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
