Where the Future Goes: What do we Need to Know in the ARDS and how Lung Imaging Can Deal with this?

Acute respiratory distress syndrome (ARDS) remains a clinical challenge for intensivists, despite extensive experimental and clinical research over the past thirty years. Meanwhile, lung imaging techniques have emerged as invaluable non-invasive tools and have considerably modified and improved management of many lung pathologies. The purpose of this review is to list major unanswered questions in ARDS and to speculate on how lung imaging may provide answers in the near future.
