| 摘 要： | 目的:探讨3D动脉自旋标记成像(ASL)全脑灌注成像技术在脑胶质瘤分级中的应用价值。方法:对25例经手术病理证实的低级别脑胶质瘤(Ⅰ~Ⅱ级,9例),高级别脑胶质瘤(Ⅲ~Ⅳ级,16例)行3D-ASL脑灌注成像扫描,测量各级别脑胶质瘤的脑血流量(CBF)及相对脑血流量(r CBF白质和r CBF灰质),并评价它们间的差异性。结果:高级别脑胶质瘤的CBF及r CBF白质、r CBF灰质均大于低级别胶质瘤,差异具有统计学意义(P0.001)。结论:3D-ASL脑灌注成像技术在评价脑胶质瘤的分级中具有重要应用价值。

| Abstract: | Objective:To explore the clinical value of three dimensional( 3D)whole brain arterial spin labeling( ASL)technique in brain glioma grad-ing. Methods:25 patients with brain glioma,were scheduled and diagnosed by pathology,including 9 Low - grade gliomas(Ⅰ ~ Ⅱgrade)and 16 High - grade gliomas(Ⅲ ~ Ⅳgrade),were underwent 3D - ASL perfusion imaging scan. The cerebral blood flow of each grade gliomas( CBF)and the relative cerebral blood flow of contralateral white matter(rCBFwhite)and the relative cerebral blood flow of contralateral grey matter(rCBFgrey)were measured. Results:Differences in High - grade gliomas and Low - grade gliomas were found,and the CBF、rCBFwhite and rCBFgrey in High - grade gliomas were higher than that in Low - grade gliomas(P ﹤ 0. 001). Conclusions:3D - ASL imaging technique is of great value in brain glioma grading. |
