Advanced MRI (IMAGE) Medical College of Wisconsin Caption Image: Advanced MRI shows a 93% reduction in contrast enhancing tumor volume (T1+C: yellow arrow) in one rat responding to GaM treatment. IB’s quantitative Delta T1 (ΔT1) maps allow visualization of “true” tumor enhancement free of confounding blood products. IB’s relative cerebral blood volume (rCBV) noticeably decreased by day 50 (white arrow). IB’s fractional tumor burden maps (FTBs) provide the relative lesion proportions of tumor (red and pink) and non-tumor, necrosis (white).
