中文摘要:
      研究目的:探讨术中双功超声在脑少突胶质细胞瘤的应用价值。方法:回顾分析7例经病理证实的少突胶质细胞瘤的术中双功超声图像。术中超声(Intraoperative Ultrasound,IOUS)由同一检查者按照统一图像质量标准存储、分析。B模式评估病灶位置、大小、回声、边界、形态、其他征象,D模式评估病灶多普勒血流信号。结果:7例少突胶质瘤的最大径线平均值为5.2 cm,病灶边缘距脑膜<1 cm者占71.4%。85.7%为稍强回声团块,85.7%边界清晰,57.1%形态不规则,71.4%伴有不同形状的高回声,71.4% Adler血流分级为3级。结论:IOUS的B模式可用于脑少突胶质细胞瘤的实时定位及术中监测,D模式血流信息有助于定位脑部重要血管,进行术中预警。声像图中出现不同形状的高回声,后方不伴声影,提示钙化可能性大,对胶质瘤的影像学分级有一定帮助。
英文摘要:
      Objective:To explore the value of intraoperative ultrasound (IOUS) in oligodendroglioma. Methods:The intraoperative ultrasound images of 7 patients with supratentorial oligodendroglioma confirmed by pathology were analyzed. IOUS images are stored and analyzed by the same examiner according to the unified image quality standard. B mode is used to evaluate the location, size, echo, boundary, shape and other signs of the lesions, and D mode is used to evaluate the Doppler blood flow signals of the lesions. Results:The mean maximum diameter of 7 oligodendrogliomas is 5.2 cm, and 71.4% of the lesions are less than 1 cm from the edge of the lesion to the meninges. 85.7% has slightly hyperechoic mass, 85.7% has clear boundary, 57.1% has irregular shape, 71.4% has different shapes of hyperechoic and 71.4% has Adler blood flow classification of Grade 3. Conclusions:The B mode of IOUS can be used for real-time locating and intraoperative monitoring of oligodendroglioma. The D mode of blood flow information can help locate the important blood vessels in the brain and carry out intraoperative early warning. There are different hyperechoic patterns, such as spot, slice, arc, linear and nodular, in the brain lesion images without acoustic shadow at the back, indicating the high possibility of calcification, which is helpful to the imaging classification of glioma.
