X-rays are high-energy radiations. An X-ray machine produces short bursts of X-rays which can easily pass through our body like fluids, soft tissues. However, dense tissue like bones will block some of the X-rays. Denser the tissues fewer X-rays pass through the body. An arthrogram is a test using X-rays to obtain a series of pictures of a joint after a contrast material (dye, water, air) has been injected into the joint. This allows the doctor to see the soft tissue structures of your joints. However, without contrast material cannot see these structures. A special type of X-ray, called fluoroscopy, is used to take pictures of the joint.
