Synthetic Apparent Diffusion Coefficient for High b-Value Diffusion-Weighted MRI in Prostate

Figure 3

Inter-reader variation of ADC and contrast ratio. There was no significant difference between ADC values and synthetic ADC (sADC) values in the lesion (a and b) at b-2000. The difference between ADC and sADC in ROIs placed in normal tissue was significantly different (c and d). However, the contrast ratio of lesion and surrounding normal tissue increased significantly between DWI and sDWI for b-2000 (e and f). . The top row shows the result of Reader 1 (N = 15), and the bottom row shows that of Reader 2 (N = 12). (a) Reader 1 lesion. (b) Reader 1 normal. (c) Reader 1 DWI (b-2000). (d) Reader 2 lesion. (e) Reader 2 normal. (f) Reader 2 DWI (b-2000).
