Fig 1. Sagittal diffusion-weighted images in a 25-year-old man with normal spine MR imaging findings obtained at the same level with 2 different techniques: EPI DWI at b = 600 mm²/s (A) and non-CPMG SS-FSE DWI at b = 600 mm²/s (B) and corresponding apparent diffusion coefficient (ADC) maps (C and D, respectively). Increased signal intensity, with better background suppression is noted with the non-CPMG SS-FSE technique. ADC values for the L3 vertebra are (mean ± SD) 0.51 ± 0.17 and 0.37 ± 0.14 x 10^–3 mm²/s for EPI and non-CPMG SS-FSE DWI, respectively.
