Figure 3.

Graphs showing the median parameter estimates and the corresponding median absolute deviation for each patient separately at visit 1, visit 2 and the post-RT visit. A steep decrease in ADC post-RT (a, single black arrow) corresponds to a small change in T2* across visits (b, single black arrow) for a mass with 40% viable tumour, 30% necrosis and high fat content. A steep early T2* decrease corresponds to a mass showing residual viable tumour and fibrosis (b, double black arrow). A steep reduction of (Gd) post-RT (c, single red arrow) corresponds to a mass with a reported prominent capillary vasculature. The same pattern was not observed in IAUGC60 which increased between these two visits (d, single red arrow). Number of patients considered in each graph: ADC (n_resp = 6, n_nresp = 4), T2* (n_resp = 6, n_nresp = 4), (Gd)/IAUGC60 (n_resp = 6, n_nresp = 3, one non-responder did not receive contrast agent), Ktrans (n_resp = 5, n_nresp = 3, baseline Ktrans was considered non-reliable for one responder and therefore the patient was excluded from the graph, one non-responder did not receive contrast agent), volume (n_resp = 6, n_nresp = 4). ADC, apparent diffusion coefficient.
