Role of intraoperative Doppler Ultrasound in brain surgery

Abstract

Early investigation and excision are required for brain surgical lesions. When a patient has brain lesion, surgery ought to be their primary option. Treatment and total resection of a brain lesion are nearly always achievable. Maximal safe excision of brain lesions requires accurate and dependable intraoperative neuronavigation. The next frontier in navigation improvement has drawn a lot of interest in intraoperative magnetic resonance imaging, or intraoperative Magnetic Resonance Imaging (iMRI). Unfortunately, most centers throughout the world are unable to use iMRI due to its prohibitive cost and practical difficulties. By contrast, intraoperative ultrasonography (ioUS) is a low-cost instrument that can be seamlessly integrated into the theater's current setup and operational procedures. In the past, ultrasonography has been thought to have poor, artifact-prone image quality and be challenging to learn and standardize. However, with significant advancements in image quality and well-integrated navigation features over the past ten years, ioUS has undergone a dramatic evolution.
