New technique for removable implantation of radionuclides in central nervous system neoplasm by ultrasonic guidance.
Introduced here is a new technique for the insertion of removable tubes into a brain tumor guided by a real-time ultrasonic B-mode scanner as a preliminary stage for interstitial brachytherapy of malignant brain tumors. Because tube insertion is conducted while watching in real time the tumor echo displayed on the cathode ray tube, the tube-positioning locations for insertion into the tumor can be freely selected with this technique. Additionally, the length of the tube that remains within the tumor bulk can be easily measured and recorded during the operation. Moreover, in that all these procedures can be carried out in the operating room, the operation will be performed under aseptic conditions and in a shorter time. These are the major advantages of this technique.
