Answer

The correlation between radiographic findings and severity of hypoxemia is highly variable. In addition, diuresis tends to improve infiltrates and volume overload tends to worsen them, irrespective of improvement or worsening in underlying ARDS.

For patients who begin to improve and show signs of resolution, improvement in radiographic abnormalities generally occurs over 10-14 days; however, more protracted courses are common.
