| 摘 要： | 目的探讨磁共振灌注成像(PW I)在脑膜瘤术前分型中的价值。方法39例经手术和病理证实的脑膜瘤患者,术前行PW I检查,计算并比较各型脑膜瘤的相对局部脑血流容积(rrCBV)和相对平均通过时间(rMTT)。结果血管瘤型脑膜瘤的rrCBV和rMTT分别平均为11.8、1.8,明显高于其他组织亚型。上皮细胞型和过渡型的rrCBV分别为8.3和7.5,之间无统计学意义;两者的rMTT则分别平均为1.5、1.3,统计学意义显著。纤维细胞型的rrCBV为4.0,明显低于其他组织亚型。结论PW I在脑膜瘤术前分型中具有重要价值。

| Abstract: | Objective To investigate the value of MR perfusion weighted imaging(PWI) features in typing meningioma preoperation.Methods MR perfusion weighted imaging was performed on 39 patients with pathologically proved meningioma.The relative regionalcerebral blood volume(rrCBV) and relative mean transit time(rMTT) were calculated.Results The rrCBV and rMTT of angioblastic meningiomas were 11.8 and 1.8,which were higher than that of the others subtype.The rrCBV of meningothelial meningiomas andtransitional meningiomas were 8.3,7.5 respectively,the rMTT of them were 1.5 and 1.3,there was statistically significant difference in rMTT between two groups,but no difference in rrCBV.The rrCBV of fibrous meningiomas was 4.0,which was lower than that of the others.Conclusion PWI is very useful in typing meninigioma preoperation. |
