CT Scan

What is a CT Scan?
A Computed Tomography (CT) scan, also known as a CAT scan, is an advanced imaging technique that uses X-rays and computer processing to create detailed cross-sectional images of the body. This method provides more comprehensive views than traditional X-rays, making it invaluable for diagnosing a wide range of medical conditions. CT scans are particularly effective for visualizing bones, organs, and soft tissues.

Uses: Commonly used to assess conditions such as fractures, spinal stenosis, and tumors.
Benefits: Provides detailed views of the spine, aiding in the diagnosis of back pain and neurological issues.

7. CT Angiography (CTA)
Description: CT angiography is a specialized CT scan that focuses on blood vessels using a contrast dye.
Uses: It is used to evaluate vascular conditions, such as aneurysms, blockages, and vascular malformations.
Benefits: Provides high-resolution images of blood vessels, aiding in diagnosis and treatment planning.

8. CT Scan of the Extremities
Description: This CT scan targets the arms and legs, providing images of bones and soft tissues.
Uses: Useful for diagnosing fractures, tumors, and other injuries in the extremities.
