Overview
An important test for making a diagnosis of pneumonia is a chest x-ray. Chest x-rays can reveal areas of opacity (seen as white) which represent consolidation. Pneumonia is not always seen on x-rays, either because the disease is only in its initial stages, or because it involves a part of the lung not easily seen by x-ray.
Chest X-Ray
Indications
Patients with the following conditions should be evaluated with a chest X-ray:[1]
- Fever (>37.8° C / 100° F)
- Tachypnea (> 20 breaths/min)
- Tachycardia (> 100 bpm)
- Decreased breath sounds and crackles in the physical exam
Findings
- X-rays of the chest reveal areas of opacity.
- A normal chest x-ray makes community-acquired pneumonia (CAP) less likely; however, CAP is sometimes not seen on x-rays because the disease is either in its initial stages or involves a part of the lung not easily seen by x-ray.
- X-rays can be misleading, because other problems, like lung scarring and congestive heart failure, can mimic pneumonia on x-ray.[2] Chest x-rays are also used to evaluate for complications of pneumonia.
- Chest x-ray findings are usually nonspecific in viral pneumonia.
- Computed tomography is used in situations when the diagnosis is not clear with a chest x-ray
Hospital Acquired
- The American Thoracic Society recommends that all patients with a suspicion of nosocomial pneumonia should have a chest x-ray to confirm diagnosis and determine the severity of the disease.[3]
- A chest X-ray also helps to determine pleural effusions or cavitations, as a possible complication.
- Ideally, the chest X-ray should be posteroanterior and lateral, but this will depend on the patient's condition.
- Findings include the following:[4]
- Unilateral or bilateral consolidation
- Air bronchogram
- Pleural effusion
- Cavitation
- Ground glass opacities
- Chest x-ray is also used to assess improvement or lack of clinical response in hospitalized patients.
