Permeability versus Cerebral Blood Volume Measurement in Brain Tumor Evaluation: Comparative Clinical Value and Advice to Authors

n this issue of the AJNR , 2 different methods of MR blood- brain barrier permeability evaluation—first-pass T2*-weighted susceptibility (fpT2*) and steady-state T1 (ssT1) weighted imaging—are compared to each other and to dynamic susceptibility relative cerebral blood volume (rCBV) maps, in
