The following significant (p < 0.05) correlations were shown in the glioblastoma group (n = 37): in ROI1 (highly perfused enhancing tumor part) Bcl2 EA—AWF (rs = −0.504), Bcl2 EA—AxIAD (rs = −0.385), Bcl2 EA—FA (rs = −0.476), Bcl2 EA—MD (rs = 0.421), Bcl2 EA—RadIAD (rs = 0.444), Bcl2 EA—TORT (rs = −0.501), in ROI2 (perifocal infiltrative edema zone) Ki67 LI—AK (rs = −0.434), Ki67 LI—MK (rs = −0.381), Bcl2 EA—AWF (rs = −0.448), Bcl2 EA—MK (rs = −0.522), Bcl2 EA—RK (rs = −0.497). The gene discussed is BCL2; the disease is glioblastoma.
