Table 3 Differences of IVIM parameters between different time points in locally advanced cervical cancer patients under concurrent chemo- radiotherapy (CCRT)

From: Evaluating early response of cervical cancer under concurrent chemo-radiotherapy by intravoxel incoherent motion MR imaging

Variables Time point 1 versus 2 Time point 1 versus 3 Time point 1 versus 4 Time point 2 versus 3 Time point 2 versus 4 Time point 3 versus 4
Diameter <0.001 < 0.001 < 0.001 < 0.001 < 0.001 < 0.001
D < 0.001 < 0.001 < 0.001 < 0.001 < 0.001 0.016
ADC < 0.001 < 0.001 < 0.001 < 0.001 < 0.001 0.879
f 0.002 < 0.001 0.005 0.408 0.337 0.047
D* 0.557 0.461 0.480 0.875 0.913 0.954
  1. Data are shown as p value from each comparison. Time point 1, before CCRT within one week; time point 2, at the end of the second week of CCRT; time point 3, at the end of the first month of CCRT; time point 4, immediately after CCRT within one week
  2. ADC apparent diffusion coefficient, D diffusion coefficient, f perfusion fraction, D* pseudo-diffusion coefficient
