X-rays are a form of electromagnetic radiation (like light). They are of higher energy, however, and can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray depending on density. X-rays can provide information about obstructions, tumors, and other diseases, especially when coupled with the use of barium and air contrast within the bowel.
A chest x-ray may reveal the following:
- Complications of pneumonia, including pleural effusions and abscesses
- White areas in the lung called infiltrates, which indicate infection
Other Imaging Tests. Computed tomography (CT) scans or magnetic resonance imaging (MRI) scans may be useful in some circumstances, especially when:
- A lung tumor is suspected
- Complications occur
- Patients do not respond to antibiotics
- Patients have other serious health problems
- Pulmonary embolism is suspected
- X-ray results are unclear
