目的　應(yīng)用三維彩色能量多普勒超聲成像（3D-CPA）評估妊娠13～41孕周乙型肝炎（乙肝）孕婦的肝臟灌注的價值。方法　選取2012年2月－2013年6月孕檢的13～41孕周孕婦117例，其中乙肝孕婦73例和健康孕婦44例。在孕婦肝右葉門靜脈分支附近進(jìn)行采樣，通過虛擬組織計算機輔助分析軟件（VOCAL）分析獲得血管化指數(shù)（VI）、血流指數(shù)（FI）、血管化血流指數(shù)（VFI）。比較乙肝孕婦與健康孕婦的肝臟灌注差異。結(jié)果　乙型肝炎病毒（HBV）-DNA病毒載量組和對照組之間由3D-CPA獲得的肝臟血管指數(shù)差異有統(tǒng)計學(xué)意義（P＜0.05），3個血管指數(shù)的臨界值分別為VI=8.760（P＜3×10?4）、FI=22.180（P＜6×10?7）、VFI=1.575（P＜3×10?5）。結(jié)論　應(yīng)用3D-CPA評估肝臟灌注可以分辨感染HBV的孕婦與健康孕婦，在一定程度上為臨床預(yù)防和治療孕婦感染HBV提供幫助。
