Chest X-ray (cont.)
Who can interpret chest X-rays?
Many doctors are trained to interpret chest X-rays. In addition to
radiologists, who have special training in reading all radiology films, primary
care physicians, internists, pediatricians, emergency room doctors,
anesthesiologists, heart doctors (cardiologist), lung doctors (pulmonologist)
and lung surgeons are the doctors who frequently interpret chest X-rays as a
part of their routine practice.
What can be seen on normal chest X-ray?
Normal chest X-ray shows normal size and shape of the chest wall and the main
structures in the chest.
As described earlier, white shadows on the chest X-ray signify solid
structures and fluids such as, bone of the rib cage, vertebrae, heart, aorta,
and bones of the shoulders. The dark background on the chest X-rays represents
air filled lungs. These lung fields are seen on either side of the heart and the
vertebrae located in the center of the film.
What are some common chest X-ray abnormalities?
Chest X-ray is generally used in combination with other clinical data such
as, physical examination and the patient's history and symptoms. It can also be
used in combination of other radiology test to support, confirm, or exclude many
conditions or diagnoses.
A chest X-ray can be used to define abnormalities of the lungs such as
excessive fluid (fluid overload or pulmonary edema) fluid around the lung
(pleurisy),
pneumonia, bronchitis, asthma, cysts, and cancers. Heart
abnormalities, including fluid around the heart (pericarditis),
an enlarged heart (cardiomegaly), heart failure, or abnormal anatomy of the
heart can be revealed on the films. Certain bony structures of the chest and
broken bones (rib fracture) or abnormalities of the bones of the spine
(vertebral
fracture) in the chest can often be detected.
