Pak Hospital X-rays are a type of electromagnetic radiation that can penetrate various materials, including the human body. The different types of X-rays used in medical imaging are categorized based on their specific applications and the areas of the body they are used to visualize. Here are some common types of medical X-rays:
- Plain X-rays (Radiography): This is the most common type of X-ray imaging. It involves taking pictures of bones and some soft tissues to diagnose fractures, joint dislocations, infections, and other conditions. Plain X-rays are used in various parts of the body, including the chest, abdomen, limbs, and spine.
- Fluoroscopy: This is a real-time X-ray technique that captures moving images of internal structures. Fluoroscopy is used to guide procedures such as barium studies (e.g., upper GI series, barium enema), joint injections, and cardiac catheterization.
- Computed Tomography (CT scan): CT scans use X-rays to create detailed cross-sectional images of the body. CT scans are particularly useful for diagnosing conditions in the brain, chest, abdomen, and pelvis. They provide more detailed information than conventional X-rays.
- Mammography: This is a specialized X-ray imaging technique used for screening and diagnosing breast cancer. Mammograms can detect breast abnormalities such as tumors, calcifications, and cysts.
- Bone Mineral Density (BMD) Testing: Also known as dual-energy X-ray absorptiometry (DEXA or DXA), this type of X-ray measures bone density and is used to diagnose osteoporosis and assess fracture risk.
- Dental X-rays (Intraoral and Extraoral): X-rays are commonly used in dentistry to visualize teeth, jawbones, and surrounding structures. Intraoral X-rays capture detailed images of individual teeth, while extraoral X-rays provide a broader view of the entire oral cavity.
Each type of X-ray serves specific diagnostic purposes and uses varying levels of radiation exposure. The choice of X-ray technique depends on the clinical question, the area of interest, and the specific information needed by the healthcare provider.
