Seventy-two lesions were demonstrated in 70 patients who were examined using intraoperative real-time ultrasonography. Fifty-five lesions were supratentorial and 17 were infratentorial. The neurosurgeon used ultrasonography to evaluate his operative field before, during, and after resection. Nineteen lesions contained cystic components. In eight cases, ultrasonography added information not provided by CT including definitive characterization of cystic components and loculations or localization of solid masses within the cysts. Biopsy of 13 lesions was performed under ultrasonic guidance. In all cases, the biopsy probe could be seen passing through the lesions leaving an echogenic trail, possibly blood filled, after the probe had been removed. Three lesions with diameters of less than 1 cm were localized and successfully removed under ultrasonic guidance. Intraoperative real-time ultrasonography is a safe and reliable technique, and it can be a valuable aid to the neurosurgeon.
在70例接受术中实时超声检查的患者中发现了72个病灶。55个病灶位于幕上，17个位于幕下。神经外科医生在切除术前、术中和术后使用超声评估手术视野。19个病灶含有囊性成分。在8例病例中，超声提供了CT未提供的信息，包括囊性成分的明确特征以及囊肿内实性肿块的分叶或定位。在超声引导下对13个病灶进行了活检。在所有病例中，活检探头穿过病灶后均可看到，移除探头后留下一条可能充满血液的强回声轨迹。3个直径小于1 cm的病灶在超声引导下被定位并成功切除。术中实时超声检查是一种安全可靠的技术，对神经外科医生有很大帮助。
