Table 3 DCE-MRI parameters in patients with different mrEMVI statuses

From: Association between high-resolution MRI-detected extramural vascular invasion and tumour microcirculation estimated by dynamic contrast-enhanced MRI in rectal cancer: preliminary results

  Total mrEMVI (−) mrEMVI (+) P
n = 72 (100%) n = 47 (65.3%) n = 25 (34.7%)
Ktrans (min−1) 0.231 ± 0.099 0.238 ± 0.104 0.217 ± 0.089 0.390a
kep (min−1) 0.859 ± 0.369 0.938 ± 0.364 0.710 ± 0.337 0.012a*
v e 0.307 ± 0.099 0.288 ± 0.094 0.344 ± 0.101 0.021a*
  1. DCE-MRI dynamic contrast-enhanced magnetic resonance imaging, mrEMVI magnetic resonance imaging-detected extramural vascular invasion, Ktrans volume transfer constant between blood plasma and extravascular extracellular space (EES), kep rate constant between EES and blood plasma, ve volume of EES per unit volume of tissue
  2. aindependent samples t-test, *indicates a significant difference
