【摘要】 目的：应用高分辨率血流显像(high definition flow， HDF)技术对200例胎儿静脉系统进行显示，探讨HDF在胎儿静脉系统中应用的可行性。方法：采用HDF技术对200例正常胎儿肺静脉、静脉导管及下腔静脉进行显示，并与彩色多普勒显像进行对比。结果： HDF对1条肺静脉显示率为100%(200/200)，2条显示率为95%(190/200)，3条显示率为70%(140/200)，4条显示率为56%(112/200)。彩色多普勒对1条肺静脉的显示率99%(198/200)，2条显示率为85%(170/200)，3条显示率为40%(80/200)，4条显示率为21%(42/200)。HDF对静脉导管显示率为98%(196/200)，彩色多普勒对静脉导管显示率为95%(190/200)，HDF与彩色勒对3条，4条显示率比较，差异有统计学意义(P<0.05)。HDF对下腔静脉显示率为100%(200/200)，彩色多普勒对下腔静脉显示率98%(196/200)。结论：HDF技术可清晰显示胎儿静脉系统，对细小低速血流，如肺静脉的显示更有优势。

Application of High Definition Flow Technique in Normal Fetal Venous System/XU Jin.//Medical Innovation of China，2012，9(31)：066-067
【Abstract】 Objective：To explore the feasibility of high definition flow(HDF) in the application of normal fetal venous system.Method：Two hundred normal singleton pregnancies between 20 and 40 week gestation were examined by HDF and color Doppler flow imaging. Result：One pulmonary vein were displayed with HDF in 200 fetuses(100. 00%)， two pulmonary veins were displayed with HDF in 190 fetuses(95. 00%)， three pulmonary veins were displayed with HDF in140 fetuses(70. 00%)and four pulmonary veins were displayed with HDF at the same time in 112 fetuses (56%).One pulmonary vein were displayed with CDFI in 198 fetuses(99. 00%)， two pulmonary veins were displayed with CDFI in 170 fetuses(85. 00%)， three pulmonary veins were displayed with CDFI in 80 fetuses (40. 00%)and four pulmonary veins were displayed with CDFI at the same time in 42 fetuses (21%). Conclusion： HDF can demonstrate the number of pulmonary vein.
