| ABSTRACT |
|
Recent technological advances in ultrasound instrumentation have resulted in equipment that will image in "real-time" slices of the human brain similar in quality to computerized tomography(CT). Multiple authors have attested to its usefulness in locatin, characterizing, and facilitating in the biopsy or removal, or both, of intracerebral masses. In this study, the author has examined the efficacy of intraoperative neurosurgical ultrasound in 18 patients who were admitted to the Department of Neurosurgery, Kyung Hee University Hospital. The results were as follows : 1) It can provide critical assistance in precise localization of subcortical masses, since in many instances the overlying surface of brain provides no clue for localization. 2) This technique is very useful for the identificantion of deep lesions, provding infromation about their solid and cystic components and about the shortest route of access to tumor.
3) It provides precise information to help guide biopsy needles into deep lesions, and to confirm their presence within the lesion itself. 4) The system is highly accurate in visualizing ventricular catheters during and after their placement. 5) The system is inherently safe for the patient and the operating room personnel since there is no radiation exposure. |
