At the Burdenko Institute for Neurosurgery in Moscow, the following methods are used for the demarkation of cerebral gliomas: Beta-radiometry, rheometry = measurement of th electrical resistance of the cerebral tissue, staining of the tumour prior to the surgical intervention by means of a Serbinenko catheter, puncture biopsy as well as thermometry. The most frequently used techniques are beta-radiometry and rheometry. The methods are simple in application and the results are reliable. The accuracy of the localisation of a cerebral glioma by means of beta-radiometry is 98 per cent. For the impedance measurement a frequency of 1000 Hz is used. Liquids show the lowest and fibrous meningiomas the highest electrical resistance values. On an average the resistance of cerebral tumours is half as high as that of the average normal brain tissue. In almost all operations one tries to obtain an information about the extent and position of the glioma by means of brain puncture. A special needle probe has been designed to obtain tissue pieces for histological examinations. Experience has also been gained with ultrasonic probing and with temperature measurements of tumour and brain tissue. the interior of the tumours shows a 0.5 to 3 degrees C higher temperature.
在莫斯科的布尔坚科神经外科研究所，采用以下方法来界定脑胶质瘤：β射线测量法、流变学（即测量脑组织的电阻）、在手术干预前通过塞尔比年科导管对肿瘤进行染色、穿刺活检以及温度测量。最常用的技术是β射线测量法和流变学。这些方法应用简单且结果可靠。通过β射线测量法定位脑胶质瘤的准确率为98%。进行阻抗测量时使用的频率为1000赫兹。液体的电阻值最低，纤维性脑膜瘤的电阻值最高。平均而言，脑肿瘤的电阻仅为正常脑组织平均电阻的一半。在几乎所有手术中，人们都试图通过脑穿刺获取有关胶质瘤范围和位置的信息。已设计出一种特殊的针式探头来获取用于组织学检查的组织样本。在超声探测以及肿瘤和脑组织的温度测量方面也积累了经验。肿瘤内部的温度比周围高0.5至3摄氏度。
