Fig 3. — Pathologically confirmed meningioma (WHO grade I/III).

A, Axial contrast-enhanced T1-weighted (600/14) MR image.

B, Axial gradient-echo (1000/54) pMRI image with an rCBV color overlay demonstrates high rCBV throughout the lesion.

C, Axial gradient-echo (1000/54) axial pMRI image with SD25 depicts a decrease in signal intensity after 25 seconds.

D, Normalized signal intensity plotted against time for the white matter (squares) and the lesion (triangles). The lines represent the fitted curves derived by using the first-pass PM algorithm. The return to baseline is more rapid in typical meningiomas than in atypical meningiomas.
