The glomerular filtration rate (GFR) is a crucial
measurement for tailoring drug regimens and monitoring
patients with liver cirrhosis via renography. Dynamic
MRI presents sought contrast changes but also breathing
motion, which we correct via kidney detection. We have
developed a novel software offering an integrated
user-friendly tool to register dynamic kidney series,
select regions of interest, visualize time-varying
concentration, and calculate GFR values. With 98.69%
success rate in correction for motion of image frames,
our tool runs on different pltaforms and provides robust
registration while significantly reducing processing
time and giving accurate GFR values compared to an
existing software.
