This table compares findings on 8T gradient echo MRI to histopathologic findings from corresponding foci within the patient’s brain studied here. Comparisons include whether tumor was identified in each of the modalities (8T and histopathology), vessel size relative to normal brain tissues and vessel density relative to normal tissues
