Bronchiolitis is inflammation of the small airways, most often in infants and young children.
It usually starts like a cold with a blocked or runny nose and cough, then may lead to fast breathing, wheezing, poor feeding, irritability, or reduced wet diapers in babies.
Imaging is usually not needed in straightforward bronchiolitis, but it can help if symptoms are unusually severe, prolonged, or there is concern about pneumonia or another diagnosis.
Imaging is not always needed, but chest X-ray may be used when symptoms are severe, prolonged, or atypical.
Treatment is usually supportive with hydration, oxygen when needed, and close clinical monitoring.
