TABLE 2. CT Perfusion and Tumor Size Measurements Among Good Responders and Poor Responders at Baseline.

CT Perfusion Parameter Good
Responders
(n = 9)		 Poor
Responders
(n = 11)		 p a
Blood flow (mL/100 g/min) 72.7 ± 39.4 46.1 ± 57.5 0.2
Blood volume (mL/100 g) 5.4 ± 3.4 2.8 ± 2.4 0.05
MTT (s) 10.2 ± 4.4 9.8 ± 4.1 0.9
Permeability surface area product (mL/100 g/min) 15.7 ± 13.2 9.3 ± 9.2 0.2
Tumor size (cm) 5.9 ± 2 9.8 ± 5.2 0.05

Note—Except for p, data are mean ± SD. MTT = mean transit time. A p value of < 0.05 indicates a significant difference in the baseline and values between good responders and poor responders.
