Overview
An important test for pneumonia in unclear situations 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.
In some cases, chest CT (computed tomography) can reveal pneumonia that is not seen on chest x-ray.
X-rays can be misleading, because other problems, like lung scarring and congestive heart failure, can mimic pneumonia on x-ray.[1] Chest x-rays are also used to evaluate for complications of pneumonia. (See below.)
If a person is not getting better with antibiotics, or if the health care provider has concerns about the diagnosis, a cultureof the person's sputum may be requested.
Imaging
- X-rays of the chest (reveal areas of opacity). A normal chest x-ray makes 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.
- Computed tomography in situations of diagnostic dilema.
