X-ray Scan

X-ray imaging is a widely used diagnostic tool that employs controlled radiation to produce images of the inside of the body, particularly bones and certain tissues. It is a quick, non-invasive procedure that helps doctors diagnose fractures, infections, and various medical conditions.

X-rays are among the most common and effective imaging techniques due to their speed, availability, and ability to provide clear images of the skeletal system and some soft tissues.

Uses of X-ray

X-rays are commonly used to:

• Detect bone fractures and dislocations
• Diagnose infections like pneumonia
• Identify dental issues
• Evaluate joint problems such as arthritis
• Locate foreign objects inside the body
• Monitor lung and chest conditions
• Guide certain medical procedures

Types of X-rays

• Chest X-ray — lungs, heart, chest wall
• Bone X-ray — fractures, dislocations
• Dental X-ray — teeth and jaw
• Spine X-ray — vertebrae and spinal alignment
• Joint X-ray — arthritis, joint injuries

Preparation for an X-ray Scan

X-ray scans generally require minimal preparation:

• Clothing: Wear loose, comfortable clothing. You may need to remove jewelry, belts, or any metal objects that could interfere with the image.
• Pregnancy: Always inform the technician if you are pregnant or suspect pregnancy, as X-rays involve radiation exposure.
• Medical history: Inform the technician about any recent X-rays or medical conditions.
