| Abstract: | Based on the results of a comparative study (magnetic resonance imaging and/or computed tomography with a morphological study) in 11 patients with malignant brain glioma, the authors have ascertained that the extent of perifocal edema cannot fully reflect the degree of impairment of the blood-brain barrier (BBB) in the tumor vessels: the signs of BBB impairment were found in 47.1% of the tumor vessels in patients with insignificant edema and in only 15% of the vessels in those with significant edema. |
