Typical MR images of the L2 vertebral body metastasis with pathologic fractures reveal a sharply defined lytic lesion. Typical MR images of the L2 vertebral body metastasis with pathologic fractures reveal a sharply defined lytic lesion. The lesion has a mean ADC value of 1.7 × 10−4 mm2/s.A, Sagittal T1-weighted image (650/12; section thickness, 4 mm; intersection spacing, 1 mm; FOV, 32 cm; matrix, 512 × 512) shows low signal intensity (arrow).B, Sagittal T2-weighted fat-suppressed image (3000/99; section thickness, 4 mm; intersection spacing, 1–2 mm; FOV, 28–36 cm) shows heterogeneous abnormal signal intensity (arrow).C, Sagittal contrast-enhanced T1-weighted fat-suppressed image (416/12; section thickness, 4–6 mm; intersection spacing, 1 mm; FOV, 32 cm) shows enhancement (arrow).D, Sagittal diffusion-weighted image (5000/96.4; bandwidth, 125 kHz; FOV, 36 cm; matrix, 128 × 128; section thickness, 7.5 mm; intersection spacing, 1 mm) shows the lesion as bright area (arrow).
