Real-time virtual sonography (RVS) is a new technique that synchronizes real-time ultrasonography (US) and multiplanar reconstructed magnetic resonance imaging (MRI). The purpose of this study was to evaluate the feasibility and ability of RVS to assess the main pathologies in fetuses with suspected US anomalies.
Real-time virtual sonography (Hitachi, HI VISION Ascendus) was offered to 30 patients who had undergone fetal MRI. The acquired MRI image dataset was loaded into the fusion system and displayed together with the real-time US image. The ability of RVS to assess the main anatomical sites and fetal anomalies was evaluated.
Real-time virtual sonography was technically possible in all cases. From a total of 30 patients, RVS helped the diagnosis in 10 cases. In 15 cases of encephalic pathology, fusion imaging improved the accuracy of the diagnosis; in the other 5 cases, MRI was superior to US even when using the RVS.
This is a study on the feasibility and practical use of RVS. Thanks to information from both US and MRI, RVS allowed better identification of the fetal pathologies and improved the performance of the ultrasound examination. In our experience, it was really helpful in pathologies that would benefit from US follow-up.
实时虚拟超声（RVS）是一种将实时超声（US）与多平面重建磁共振成像（MRI）同步的新技术。本研究旨在评估 RVS 评估疑似 US 异常胎儿主要病理的可行性和能力。
为 30 名接受胎儿 MRI 的患者提供实时虚拟超声（日立 HI VISION Ascendus）。将获得的 MRI 图像数据集加载到融合系统中，并与实时 US 图像一起显示。评估 RVS 评估主要解剖部位和胎儿异常的能力。
在所有情况下，实时虚拟超声均具有技术可行性。在总共 30 名患者中，RVS 有助于诊断 10 例。在 15 例脑部病变中，融合成像提高了诊断的准确性；在另外 5 例中，即使使用 RVS，MRI 也优于 US。
这是一项关于 RVS 可行性和实际应用的研究。得益于 US 和 MRI 的信息，RVS 能够更好地识别胎儿病变，并提高超声检查的性能。根据我们的经验，它在那些受益于 US 随访的病变中确实很有帮助。
