Relationships between NODDI maps and duration of untreated psychosis (DUP) in first episode psychosis patients. Red scale colors indicate a positive correlation between DUP and NODDI indices, blue scale colors indicate a negative relationship between DUP and NODDI indices. Abbreviations: ND: neurite density map, ODI: orientation dispersion index map, FW: extracellular free water map, AF: arcuate fasciculus, ATR: anterior thalamic radiation, CB: cingulum bundle, CC: corpus callosum, EC: externa capsule, IFOF: inferior fronto-occipital fasciculus, ILF: inferior longitudinal fasciculus IC: internal capsule, SLF: superior longitudinal fasciculus. The color bar refers to z scores (for illustrative purposes a range from −0.4 to 0.4 was chosen). Blue/teal color range depicts areas of significant negative correlations between diffusion values and DUP, yellow/red color range depicts areas of significant positive correlations between diffusion values and DUP.
