Infant thoraco-abdominal diffusion-weighted imaging (DWI). Axial T2-weighted magnetic resonance (MR) imaging (left; a - c) and apparent diffusion coefficient (ADC) maps from DWI sequences (right; d - f) in a 2-month-old boy who underwent MR imaging for a congenital sacral abnormality (not shown). Axial slices illustrate the lungs (a), liver and spleen (b) and kidneys (c), with corresponding regions of interest drawn on ADC maps over the lungs (d), liver and spleen (e), renal cortex (f) and muscle (not shown). No appreciable ADC signal was detected from the lungs (d)
