Quantitative Assessment of Restriction Spectrum Imaging Using a Diffusion MRI Phantom
Restriction Spectrum Imaging (RSI) is a multi-compartment diffusion MRI model developed to enhance sensitivity to restricted diffusion associated with tumoral tissue, addressing known limitations of the apparent diffusion coefficient (ADC). Unlike ADC, which...

Comparative Sensitivity of RSI and ADC to Tumor Cellularity at Ultra-High b-Values
Apparent diffusion coefficient (ADC) is a widely used marker of tumor cellularity in diffusion MRI, but ADC values depend on b-value selection and are prone to reduced tumor conspicuity in the presence of edema. Restriction Spectrum Imaging (RSI) leverages mu...
