To determine the accuracy of 4D sonography in the assessment of embryonic and early fetal motor activity in the first trimester of normal pregnancy, in comparison to the 2D sonography.
Fifty pregnant women between 6-14 weeks of gestation with singleton pregnancy were assigned for the investigation. Two dimensional and four dimensional recordings were displayed on the screen and recorded on the videotape during the 15 minutes observation period.
General body, head and limb movements recorded by 2D sonography were notable by 4D technique in the same gestational age. These movements were presented collectively with maximum, minimum, and median frequencies during 15 minutes observation period. Spearman rank order correlation reached statistical significance (P<0.05) between the frequencies of all observed movement patterns assessed by two different techniques. Several movement patterns, such as sideway bending, hiccup, breathing movements, mouth opening and facial movements could be observed only by 2D sonographic technique in this period of gestation.
Presently, both 2D and 4D methods are required for the assessment of early fetal motor development and motor behavior. It is reasonable to expect that such technological improvement may provide some new information about the intrauterine motor activity and facilitate the prenatal detection of some neurological disorders.
与二维超声检查相比，确定四维超声在评估正常妊娠早期胚胎和胎儿早期运动活动方面的准确性。
选取50例妊娠6 - 14周的单胎孕妇进行研究。在15分钟的观察期内，将二维和四维记录显示在屏幕上并录制到录像带上。
在相同孕周下，二维超声记录的全身、头部和肢体运动通过四维技术也很明显。在15分钟观察期内，这些运动以最大、最小和中位数频率共同呈现。两种不同技术评估的所有观察到的运动模式频率之间的斯皮尔曼等级相关达到统计学意义（P<0.05）。在此孕周期间，一些运动模式，如侧弯、打嗝、呼吸运动、张嘴和面部运动，只能通过二维超声技术观察到。
目前，评估早期胎儿运动发育和运动行为需要二维和四维方法。可以合理预期，这种技术改进可能会提供一些关于宫内运动活动的新信息，并有助于产前检测某些神经系统疾病。
