The role of three-dimensional pseudo-continuous arterial spin labelling in grading and differentiating histological subgroups of meningiomas

The CBFPTO value, rather than the CBFtumour value, from pCASL imaging may serve as a key factor in distinguishing different grades of meningiomas. Moreover, angiomatous meningiomas and fibrous meningiomas can be identified by CBFtumour value.
