Perfusion in the Tissue Surrounding Pancreatic Cancer and the Patient’s Prognosis

Figure 1

Analysis of pancreatic perfusion image. We analyzed the CT image dataset (of which Panel (a) is an excerpt) to obtain Panel (b). Panels (a) and (b) are magnified by the same factor. Panel (b) is a perfusion image of pancreatic blood flow (BF). Pancreatic BF is indicated by the scale on the left. Colors shift from black to red with increasing BF. The pancreatic regions of interest (ROIs) in Panels (a) and (b) have the same size and location. Panel (c) shows time-density curves for peritumoral noncancer (PTT) and cancer (T) sites for Panels (a) and (b). Panels (d) and (e) show the relationship between pancreatic AUC_PTT or BF_PTT and survival days, respectively.
