目的探讨颅内肿瘤的术中超声成像特征和超声的技术应用。方法对48例原发颅内肿瘤和转移瘤进行术中实时超声成像,分析不同类别肿瘤的回声形态。结果48例颅内肿瘤均为不同于周围脑组织回声性质的病变而被准确识别和定位。实质性低级别胶质瘤以规则的脑沟为边界,中心性坏死在高级别胶质瘤中最常见,随胶质瘤级别的增高,回声的不均匀性增加;脑膜瘤表现为边界清晰的均匀高回声,术中超声可显示窦旁脑膜瘤对静脉窦的压迫或侵犯;海绵状血管瘤表现为边界清楚的实质性的高回声团块,可检出的最小直径为9mm;转移瘤表现为强回声环和不均匀的回声中心。瘤周水肿的信号强度介于肿瘤和脑组织之间。结论术中超声能为颅内肿瘤的准确定位和描述细节提供有价值的信息,合理应用神经超声技术可使病变成像更清晰。
Objective To explore intraoperative ultrasound imaging features of intracranial tumors and the application of ultrasound technology. Methods 48 cases of primary intracranial tumors and metastases underwent real-time intraoperative ultrasound imaging, analysis of different types of tumors echo morphology. Results 48 cases of intracranial tumors are different from the surrounding brain tissue echo characteristics of the lesions were accurately identified and localized. Substantial low-grade glioma to the rules of the sulcus as the border, central necrosis in high-grade glioma is the most common, with the glioma level increased, echo heterogeneity increased; meningiomas showed a clear boundary Uniform high echo, intraoperative ultrasound can show sinus venous sinus meningioma or violations; cavernous hemangiomas showed clear boundary of the substantial hyperechoic mass, the smallest diameter can be detected 9mm; metastatic tumor performance For the strong echo ring and uneven echo center. Peripheral edema signal intensity between the tumor and brain tissue. Conclusion Intraoperative ultrasound can provide valuable information for the accurate localization and description of intracranial tumors. Reasonable application of ultrasound can make the imaging of the lesion clearer.
