摘要
目的探讨课题组自主开发的胎儿颅脑正中矢状面智能三维超声成像系统（SmartMSP）在显示胎儿颅脑正中矢状面及其在胎儿脑中线结构畸形诊断中的价值。方法对220例孕中期来我院常规超声系统筛查的孕妇进行SmartMSP检查，首先以胎儿双顶径平面为起始切面取一个三维容积，然后只需按一下“SmartMSP”按键，系统即可自动在C平面上显示胎儿颅脑正中矢状面。结果本组220例SmartMSP获取胎儿颅脑正中矢状面的成功率为94．5％（208／220）。200例正常胎儿中190例（95％）成功获取胎儿颅脑正中矢状面，10例（5％）失败。20例脑中线畸形胎儿中，18例（90％）成功获得具有诊断价值的胎儿颅脑正中矢状面，2例（10％）失败，所有异常胎儿均经胎儿或新生儿颅脑MRI检查证实。结论SmartMSP是一项自动显示胎儿颅脑正中矢状面的有效工具，可帮助超声医师更容易地获取胎儿颅脑正中矢状面，从而有望在未来成为筛查和诊断胎儿脑中线结构畸形的有效工具。
Objective To describe an intelligent three dimensional technique for automatic visualization of the fetal cranial mid-sagittal view to allow for the differential diagnosis of fetal midline anomalies. Methods Two hundred and twenty pregnant women with singleton pregnancies were imaged to display the mid-sagittal view of fetal head using a new 3D program （Smart MSP） developed by our team. Results The mid-sagittal view of the fetal head was successfully visualized in 191） normal cases （95%） and 18 abnormal cases （90%） by Smart MSP program. The total successful rate was 94.5% （208/220）. Conclusions Smart MSP is a novel and feasible method for the automatic visualization of fetal cranial mid- sagittal plane and may become a potential tool for routinely screening the fetal midline anomalies.
