Figure 1

The medical images of a 19-year-old male patient with OS in the distal femoral metaphysis of the left knee. The bone destruction area located in the femoral metaphysis on X ray films (A, B) (arrows) and tomography imaging (CT) (C, D). The OS was hypointense on T1WI (E) and hyperintense on T2WI (F) and DWI (G). The margins of OS were ill-defined. The lesion enhanced after contrast injection (H). I-L: The pseudocolour maps of ADC, D, D and derived from IVIM are displayed. M: HE staining (×100). The necrotic areas were marked with curve (H, I, J, K).
