Clinical Applications of Contrast-Enhanced Perfusion MRI Techniques in Gliomas: Recent Advances and Current Challenges

Figure 6

Discrimination of RN from recurrent GBM using DCE-MRI (a) and DSC-MRI (b). Contrast-enhanced T1WI demonstrates similar contrast enhancement in recurrent glioblastoma (top row) and RN (bottom row). Corresponding rCBV and maps show significant difference between these two entities, with higher and rCBV for recurrent tumor (top row) but low for RN (bottom row).
