To assess the perception of non-pregnant sonographers, sonologists and undergraduate students on the use of three-dimensional (3D) ultrasound technology in fetal medicine.
This was a study of two groups of non-pregnant subjects. Group I included 520 (305 female, 215 male) medical professionals who completed a questionnaire after attending a lecture on 3D imaging. Factors such as gender, career and having children were analyzed with respect to the attendee's responses about use of 3D ultrasound for medical purposes and for reassurance. Group II included 137 (75 female, 60 male, two unknown) undergraduate students from bioengineering, psychology and physiology classes who completed a questionnaire after attending a brief presentation on two-dimensional and 3D fetal imaging. Factors such as gender and area of educational interest were analyzed with respect to the students' responses about the use of 3D ultrasound for medical purposes and for parental-fetal attachment.
In Group I, 63% said that they would like to have a 3D ultrasound examination in the future, while 14% said that they would not. Common reasons given for wanting a 3D ultrasound exam in the future were for medical purposes (39%) or reassurance (18%). The main differences perceived between two-dimensional (2D) and 3D ultrasound were medical advantages (65%) and parental reassurance (28%). 62.4% of Group I thought 3D technology should be in wide use in obstetric ultrasound and 73.6% thought that 3D ultrasound would reassure parents carrying normal fetuses. Gender, age and career did not have a significant influence on perception of 3D ultrasound. In Group II, the majority (91%) said they could see a remarkable difference between 2D and 3D ultrasound. 83% responded that they would like to have a 3D ultrasound examination of their own baby in the future for the following reasons: 34% for the detailed picture, 31% for increased abnormality detection, 13% for reassurance or curiosity; 8% thought it would be unnecessary or a negative experience. Concerning parental-fetal attachment, 72% thought 3D ultrasound would have a positive effect. The majority of Group II (93%) thought 3D ultrasound would be valuable and 56% thought 3D ultrasound would assist in diagnosing fetal abnormalities. There was no significant relationship between gender, age or area of interest and the perception of 3D ultrasound.
Responses by sonographers and physicians suggest that 3D ultrasound will have a role in the future for medical indications and in reassuring patients carrying normal fetuses. Our results also suggest that undergraduate students believe that 3D ultrasound will be a valuable technique in obstetrics and that it will have a positive effect on parental-fetal attachment.
评估未怀孕的超声检查医师、超声科医生及本科生对三维（3D）超声技术在胎儿医学中应用的看法。
本研究针对两组未怀孕的受试者。第一组包括520名（305名女性，215名男性）医学专业人员，他们在参加了一场关于3D成像的讲座后填写了一份问卷。就参与者关于将3D超声用于医疗目的及获得安心感的回答，分析了性别、职业和是否有孩子等因素。第二组包括137名（75名女性，60名男性，2名信息不明）来自生物工程、心理学和生理学专业的本科生，他们在参加了一场关于二维和3D胎儿成像的简短介绍后填写了一份问卷。就学生们关于将3D超声用于医疗目的及对父母与胎儿情感联系的回答，分析了性别和教育兴趣领域等因素。
在第一组中，63%的人表示他们未来希望进行一次3D超声检查，而14%的人表示不愿意。未来希望进行3D超声检查的常见原因是出于医疗目的（39%）或获得安心感（18%）。二维（2D）和3D超声之间的主要差异体现在医疗优势（65%）和让父母安心（28%）。第一组中62.4%的人认为3D技术应在产科超声中广泛应用，73.6%的人认为3D超声会让怀有正常胎儿的父母安心。性别、年龄和职业对3D超声的看法没有显著影响。在第二组中，大多数人（91%）表示他们能看出2D和3D超声之间有显著差异。83%的人回答他们未来希望为自己未出生的宝宝进行一次3D超声检查，原因如下：34%是为了获得详细图像，31%是为了提高异常检测率，13%是为了获得安心感或出于好奇；8%的人认为没有必要或会是一次负面体验。关于父母与胎儿的情感联系，72%的人认为3D超声会有积极影响。第二组中的大多数人（93%）认为3D超声会很有价值，56%的人认为3D超声将有助于诊断胎儿异常。性别、年龄或兴趣领域与对3D超声的看法之间没有显著关系。
超声检查医师和医生的回答表明，3D超声在未来对医疗指征以及让怀有正常胎儿的患者安心方面将发挥作用。我们的结果还表明，本科生认为3D超声在产科中将是一项有价值的技术，并且它将对父母与胎儿的情感联系产生积极影响。
