Abstract

Posterior fossa abnormalities are one of the most common indications for performing foetal magnetic resonance imaging (FMRI). Ultrasonography is the initial imaging modality for assessment of foetal posterior fossa. Abnormal findings on ultrasonography warrant further evaluation with FMRI because it offers excellent soft-tissue contrast resolution and multiplanar capabilities. The neurological prognosis of different posterior fossa anomalies varies widely. FMRI plays a crucial role in confirming the diagnosis, assessing the prognosis, and counselling patients regarding continuation of pregnancy and possible post-natal developmental outcome. In this review we present the imaging spectrum of posterior fossa anomalies that readers can encounter in practice, highlight salient points in favour of each diagnosis, and provide a simplified algorithmic approach to reach the final diagnosis.

摘要

后颅窝异常是进行胎儿磁共振成像（FMRI）最常见的指征之一。超声检查是评估胎儿后颅窝的初始成像方式。超声检查发现异常结果需要进一步进行FMRI评估，因为它具有出色的软组织对比分辨率和多平面成像能力。不同后颅窝异常的神经学预后差异很大。FMRI在确诊、评估预后以及为患者提供关于继续妊娠和可能的产后发育结果的咨询方面起着至关重要的作用。在本综述中，我们展示了读者在实践中可能遇到的后颅窝异常的影像学范围，强调支持每种诊断的要点，并提供一种简化的算法方法以达成最终诊断。
