螺旋计算机断层扫描 (CT) 的技术优势可能证明对儿童的影响比对成人的影响更大。尽管有改善成像的潜力，但只有有限的科学证据表明儿童螺旋 CT 可以改善诊断。实际上，由于螺旋 CT 已成为标准 CT (1)，因此几乎不需要进行此验证，并且儿科螺旋 CT 的重点应该是如何进行，而不是为什么进行。因此，本文的目的是通过强调技术并将其与当代应用联系起来，展示儿科螺旋 CT 的独特之处。由于 CT 的大部分身体应用涉及胸部、腹部和骨盆 (2)，因此讨论将仅限于这些区域，并将重点放在螺旋 CT 上。没有差异的问题，例如镇静和口服造影剂，将不会被讨论。选择疾病过程的例子来说明特殊技术或螺旋技术在儿童中的应用。有关儿童身体 CT 具体应用的更多详细信息，请参阅最近的几篇评论 (3-5)。
The technical advantages of helical computed tomography(CT) may prove to have even greater effect in children than has been shown in adults. Despite this potential for improved imaging, there is only limited scientific evidence that helical CT in children has resulted in improved diagnosis. In effect, there is little need for this validation since helical CT has become standard CT (1), and the focus for pediatric helical CT should be how, not why. Therefore, the purpose of this article is to present the unique aspects of pediatric helical CT by emphasizing techniques and relating them to contemporary applications. Since the majority of body applications in CT involve the chest, abdomen, and pelvis (2), discussion will be limited to these regions and will focus on helical CT. Issues that do not differ, such as sedation and oral contrast material, will not be discussed. Examples of disease processes are selected as an illustration of a special technique or application of helical technology in children. More detailed information on specific applications for body CT in children is available in several recent reviews (3-5).
