DWI map, EADC map and ADC map showing the parenchymal part and cystic part of tumor at multiple levels. a DWI map: the overall ROI1 of tumor appears as mixed signals, with diffusion-restricted high signals in parenchymal part (ROI3) and equal signals in cystic part (ROI2); b EADC map: ROI1 0.134, ROI2 0.0752, ROI3 0.256; c ADC map ROI1 2.102 × 10⁻³ mm²/s, ROI2 2.601 × 10⁻³ mm²/s, ROI3 1.372 × 10⁻³ mm²/s
