X-ray

X-ray or radiography uses a very small dose of ionizing radiation to produce pictures of the body’s internal structures.
X-rays are the oldest and most frequently used form of medical imaging.

They are often used to help diagnose fractured bones, or look for injury or infection.
Some X-ray exams may use an iodine-based contrast material or barium to help improve the visibility of specific organs, blood vessels, tissues or bone.
