“…Restriction spectrum imaging (RSI-MRI) is an advanced imaging technique that shows improved conspicuity and differentiation of solid tumors compared to traditional diffusion weighted imaging methods [10,11]. The RSI-MRI method can differentiate hindered vs. restricted diffusion, thought to correspond to the extracellular and intracellular water compartments, respectively [12].…”

“…In fact, the presence of impeded diffusion following bevacizumab treatment of malignant gliomas correlated with improved overall survival, suggesting prognostic value. RSI demonstrated increased sensitivity in detecting areas of persistent restricted diffusion relative to conventional DWI, and when combined with relative cerebral blood volume measurements may be able to differentiate BRIA from residual tumor . Prior manuscripts have presented and discussed the promising results using RSI in intracranial neoplasms …”

“…While the strength of RSI comes from being able to isolate specific water fractions (e.g., intracellular water), other diffusion‐based techniques may prove more powerful for certain pathological settings not focused on identifying highly cellular tissues. For example, conventional DWI proves to be better than RSI at identifying edema in patients with CNS malignancy . Future studies will be needed to clarify the pathological questions best suited to each unique diffusion‐based technique.…”

“…In neuro-oncology, cell density and prominent vascularization reflect heterogeneous patterns of malignancy than can be prognostically assessed by combinations of DWI and perfusion imaging 24 to differentiate tumor progression and therapy-related effects. 25 …”
