Visual identification of persistent high signal on high B value diffusion restriction sequence, and correlating low signal on ADC map is helpful in differentiation of tumor signal from T2 shine through (high signal on both diffusion restriction sequences and ADC map, see with mucin or high water content) and T2 dark through (high signal on both diffusion restriction sequences and ADC map, seen with fibrous scar). This evidence concerns the gene MUC5AC and neoplasm.
