"Low dose CT chest has been suggested as a subsequent investigation to radiographs in stable patients with suspected radiolucent foreign body aspiration, as it can accurately identify clear airways that do not need bronchoscopy, or direct bronchoscopy to the affected airway(s) 5,6. An ultralow dose CT chest protocol for foreign body aspiration evaluation in children was shown to have a lower effective dose, and both better sensitivity and specificity, than a standard foreign body radiograph protocol making it the investigation of choice, if available 8."

"due to ossification centres in children, the medial ends of clavicles are difficult to visualise; therefore measuring the medial ends of the clavicle to the spinous process is not advised"
"bilateral decubitus views should demonstrate hyperinflation of the affected lung on both radiographs; in the obstructive foreign body there will be air-trapping and therefore hyperlucency of the dependent lung"
