It will be interesting to see whether, and to what extent, the patient portal/21st Century Cures Act might shield physicians from liability

Yea I'm thinking of lacunae for a few reasons. The imaging finding of "infarct" vs the clinical entity of "stroke." Not every lacune signifies a remote infarct (could be from microhemorrhage or WMH). And that one rad's lacune is another's PVS. And you raise a good point re secondary prevention

Were unreported lacunae considered “strokes” in this study?
