Fig. 4From: Experimental phantom evaluation to identify robust positron emission tomography (PET) radiomic featuresExample of radiomic features robust to different protocols (left) and radiomic features strongly correlated (right). In our study the different protocols (A and B) were PET/CT system (analogic vs digital), voxel size of reconstruction (8 mm3 vs 64 mm3), CT metal artifact (with vs without), and PET segmentation approach (ground truth vs 40% vs COA)Back to article page
