Objective:With the help of gtereotaxy and MRI three-dimensional imaging techonlogy,volumetric resection of brain glioma can be done.Methods:After fixing the frame on the patient's head,3-D images of the glioma can be got by MRI Scanning All of these information can help a neurosurgeon to design the scalp incision and select apropriate tryph and resect the gliomas completely with CUSA.During the resection,neurosurgeon can consider the optical trajectory to minimize risk to eloquent areas and vascular...

Objective:With the help of gtereotaxy and MRI three-dimensional imaging techonlogy,volumetric resection of brain glioma can be done.Methods:After fixing the frame on the patient's head,3-D images of the glioma can be got by MRI Scanning All of these information can help a neurosurgeon to design the scalp incision and select apropriate tryph and resect the gliomas completely with CUSA.During the resection,neurosurgeon can consider the optical trajectory to minimize risk to eloquent areas and vascular structures.Results:The planned volume was resected in 25 patients who had got brain gliomas.8 patients got transient palsy and recovered soon.Local seizure occured in 2 cares. One patient got aphasia who recovered later.No mortality due to the operation, no infection of the incision.Coclusion:The conbination of stereotaxy and MRI 3-D imaging technology provides a good control of brain gliomas resection to optimize amount of tumor removal with minimal trauma to surrounding brain tissues in a safe and cost-effective manner.

Objective To evaluate the potential of rCBV in preoperative assessment of histologic grading and vascularity of gliomas Methods MR imaging was performed in 32 patients by using a first-pass gadopentetate dimeglumine T  2-weighted echo-planar perfusion sequence followed by conventional imaging The perfusion data were deconvoluted to obtain a color map of relative regional CBV, and rCBV, rCBV ratio values were calculated with a nondiffusible tracer model The rCBV ratio of lesions was expressed as a percentage of the relative CBV of normal white matter The maximal rCBV ratio, rCBV of each lesion was correlated with the histopathologic grading of gliomas and microvessel density (MVD) obtained from samples of volumetric resection Results The maximal rCBV ratio in high-grade gliomas ( n = 18) varied from 5 30 to 14 80, with a mean of 8 32 ±1 68, and in the low-grade cohort ( n = 14), the maximal rCBV ratio varied from 0 89 to 5 40, with a mean of 2 93±1 19 The difference in rCBV ratio was statistically significant ( P <0 001; Student t test) The maximal rCBV in high-grade gliomas varied from 43 55 to 290 54, with a median of 113 60, and in the low-grade cohort, it varied from 9 66 to 168 76, with a median of 28 84 This difference in relative rCBV was statistically significant ( P =0 000, ∣ Z ∣=4 027, Wilcoxon test) The correlation between rCBV and MVD was obtained from linear regression analysis of rCBV and corresponding MVD Significant correlation was observed between them( r =0 87, P <0 001). Conclusions Echo-planar perfusion imaging appears to have great potential to improve preoperative evaluation of gliomas because there is good correlation between rCBV and MVD, and between perfusion and histologic grading A combination of PWI with conventional MR images can greatly improve the diagnostic accuracy before surgery
