The purpose of this study was to assess the impact of 3-/4-dimensional ultrasonography (3D/4DUS) on parental impressions of their fetus using preexamination and postexamination parental drawings.
One hundred one parents (32 male and 69 female) were asked to draw pictures of their fetus immediately before and after undergoing 3D/4DUS. A drawing assessment instrument was used to evaluate the fetal anatomy by 4 reviewers. Overall descriptive quality and a comparison of before and after images were assessed.
Reviewers judged the drawings as significantly different in 23% to 56% of cases, slightly different in 41% to 64%, and having no significant difference in 2% to 22%; some difference was identified in at least 78%. Reviewers familiar with ultrasonography were able to correctly predict which picture was drawn first in 78%. Differences identified were related to extremity positioning, personalized uterine environment, and artistic nature. No significant difference in the overall total scoring for anatomic differentiation before and after 3D/4DUS was found. A trend in drawing less anatomic structures after 3D/4DUS was discovered. Significantly fewer people drew hair after 3D/4DUS (P<.01) even when they had drawn hair before the 3D/4DUS. Similar significant differences were seen for the lower extremities (P<.01), with less detail being presented after the 3D/4DUS.
Differences were seen between drawings made before and after 3D/4DUS by parents. Drawings after 3D/4DUS emphasized structures seen during the 3D/4DUS examination and were more reality based, whereas drawings before 3D/4DUS were more iconographic and based on preconceived anatomic knowledge.
本研究旨在通过检查前和检查后父母所画的胎儿图，评估三维/四维超声检查（3D/4DUS）对父母对胎儿印象的影响。
101名父母（32名男性和69名女性）被要求在接受3D/4DUS检查前后立即画出他们胎儿的图像。4名评审员使用绘图评估工具对胎儿解剖结构进行评估。评估了整体描述质量以及前后图像的比较。
评审员判断，在23%至56%的病例中，绘图有显著差异，在41%至64%的病例中略有差异，在2%至22%的病例中无显著差异；至少78%的病例存在一些差异。熟悉超声检查的评审员能够在78%的情况下正确预测哪幅图是先画的。发现的差异与肢体位置、个性化子宫环境和艺术性质有关。3D/4DUS检查前后解剖结构区分的总体总评分没有显著差异。发现3D/4DUS检查后画出的解剖结构较少的趋势。3D/4DUS检查后画头发的人明显减少（P<0.01），即使他们在3D/4DUS检查前画过头发。下肢也有类似的显著差异（P<0.01），3D/4DUS检查后呈现的细节较少。
父母在3D/4DUS检查前后所画的图存在差异。3D/4DUS检查后的图强调了在3D/4DUS检查中看到的结构，更基于现实，而3D/4DUS检查前的图更具图像性，基于先入为主的解剖学知识。
