From: Non-invasively measured brain activity and radiological progression in diffuse glioma
Correlations between tumor volume changes and global brain activity. No significant correlations were found between brain activity and tumor volume change expressed in ml (upper panels) or percent tumor volume change (lower panels) after correction for the three associations between brain activity (broadband power, offset, slope) tested per change score type (ml and percentage). In eight patients, it was not possible to compute percent change, because the initial tumor volume was 0 ml. A.U. arbitrary units.
