- EDITOR'S CHOICEAdult BrainOpen AccessProgressing Bevacizumab-Induced Diffusion Restriction Is Associated with Coagulative Necrosis Surrounded by Viable Tumor and Decreased Overall Survival in Patients with Recurrent GlioblastomaH.S.

The authors explored regions of diffusion restriction following bevacizumab therapy in patients with glioblastoma by 1) analyzing tissue samples from patients at postmortem to pathologically confirm tumor cellularity or coagulative necrosis and 2) assessing the patient populationto determine the effect that these lesions have on overall survival. The postmortem examinations were performed on 6 patients with recurrent glioblastoma on bevacizumab withprogressively growing regions of diffusion restriction. ADC values were extracted from regions of both hypercellular tumor and necrosis. They conclude that progressive diffusion-restricted lesions were pathologically confirmed to be coagulative necrosis surrounded by viable tumor and associated with decreased overall survival.

Both dynamic susceptibility contrast perfusion with bookend T1-calibration and pseudocontinuous arterial spin-labeling have been used recently for CBF quantification in relapsing-remitting MS. The authors compared pseudocontinuous arterial spin-labeling CBF with the bookend technique in a prospective cohort of 19 healthy controls, 19 subjects with relapsing-remitting MS without cognitive impairment, and 20 subjects with relapsing-remitting MS with cognitive impairment. Voxelwise paired t tests revealed no significant CBF differences between techniques after normalization of global meanintensities. They conclude that there is agreement between pseudocontinuous arterial spin-labeling and bookend technique CBF measurements in healthy controls and patients with relapsing-remitting MS.
