Intraoperative use of ultrasound in brain surgery needs good understanding of the brain anatomy in ultrasound images. This study aims to compare ultrasound imaging of brain anatomical landmarks during surgery to perioperative computed tomography (CT), and perioperative magnetic resonance imaging (MRI) as demonstration for encouraging usage as low cost, available and hazardless device. In total; 350 patients were subjected to brain surgeries under ultrasound guidance using 2.5–8 megahertz (MHZ) transducers, at neurosurgery department Zagazig university hospital from January 2012 to January 2019. Brain anatomical landmarks were compared between ultrasound images, and perioperative images for safe, and confident surgeries. Various intracranial anatomical landmarks could be well-demonstrated by ultrasound through the open fontanel, or once the skull was opened, and during surgical work in real time fashion, facilitating surgical procedures, and avoiding complications. Real-time ultrasound is of great help during brain surgeries in delineating brain anatomical landmarks as well as MRI, and CT brain. The growing learning standard of intraoperative ultrasound (IOUS) use makes brain surgery more simple with avoiding brain shift problems, radiation exposure, and high cost of other intraoperative modalities.

术中超声成像对脑解剖标志物的示范性研究

在脑外科手术中术中使用超声需要对超声图像中的大脑解剖结构有很好的了解。这项研究的目的是将手术过程中脑部解剖标志的超声成像与围手术期计算机断层扫描（CT）和围手术期磁共振成像（MRI）进行比较，以鼓励使用低成本，可用和无害的设备。总共; 在2012年1月至2019年1月期间，在Zagazig大学医院神经外科中，使用2.5-8兆赫兹（MHZ）换能器在350例患者的超声引导下进行了脑外科手术。比较了超声图像和围手术期图像的大脑解剖标志，以确保安全，自信手术。超声通过开放的ultrasound门可以很好地演示各种颅内解剖标志，或打开颅骨后，以及在实时外科手术过程中，简化了外科手术程序并避免了并发症。实时超声波在脑外科手术中勾画出大脑解剖标志以及MRI和CT大脑时非常有用。术中超声（IOUS）使用的学习标准不断提高，避免了脑移位问题，辐射暴露以及其他术中方法的高昂费用，使得脑外科手术变得更加简单。
