Intraoperative ultrasound in determining the extent of resection of parenchymal brain tumours – a comparative study with computed tomography and histopathology

摘要

¶Background. Radical excision of parenchymal brain tumours is generally associated with a better long-term outcome; however, it is difficult to ascertain the extent of resection at surgery. We used intra-operative ultrasound [IOUS] to help detect residual tumour and define the tumour-brain interface.
