[Value of intra-operative ultrasound in detecting the boundaries of intra cranial gliomas].

Objective: To evaluate the application of intra-operative ultrasound (IOUS) in detecting the boundaries of intracranial gliomas.

Methods: One hundred and five consecutive patients with supra-tentorial glioma were included, male: 42 cases, female: 46 cases, age ranged from 15 - 67 years (mean 41 yrs), intra-operative ultrasound B was used to detect tumour boundaries before and after resection in 88 cases, tissues with suspicious echo was taken for verification by histological examination. And repeated MRI scan was received within 3 day after operation to judge the resection extent.

Intraoperative contrast-enhanced ultrasound for brain tumors.

Objective: The purpose of this study was to investigate the feasibility and value of the intraoperative contrast-enhanced ultrasound (CEUS) in resection for brain tumors.

Materials And Methods: Intraoperative CEUS was performed in 29 patients with brain tumors pre-resection, in whom 9 (of 29) patients underwent second intraoperative CEUS for assessing remained tumor tissue after initial resection. Gray-scale and color-flow images of the brain tumors on both conventional and CEUS were analyzed and compared with the results of surgical pathology.
