Detection rate observed by triphasic gadolinium-enhanced T1 sequences (Tri-Gd T1), steady-state free precession (SSFP), fat-suppressed fast spin-echo (fs-FSE) and diffusion-weighted imaging (DWI) sequences. The values are divided according to the different categories of lesions analyzed in the study. HCC: Hepatocellular carcinoma; FLLs: Focal liver lesions.
