Comparison
Ultra-low-dose chest-CT in the diagnostic work-up vs Chest X-ray (CXR)

Does not support routine ultra-low-dose CT over chest X-ray in the ED; confirms no meaningful short-term functional health benefit.
Does ultra-low-dose chest-CT improve functional health at 28 days compared to chest X-ray in patients suspected of non-traumatic pulmonary disease at the emergency department?
Routine use of ultra-low-dose chest CT instead of chest X-ray in the emergency department for suspected non-traumatic pulmonary disease does not improve short-term functional health and leads to more incidental findings.
