In vivo tumor size measurement on T2-weighted images. (A-C) Representative axial T2-weighted images of one pancreatic tumor (dash line) in the control group at one week (A), three weeks (B) and five weeks (C) after initiation of treatment. (D-F) Representative axial T2-weighted images of one pancreatic tumor (dash line) in the treatment group at one week (D), three weeks (E) and five weeks (F) after initiation of treatment. (G) Changes of tumor longest diameters for the treatment and control group at different therapeutic time points (error bars indicate SD). There were no significant differences in the longest diameters of the pancreatic tumors between the treatment and the control group one week (P = 0.097) and three weeks after initiation of treatment (P = 0.500). The longest diameters of the pancreatic tumors in the control group were significantly longer than those in the treatment group five weeks after initiation of treatment (P = 0.021). (H) Changes of tumor volumes in the treatment and the control group at different therapeutic time points (error bars indicate SD, *P < 0.05). There were no significant differences in tumor volumes between the treatment and the control group one week after initiation of treatment (P = 0.076). Tumor volumes in the control group were significantly larger than those in the treatment group three weeks (P = 0.004) and five weeks after initiation of treatment (P = 0.001).
