Parameter (mean value) Baseline before RT (n = 15) During RT 6 wk after RT (n = 12)
Week 2 (n = 15) Week 4 (n = 14) Week 6 (n = 11)
BF (mL/100 g/min) 16.9 (6.6) 25.7 (16.7) 46.0 (25.9) 36.0 (23.0) 32.7 (12.7)

Abbreviations: RT = radiotherapy; BF = blood flow; BV = blood volume; MTT = mean transit time; CP = capillary permeability. Data are presented as mean (SD). Capillary permeability was not recorded for 2 patients at Week 2 (n = 13) and 1 patient at Week 6 (n = 10).
