磁敏感加權成像血管結構半定量評分法對顱內(nèi)膠質(zhì)瘤分級的診斷價值
[Abstract]:Objective to evaluate the diagnostic value of magnetic sensitivity weighted imaging (susceptibility weighted imagingsSWI) in the diagnosis of intracranial gliomas. Methods the imaging data of 36 cases of gliomas (15 cases of low grade gliomas and 21 cases of high grade gliomas) were retrospectively analyzed. After post-processing, the minimum intensity projection (minimum intensity projectionMinIP was obtained. The number of neovascularization in glioma was observed by two senior neuroimaging diagnostics with blind method and the difference between the two groups was analyzed. Results in 15 cases of low grade glioma, 6 cases had 0 score, 9 cases had 1 score, 21 cases had high grade glioma, 18 cases had blood vessel score, 2 cases had 3 points, 1 case had blood vessel score, 1 case had blood vessel score. There was significant difference in blood vessel score between low grade glioma group and high grade glioma group (Z value -5.327 P value 0.05). Conclusion the semi-quantitative scoring method of vascular structure in magnetic sensitivity weighted imaging is helpful for the initial grade diagnosis of high and low grade intracranial gliomas.
