Who Needs a Chest X Ray?
People who have symptoms such as shortness of breath, chest pain, chronic
cough (a cough that lasts a long time), or fever may need chest x rays. The
test can help find the cause of these symptoms.
Chest x rays look for conditions such as pneumonia, heart failure,
lung cancer, lung tissue scarring, or
sarcoidosis. The test also is used
to check how well treatments for health problems are working.
People who test positive for tuberculosis (tu-ber-kyu-LO-sis) exposure on
skin tests, but have no symptoms, also may need chest x rays.
Sometimes, doctors order more chest x rays within hours, days, or months of
an earlier chest x ray. This allows them to follow up on a condition.
People who are having certain types of surgery also may need chest x rays. Doctors
often use this test before surgery to look at the structures inside the chest.
