Perfusion and diffusion contributions to apparent diffusion coefficient (ADC) across a spectrum of b-values. Schematic representation of relative contribution of both vascular and nonvascular motion to total ADC decay. The higher ADC vascular compartment is the primary contributor to total decay at gradient strengths less than 100 s/mm2, with contribution quickly falling and becoming negligible above a gradient strength of 200 s/mm2. Perfusion is the primary contributor to ADC at b50
