Two radiologists A and B (with experience of imaging diagnosis for 5 and 8 years, respectively) completed the image reading of T1WI, T2WI, DWI, T1-enhanced jointly without knowing the patients’ pathology results. Areas of tumor necrosis, cystic degeneration, and bleeding should be avoided when sketching. In case of disagreement, the two radiologists shall confer to reach a decision. The inter-class correlation coefficient (ICC) was then calculated with 30 lesions that were randomly chosen by the senior radiologist (Reader B). (1) ITK-SNAP (During sketching the tumor, maximum tumor diameter, tumor shape, mass effect, hemorrhage, cystic degeneration, necrosis, garland pattern enhancement, edema of the lesion were recorded at the same time.
