[Real-time flow--determination of inferior vena cava on 2 different levels using RACE pulse sequence in MRI. Assessment of the total hepatic vein flow volume as an indirect parameter of liver perfusion].
A new and simple parameter for quantitative evaluation of liver perfusion is outlined: post-sinusoidal quantitative measurement of the entire liver venous flow: This is a result of the differences in evaluated flow volumes at two different levels in the inferior V. cava. The first level ist the height of diaphragm, and the second is situated just cranial of the renal vessels. Normal values obtained from a group of healthy volunteers are presented. A gradient-echo pulse sequence called RACE, enabling flow measurements in real-time, is outlined.
