X-Ray

Function

An X-ray (radiograph) is a non-invasive medical test that uses ionizing radiation to produce images of the inside of the body. Different tissues absorb different amounts of radiation; dense materials like bone appear white, while softer tissues like muscle or organs appear in shades of gray, and air-filled spaces (like lungs) appear black.

Why it is Ordered

X-rays are the first line of diagnostic imaging for a vast array of conditions:

• Skeletal Assessment: To detect fractures, dislocations, or degenerative bone diseases like osteoporosis and arthritis.
• Chest Evaluation: To diagnose pneumonia, lung cancer, or heart failure (by checking heart size).
• Abdominal Issues: To find swallowed objects or identify intestinal blockages.
• Dental Health: To visualize cavities or impacted wisdom teeth.
• Procedural Support: To ensure correct placement of catheters or orthopedic hardware.

Associated Conditions

• Fractures: Breaks or cracks in the bone.
• Infections: Such as pneumonia in the lungs or osteomyelitis in the bone.
• Tumors: Many types of bone and lung tumors are visible on X-ray.
• Scoliosis: Abnormal curvature of the spine.
