Qualitative evaluation of the realism of the low-resolution (LR) series simulated using FaBiAN v1.2 and FaBiAN v2.0 for 29 subjects, in the three orthogonal orientations, by two independent experts in pediatric neuroradiology (Expert #1) and in neuroradiology (Expert #2). Experiment 1 (top row) consisted in comparing images generated for every subject by both implementations of the simulation framework. The cumulative count of the most realistic synthetic LR series is represented over the gestational age, according to each expert, showing a net preference for FaBiAN v2.0 (between 96% and 100% of the images evaluated as the most realistic by Expert 1 and Expert 2 respectively) over FaBiAN v1.2 throughout fetal brain maturation. Experiment 2 (bottom row) further aimed at evaluating the realism of the simulated LR series independently. The violin plots show the distribution of the ratings (between 1-poorly realistic and 5-highly realistic) of every image by each expert. Overall, the LR series simulated by FaBiAN v2.0 were rated as more realistic than the ones generated using FaBiAN v1.2.
