Chest x-ray (summary)

Dr Henry Knipe and Dr Jeremy Jones et al.

Chest x-rays are performed frequently in the assessment of a vast number of sick (and potentially sick) patients. 

A chest x-ray can be performed in the radiology department (usually with the patient standing up) or by the bedside. The quality of the radiograph is vastly superior if performed in the department, but this is not always possible - especially when the patient is sick.
