Three-dimensional ultrasound examination was performed in 204 patients with a fetal malformation detected by conventional ultrasound. The patients were examined between 13 and 40 weeks of gestation. The ultrasound equipment used was a Combison 330 and a Combison 530 (Kretztechnik, Austria) with an abdominal Voluson sector transducer (3.5/5 MHz) (Kretztechnik, Austria). This ultrasound system can provide a high-quality three-dimensional surface or translucency image of fetal structures similar to that of a photograph or an X-ray image within seconds without an additional expensive work-station. Of the 204 patients examined with three-dimensional ultrasound, this technique proved advantageous in demonstrating fetal defects in 62% (127/204). In 36% (73/204), the three-dimensional technique gave the same information and in four fetuses with a cardiac malformation (2%), the three-dimensional technique was disadvantageous, due to movement artefacts during data acquisition. The technical advantages and problems of this three-dimensional technique are demonstrated.
对204例经传统超声检查发现有胎儿畸形的患者进行了三维超声检查。这些患者在妊娠13至40周期间接受检查。使用的超声设备是一台Combison 330和一台Combison 530（奥地利Kretztechnik公司），配有腹部容积探头（3.5/5兆赫）（奥地利Kretztechnik公司）。该超声系统能够在数秒内提供胎儿结构的高质量三维表面或半透明图像，类似于照片或X光图像，无需额外的昂贵工作站。在接受三维超声检查的204例患者中，该技术在62%（127/204）的病例中显示胎儿缺陷方面具有优势。在36%（73/204）的病例中，三维技术提供了相同的信息，在4例患有心脏畸形的胎儿（2%）中，由于数据采集期间的运动伪像，三维技术不利。展示了这种三维技术的技术优势和问题。
