title: [Application of intraoperative contrast-enhanced ultrasound in different pathological grades of glioma].
abstract: OBJECTIVE
  To explore the feasibility and value of intra-operative contrast-enhanced ultrasound in different pathological grades of glioma.
  
  
  METHODS
  A total of 46 patients with glioma were selected to undergo the contrast-enhanced ultrasound. They were divided into 3 groups according to their pathological grades.
  
  
  RESULTS
  All 46 tumors were hyperechoic after examinations and the borders became much more distinct. Different level of tumors had their representative ultrasonic findings.
  
  
  CONCLUSIONS
  Intraoperative contrast-enhanced ultrasound is quite useful for determining the position and border of tumors. And it is also excellent in detecting the residual tumor tissues post-operatively. And it can improve the resection accuracy and operative precision, especially for Grade IV glioma with internal necrosis, cyst and surrounding brain edema.
