Study of multi-slice CT perfusion imaging on angiogenesis of VX_2 tumor in rabbits:before and after interventional therapy / 中华放射学杂志

0.05).Three days after interventional therapy,the values of BF,BV,MTT,PS,MVD and VEGF of VX_2 tumors in interventional group were (7.5?2.4)ml? 100g~(-1)?min~(-1),(1.20?0.23)ml/100g,(3.29?0.57)s,(4.0?1.5)ml?100g~(-1)?min~(-1), 16.0?2.4/HP and 0.215?0.008 respectively.Compared with the values of pre-interventional therapy and the control group,there were significant differences among them(P0.7,P0.05)but had a significant negative correlation with average A value of VEGF(r=-0.78,P
