Angina may feel like pressure or squeezing in your chest. The pain also can occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion. Angina isn't a disease; it's a symptom of an underlying heart problem.
Uses of X-rays. The main use of X-rays is in medicine. A comman application is in the form of X-ray machines, which take photos of a patientâs body. If an arm or leg were broken for example, then this limb would be put in front of the X-ray with a piece of photographic film behind.
Alternate methods of direct arthrography examinations may also use magnetic resonance imaging (MRI) or computed tomography (CT) following contrast material injection into the joint. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Direct arthrography is particularly effective for detecting disease of the structures within the joints such as ligaments, tendons and cartilage. 2  This is particularly true for the shoulder in the setting of shoulder dislocation and in the hip, wrist and elbow.
