Figure 12.
The left femur G3 chondrosarcoma (A–E) of a 76-year-old male patient. Axial T2w image (A) shows a hyperintense bone lesion with a large posterior soft tissue mass presenting poor contrast enhancement on fat-suppressed T1w image (B). The lesion shows high signal on b = 0 DWI image (C), decreased signal on b = 1000 DWI image (D), and unrestricted pattern of diffusion on the corresponding ADC map (E, mean ADC: 2.303 × 10−3 mm2/s). The Ewing sarcoma (F–J) of the left iliac bone of a 31-year-old male patient. The tumor presents as an esofitic bone lesion with intermediate signal on axial T2w image (F) and high signal on axial STIR image (G). The lesion shows intermediate-high signal on b = 0 DWI image (H), higher signal on b = 1000 DWI image (I), and restricted pattern of diffusion on the corresponding ADC map (J, mean ADC: 0.899 × 10−3 mm2/s).
