A patient with spinal cord glioblastoma. a Sagittal T1 post-gadolinium MR image shows an enhancing intramedullary mass. b Corrected Vp (volumetric plasma volume) parameter of T1 perfusion is increased in the mass. c and d Increased Ktrans and AUC (area under the curve) in the mass but also in the posterior paraspinal soft tissues reflecting contrast extravasation due to postoperative changes. This case illustrates that T1 perfusion, particularly corrected Vp, allows detection of true tumour hypervascularisation
