Figure 17

An 18-year-old boy with spindle-cell sarcoma of the right thigh. (A) ADC map demonstrates high ADC values (>1.5× 10−3 mm2/s): mean value of entire tumor, 2.13 × 10−3 mm2/s (ROI 3); central necrosis (ROI 1), 2.94 × 10−3 mm2/s; relatively high cellular area, 1.64 × 10−3 mm2/s (ROI 2). Corresponding high cellular area (ROI 2) demonstrates solid component on (B) T2-weighted MR image with fat suppression, and more contrast enhancement than area of necrosis (ROI 1) on (C) precontrast and (D) postcontrast T1-weighted MR images.
