A 23-year-old man with an osteosarcoma. (A) An axial T1-weighted image showing a hypointense left tibial osteosarcoma mass (arrow). (B) Axial T2-weighted image showing that the mass has high signal intensity (arrow). (C) Axial DW imaging reveals that the mass is hyperintense with a low ADC value (circled area: ADC = 0.985 × 10−3 mm2/s). (D) Axial contrast-enhanced T1-weighted image shows marked enhancement of the bone mass.
