What Is an X-ray Used For?

They are often used to help diagnose fractured bones, look for injury or infection, and locate foreign objects in soft tissues. 

Some exams may use an iodine-based contrast material or barium to help improve the visibility of specific organs, blood vessels, tissues, or bones. 

X-rays can also guide doctors or surgeons during procedures. For example, X-rays can be used in coronary angioplasty to guide a catheter along the arteries.
