Abstract

Images of the kidneys using dynamic contrast-enhanced magnetic resonance renography (DCE-MRR) con-tains unwanted complex organ motion due to respiration. This gives rise to motion artefacts that hinder the clinical assessment of kidney function. However, due to the rapid change in contrast agent within the DCE-MR image sequence, commonly used intensity-based image registration techniques are likely to fail. While semi-automated approaches involving human experts are a possible alternative, they pose signi´Čücant drawbacks including inter-observer variability, and the bottleneck introduced through manual
