Role of dynamic perfusion magnetic resonance imaging in patients with local advanced rectal cancer

Table 3 Differences in terms of perfusion parameters between responders and non-responders, in the tumor tissue, determines through a dynamic contrast enhanced magnetic resonance imaging study for staging rectal cancer (MR1)

DCE-MRI Parameters	Responders	Non-responders	P value
RAE (mean ± SD)	115 ± 21	85 ± 55	0.27
RVE (mean ± SD)	119 ± 21	120 ± 32	0.94
RLE (mean ± SD)	111 ± 14	117 ± 31	0.72
ME (mean ± SD)	1060 ± 325	1227 ± 371	0.52
TTP (mean ± SD)	196 ± 12	175 ± 70	0.51
AUC (mean ± SD)	203361 ± 14347	169033 ± 67738	0.28

DCE-MRI: Dynamic-contrast enhanced magnetic resonance imaging; RAE: Relative arterial enhancement; RVE: Relative venous enhancement; RLE: Relative late enhancement; ME: Maximum enhancement; TTP: Time to peak; AUC: Area under the curve.
