Fig. 1
An example of a typical enhancement curve of a voxel of synovium during and post the administration of contrast agent. Three dynamic enhancement parameters are calculated from analysis of the enhancement curve; these variables (RER, REmax and RElate) are labelled on the curve. The x-axis is time in seconds. There are 22 s between each plotted point on the enhancement curve. The y-axis shows signal intensity, starting at zero
