Fig 2. A 46-year-old woman with L2 vertebral compression fracture. Sagittal T1-weighted image (A) and diffusion-weighted images obtained at the same level with 2 different techniques: EPI DWI at b = 600 mm2/s (B), non-CPMG SS-FSE DWI at b = 600 mm2/s (C), and corresponding apparent diffusion coefficient (ADC) maps (D and E, respectively). The compression is more readily appreciated on the non-CPMG SS-FSE images. ADC measured from L3 vertebral body is (mean ± SD x 10–3 mm2/s) 0.54 ± 0.14 and 0.38 ± 0.16 for EPI and non-CPMG SS-FSE DWI, respectively. ADC values measured from L2 vertebra are (mean ± SD) 1.63 ± 0.27 and 1.55 ± 0.24 x 10–3 mm2/s for EPI and non-CPMG SS-FSE DWI, respectively. This reflects the increased diffusion caused by the accompanying bone marrow edema.
