Its great that they finally have an objective way to determine damage. But their assumption that knowing this will help in providing therapy is naive.

Objective Predicting outcome in patients with primary intracerebral
haemorrhage (ICH) in the acute stage can provide information to
determine the best therapeutic and rehabilitation strategies. We
prospectively investigated the predictive value of the functional
diffusion map (fDM) in the acute stage of ICH. Methods 47 patients with
ICH were enrolled for clinical evaluation and MRI within 24 h of symptom
onset and 5 days after ICH. Functional diffusion mapping prospectively
monitored the apparent diffusion coefficient (ADC) maps of
perihaematomal oedema. Consequently, the change in perihaematomal oedema
was classified into three categories: increased, decreased, or no
significant change. Clinical outcomes were evaluated 6 months after ICH
according to the modified Rankin Scale. Correlation between clinical
outcome and the fDMs was performed. Results Among the clinical
variables, thalamic haematoma, serum glucose level and National
Institutes of Health Stroke Scale scores were significantly different
between the good- and poor-outcome groups. The percentage of oedematous
tissue undergoing significant change between baseline and Day 5 was also
significantly different between the groups. Conclusion fDMs allow for
spatial voxel-by-voxel tracking of changes in ADC values. It may be
feasible to use fDMs to predict the functional outcome of patients with
ICH during the acute stage. Advances in knowledge The use of fDMs for
stroke study is demonstrated. fDMs may be more suitable to reflect the
pathophysiological heterogeneity within oedemas and may facilitate
another thinking process for imaging study of stroke and other
neurological diseases
