From: Liver functional assessment using time-associated change in the liver-to-spleen signal intensity ratio on enhanced magnetic resonance imaging: a retrospective study

Fig. 4

The definition of liver-to-spleen signal intensity ratio (LSR) increasing rate (LSRi). (a) Dynamic information on the LSR. Values of LSR calculated using four time points (1, 3, 10, and 15 min after injection) are selected. (b) Information from these four time points is plotted on a semi-logarithmic graph using a non-logarithmic scale for LSR (y axis) and a logarithmic scale for time after infection (x axis). (c) The approximate line of information from these four time points is created using the least-squares method, and the slope of the approximate line is defined as LSRi. The LSRi in this case is 0.3684
