Comparisons of contrast ratio (CR) for each diffusion-weighted imaging (DWI). The CR for cancerous and non-cancerous lesions of each DWI. The CR of measured DWls with b = 2000 s mm−2 (mDWI2000) was significantly lower than that of all other computed DWls (cDWIs). *p < 0.05, **p < 0.01. b-value combinations: 0–100 s mm−2 (cDWl0–100); 0–500 s mm−2 (cDWl0–500); 100–500 s mm−2 (cDWl100–500); 0–1000 s mm−2 (cDWl0–1000); 100–1000 s mm−2 (cDWl100–1000); 500–1000 s mm−2 (cDWl500–1000).
