Fig. 4From: Filter exchange imaging with crusher gradient modelling detects increased blood–brain barrier water permeability in response to mild lung infectionIntrasession Repeatability Mean normalised apparent diffusion coefficient (ADC’) against mixing times for the test and retest with mean ± s.e.m displayed for a the apparent exchange rate (AXR) model fit (n = 15) and b the crusher-compensated exchange rate (CCXR) model fit (n = 15). Bland–Altman plots of the c average vs the difference in AXR estimates (n = 15) and d average vs the difference in kin for each pair of test—retest measurements with the black dotted line showing 95% limits of agreementBack to article page
