Diffusion weighted imaging is commonly used in the placenta to characterise regions of differing structure and flow, including differences between the healthy and compromised placenta. Typically placental diffusion data is described by a combination of exponential decays with increasing diffusion weighting, but we have observed signals that show oscillations in signal or even increasing initial signal and are likely to relate to refocusing caused by coherent flows. By altering our diffusion fitting we can access information about flow patterns and provide more information regarding placental haemodynamics.
