What Is a CT Scan? A Patient Guide

A CT scan—short for computed tomography—is a powerful medical imaging test that helps doctors see detailed pictures of the inside of your body. At Independent Physicians Medical Center (IPMC) in Northeast Philadelphia, we offer advanced CT imaging in a comfortable outpatient setting so you can get answers quickly without the stress of a hospital visit.

What Is a CT Scan?

A CT scan combines a series of X-ray images taken from different angles and uses a computer to create cross-sectional “slices” of your body. These detailed pictures show bones, soft tissues, blood vessels, and organs more clearly than a standard X-ray.

CT scans can be performed on many parts of the body, including:

  • Head or brain
  • Chest
  • Abdomen and pelvis
  • Spine
  • Joints
  • Heart and blood vessels

Because of the comprehensive detail they provide, CT scans are often used when a doctor needs clearer insights than a regular X-ray can offer.


Why Do Doctors Order CT Scans?

CT imaging serves many medical purposes. Your physician might recommend a CT scan to:

  • Diagnose injuries and bone fractures
  • Identify infections or internal bleeding
  • Locate tumors and evaluate cancers
  • Guide biopsies or other procedures
  • Monitor how well treatment is working
  • Assess blood vessels and organs in detail

Some specialized CT scans—such as coronary or abdominal scans—can even provide precise information about heart disease or abdominal conditions.


How a CT Scan Works

When you have a CT scan:

  1. You lie on a padded table that slides into a donut-shaped machine.
  2. The scanner rotates around your body, sending X-rays from different angles.
  3. A computer combines these X-rays into detailed cross-sectional images—sometimes even 3D views.
  4. A radiologist reviews the images and sends a report to your doctor.

The procedure is painless, typically quick, and does not require surgery.


What About Contrast Dye?

Some CT scans use contrast material—a dye given orally or through an IV—to highlight blood vessels, organs, or other structures more clearly. Contrast helps doctors see more detail, but it’s not always necessary.

Your technologist will explain whether contrast is needed and provide instructions ahead of time.


Is a CT Scan Safe?

CT scans use radiation to produce images. While the amount is higher than a standard X-ray, it is generally considered safe when medically justified and performed by trained professionals.

If you are pregnant or think you might be, be sure to let your doctor know before the scan.

Modern CT scanners use optimized protocols to keep radiation exposure as low as possible while still providing clear imaging.


What to Expect After Your CT Scan

Most people can resume normal activities right away. If you received contrast dye, your provider may suggest drinking extra water to help flush it out. Your physician will review the results and discuss them with you once they’re available.
