(Left) Typical relative Cerebral Blood Volume (rCBV) maps extracted from perfusion MRI. (Right) rCBV as a function of tumor volume along with the performed 5^th order fit used to correlate the vascular density and the tumor size within the simulation setup according to the equation rCBV = 1.0 + (7.8 × 10⁻⁴)V_t − (3.4 × 10⁻⁷)V_t² + (5.8 × 10⁻¹¹)V_t³ − (4.4 × 10⁻¹⁵)V_t⁴ + (1.2 × 10⁻¹⁹)Vt⁵.
