CE-MRI and PWI of the postoperative HGG patient before radiotherapy. (a). CE-MRI and PWI images for a 60-year-old male patient who had double frontal astrocytoma (WHO Grade III). The PWI showed high rCBV of 1.86 in the surgical cavity (iii), while no nonuniform contrast enhancement was found in the same region in the T1 axial image (i) and CE-MRI axial image (ii). (b). CE-MRI and PWI images for a 64-year-old male patient who had the right fronto-parietal glioblastoma (WHO Grade IV). The PWI showed high rCBV of 1.62 in the non-surgical area (ii), but the CE-MRI axial image did not illustrate contrast enhancement (i). (c). CE-MRI and PWI images for a 40-year-old male patient who had left frontal glioma (WHO Grade IV). CE-MRI, nonuniform contrast enhancement in the surgical cavity (i), and PWI shows high rCBV of 2.99 (ii). (d). CE-MRI and PWI images for a 63-year-old male patient who had left parieto-temporal lobe glioblastoma (WHO Grade IV). CE-MRI, nonuniform contrast enhancement in the surgical cavity (i), and PWI shows rCBV is normal (ii).
