In neurosurgery, ultrasound is useful in determination of the tumor location, differentiation between solid tumors and cystic components, as well as definition of the shortest and safest access to the mass. This study aims to evaluate the role of the intraoperative ultrasound in resection of pediatric brain tumors.
Intraoperative ultrasonography (conventional B-Mode) was performed in 25 pediatric patients with brain tumors pre-, during, and post-resection, in whom eight patients were supratentorial and 17 were infratentorial. Post-op Grayscale images of the brain tumors on conventional ultrasound were compared with the results of immediate postoperative magnetic resonance imaging.
The border of the tumor and post-resection residual tumor were more distinguishable from healthy brain on ultrasound during the operation. Improved definition of the tumor tissue from normal brain with ultrasound was demonstrated in all cases aiding in tumor resection.
Intraoperative ultrasound is suggested to be a useful imaging technique in defining the border between the tumor and healthy brain tissue pre-resection, in detecting residual tumor tissues after the resection of the mass, and in guiding to the shortest and safest access to the tumor during neurosurgery.
在神经外科手术中，超声有助于确定肿瘤位置、区分实体瘤与囊性成分，以及确定到达肿块的最短和最安全路径。本研究旨在评估术中超声在小儿脑肿瘤切除术中的作用。
对25例患有脑肿瘤的小儿患者在切除术前、术中及术后进行术中超声检查（传统B超模式），其中8例为幕上肿瘤，17例为幕下肿瘤。将传统超声检查的脑肿瘤术后灰度图像与术后即刻磁共振成像结果进行比较。
术中超声显示肿瘤边界及切除术后残留肿瘤与健康脑组织的区分更明显。在所有病例中，超声均显示肿瘤组织与正常脑组织的界限更清晰，有助于肿瘤切除。
术中超声被认为是一种有用的成像技术，可用于在切除术前界定肿瘤与健康脑组织之间的边界，检测肿块切除术后的残留肿瘤组织，并在神经外科手术中引导至肿瘤的最短和最安全路径。
