2、IP及OP對(duì)乙肝肝硬化背景SHCC的檢出率并定量分析上述4個(gè)序列檢測(cè)SHCC的信號(hào)噪聲比(SNR)及對(duì)比噪聲比(CNR)。結(jié)果T：WI、DWI、IP及OP對(duì)乙肝肝硬化背景SHCC的檢出率差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0．05)。SNR：DWI>IP>OP>T2WI，各組間SNR差異均有統(tǒng)計(jì)學(xué)意義(P<0．05)；CNR：DWI>T，WI、IP、OP，DW1分別與TWI、IP、OP比較差異均有統(tǒng)計(jì)學(xué)意義(P<0．05)，T2WI、IP、OP3組間差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0．05)。結(jié)論DWI檢測(cè)乙肝肝硬化背景SHCC的SNR和CNR最高，顯著優(yōu)于TWI
