Automatic 2D registration of renal perfusion image sequences by mutual information and adaptive prediction.

Unlabelled: The objective of this study was to develop an automatic image registration technique capable of compensating for kidney motion in renal perfusion MRI, to assess the effect of renal artery stenosis on the kidney parenchyma.

Materials And Methods: Images from 20 patients scheduled for a renal perfusion study were acquired using a 1.5 T scanner.
