Fig. 2From: Differentiation of small (≤ 3 cm) hepatocellular carcinomas from benign nodules in cirrhotic liver: the added additive value of MRI-based radiomics analysis to LI-RADS version 2018 algorithmExtraction of image segmentation and texture features. Using the software package MaZda 4.6 for texture calculation for a 78-year-old man with a pathologically proven HCC, regions of interest (ROIs) were manually delineated in the largest cross-sectional area of the lesion in the in phase T1W image (a), FS-T2W image (b), and ADC maps (c). A total of 279 quantitative texture features from six statistical image descriptors were extracted for each ROI, thus a total of 837 features based on the three sequences were determined for each lesion (d)Back to article page
