Fig 5. Transverse MR images obtained in a 43-year-old woman with anaplastic astrocytoma. A and B, T2-weighted (A) (TR/TE, 3600/96 ms) and contrast-enhanced T1-weighted (B) (TR/TE, 670/14 ms) images showing a heterogeneous signal-intensity lesion with patchy enhanced areas in the left temporal lobe. C, Transverse rCBV map showing slight high-perfusion areas (arrow) in the medial portion of the temporal lesion. The maximum rCBV value within the tumor is 1.9. This patient survived 65 months after the initial MR imaging study.
