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.
