Figure 1. Transaxial section through map volumes from a patient with a glioblastoma multiforme (arrow head), acquired on day 0 (top and day 2 (bottom): (a) Time taken to achieve 90% enhancement (T90); (b) Maximal intensity change per time interval (MITR); (c) Volume transfer coefficient between plasma and the extravascular space (K^trans); and (d) the extravascular extracellular contrast distribution volume (v_e) maps. All parametric maps are colour rendered. Yellow represents high values, i.e. long T90, high MITR, high K^trans and large v_e. Dark-blue represents low values, i.e. short T90, low MITR, low K^trans and small v_e.
