Background：Contrast-enhanced ultrasound is a dynamic and continuous modality providing real-time view of vascularization and flow distribution patterns of different organs and *** order to evaluate the diagnostic significance of intraoperative contrast-enhanced ultrasound in assessing the resection degree of brain glioma by transmission electron microscopic （TEM） examination,it is important to have specific knowledge about contrast-enhanced ***：Ultrasound contrast was applied in operations of 120 cases of brain glioma,to evaluate the degree of tumor *** tissues were obtained the suspicious residual tumors surrounding the tumor *** sensitivity and specificity of the residual tumors were determined by the intraoperative ultrasound contrast according to TEM examination ***：There were 44 cases of low-grade gliomas and 76 cases of high-grade *** hundred and sixty biopsy tissues were *** sensitivity of intraoperative ultrasound contrast in diagnosing the residual tumor was 62.2%,while the specificity degree of it was 92.8%.The consistency coefficient of the ultrasound contrast diagnosis and TEM examination results was 0.584 （Kappa =0.584）,which was between 0.4 and 0.6,therefore it was of medium ***：intraoperative ultrasound contrast was of a high sensitivity and specificity in evaluating the excision degree of *** consistency of the residual tumor rate detected,respectively,by ultrasound contrast and TEM examination was of medium *** application of intraoperative ultrasound contrast can improve the resection rate of brain glioma.
