FIG 2.

Anaplastic astrocytoma in a 44-year-old female patient. There is a mass in the T2-weighted (B) sequence showing a signal increase in the right thalamus. Also, there is a slight expansion in both T2-weighted (B) and the postcontrast T1-weighted (A) sequences. There is no significant enhancement in the postcontrast T1-weighted (A) MR image. There are no significant increases in perfusion in the mass localization derived from the DSC (C) perfusion color map (DSC rrCBF = 1.1). In the mpASL perfusion map (D), the perfusion increase in the mass localization can be seen clearly (ASL rrCBF = 3.3) (arrow).
