We use computers to create accurate a cross-sectional picture. Like one piece in a loaf of bread, this two-dimensional (2D) scan shows a “slice” of the inside of your body. The CT scan can reveal anatomic details of internal organs that cannot be seen in conventional X-rays. During a CT scan, you lie in a tunnel-like machine while the inside of the machine rotates and takes a series of X-rays from different angles. Why it's done
 

CT scan helps to the following issues
 

• Diagnose muscle and bone disorders, such as bone tumors and fractures

• Pinpoint the location of a tumor, infection or blood clot

• Guide procedures such as surgery, biopsy and radiation therapy

• Detect and monitor diseases and conditions such as cancer, heart disease, lung nodules and liver masses

• Monitor the effectiveness of certain treatments, such as cancer treatment

• Detect internal injuries and internal bleeding
