Mean values, standard deviations (SD) and confidence intervals (CI) of blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability surface (PS) values for metastatic and inflammatory nodes. The p values of the Mann-Whitney U test are reported in the table. The Mann-Whitney U test proved a statistically significant difference between blood flow values of metastatic and inflammatory nodes (p < 0.05). However, the tests did not prove that the differences between the other parameters are statistically significant.
