Diagram of 2 SGA infants. An SGA infant without adverse outcomes after 36.4 weeks (a–i). a DWI at b = 100 mm2/s depicts the placenta. b ROI was drawn on a diffusion-weighted image (b = 100 mm2/s). c DWI-based vMRE map. d–h IVIM-based diffusion and perfusion pseudo-color maps of DDC, Alpha, f, D, and D*. i ADC map. An SGA infant with adverse outcomes after 36.1 weeks (j–r). j DWI at b = 100 mm2/s depicts the placenta. k ROI was drawn on a diffusion-weighted image (b = 100 mm2/s). l DWI-based vMRE map. m–q IVIM-based diffusion and perfusion pseudo-color maps of DDC, Alpha, f, D, and D*. r ADC map. ADC, apparent diffusion coefficient; Alpha, diffusion heterogeneity index; DDC, diffusion distribution coefficient; D, true diffusion coefficient; D*, pseudo-diffusion coefficient; DWI, diffusion-weighted imaging; f, perfusion fraction; IVIM, intravoxel incoherent motion; ROI, region of interest; SGA, small-for-gestational age; vMRE, virtual magnetic resonance elastography
