The total internal OA score,
calculated as the sum of the hemoglobin score,
and blush score within the tumor interior,
correlated positively with histopathologic measures of tumor grade,
though the correlations did not achieve statistical significance (Figure 4).
the total external OA score,
calculated as the sum of the boundary zone and peripheral zone scores,
demonstrated an inverse relationship with histopathologic measures of tumor grade (Figure 5),
which achieved statistical significance for SBR-TOTAL,
though not for SBR-T.
High-grade tumors appeared to show prominent internal deoxygenated vessels and a relative paucity of external features (Figure 6).
Low-grade tumors conversely appeared to show minimal internal vascularity or deoxygenation with prominent boundary zone vascularity and deoxygenation and radiating vessels in the tumor periphery (Figure 7).
Intermediate-grade tumors appeared to display a mixture of internal and external OA features (Figure 8).
