On time-resolved contrast enhanced MRI, a cirrhotic
liver tends to enhance less and more slowly than the
normal liver. In addition, it is well known that the
ratio of arterial to portal blood supply for the liver
increases in cirrhosis. In previous approaches, a
separate 2D contrast enhanced exam was necessary to
sample the liver enhancement curve with high temporal
resolution, complicating the integration of this method
into clinical practice. We hypothesize that these
differences in liver perfusion between normal and
cirrhotic liver can be detected using a high frame rate
3D contrast enhanced MRI of the liver obtained with the
TRACER method.
