肝动脉栓塞术的磁共振灌注成像的评价
【目的】 探讨MR灌注成像定量检测肝动脉栓塞前后肝脏血流动力学的改变及应用价值。【方法】对8头健康实验家猪行肝动脉栓塞术,分别于栓塞前及栓塞后3 d和1周行肝脏MR灌注扫描,计算肝脏各血流动力学参数,并行统计学分析。【结果】 (1)实验家猪肝动脉栓塞前及栓塞后3 d和1周的各项MR灌注测量肝脏血流参数中,HAP。PVP。THBF。PVI及DV的差异具有统计学意义(P = 0.001,0.002,0.000,0.000和0.008),MTT的差异无统计学意义(P = 0.17);(2)肝动脉栓塞后不同时间肝脏血流动力学参数变化特点:① 术后3 d实验家猪HAP较术前明显减低,PVI明显增加,差异...
