Chest Radiograph (Pediatric) Foreign Body Aspiration

I get a called stat to ED upon arrival I see a 2 month with upper airway distress 
nurse says is croup, MD agrees but I keep assessing and I hear the upper airway noise is not stridor, epi is given an decadron IM, 

I look at the DR an tell him I don't think is croup and I asked him for an X-Ray 
I think is a foreign body. 

X-ray is done an this is what we get, oh yeah RT is always right.
