“…Research using diffusion parameters has been able to demonstrate correlation between abnormality in individual WM tracts, believed to reflect abnormal microstructural connectivity, and clinical outcomes (Counsell et al, 2008;Estep et al, 2014;Lee et al, 2011). Thus, a brain that looks normal on conventional imaging may still have injury to WM tracts demonstrated using these or other quantitative techniques (Mu et al, 2014;Scheck, Pannek, Fiori, Boyd, & Rose, 2014). Unfortunately, however, these techniques are not routinely available clinically, at least in Australia, and are mainly used in the research context.…”
