Abstract：
Skeletal anomalies are rare, requiring a systematic ultrasound (US) examination of each skeletal part when there is suspicion of a skeletal dysplasia. Although US examination can provide good evaluation of the fetal bones and cartilage, ultra-low-dose three-dimensional (3-D) multi-detector computed tomography (CT) is a useful complementary tool that can significantly improve prenatal diagnostic accuracy in select cases. Given that ultra-low-dose fetal CT remains an irradiating technique, indications should result from a multidisciplinary consensus, acquisition protocols should be optimized and the reporting standardized. In this paper we discuss guidelines from the Fetal Imaging Task Force of the European Society of Paediatric Radiology for indications, protocols and reporting of ultra-low-dose fetal CT.
摘要：
骨骼异常很罕见,当怀疑骨骼发育不良时，需要对每个骨骼部分进行系统超声（US）检查。尽管美国检查可以很好地评估胎儿的骨骼和软骨，超低剂量三维（3-D）多探测器计算机断层扫描（CT）是一种有用的补充工具，可以显着提高某些病例的产前诊断准确性。鉴于超低剂量胎儿CT仍然是一种照射技术，适应症应该来自多学科共识，采集协议应优化，报告应标准化。在本文中，我们讨论了欧洲儿科放射学学会胎儿影像学工作组的适应症指南，超低剂量胎儿CT的协议和报告。
