharmacokinetic perfusion parameters quantified from liver dynamic contrast‐enhanced MRI. Image registration can be used to align dynamic images after reconstruction. However, intra‐image motion blur remains after alignment and can alter the shape of contrast‐agent uptake curves. We introduce a method to correct for inter‐ and intra‐image motion during image reconstruction.
