Making sense of medical imaging

Medical imaging includes several different technologies, each designed to provide a specific type of information.

Understanding the basics can make it easier to know why a particular examination has been recommended and what you can expect.

X-ray

X-rays use a small amount of radiation to create images of structures inside the body. They are commonly used to examine bones and can also help evaluate certain areas of the chest and other parts of the body.

CT scan

Computed tomography, commonly called CT, combines multiple X-ray images to create detailed cross-sectional views of the body.

CT can provide detailed information about bones, organs, blood vessels, and other structures.

MRI

Magnetic resonance imaging uses a magnetic field and radio waves to produce detailed images of soft tissues and other structures.

MRI does not use ionizing radiation and may be recommended for areas such as the brain, spine, joints, and soft tissues.

Ultrasound

Ultrasound uses sound waves to create images of structures inside the body.

It is commonly used for abdominal, pelvic, vascular, and pregnancy-related examinations, among other applications.

Mammography

Mammography uses specialized X-ray imaging to examine breast tissue. It may be used for screening or to evaluate a specific breast concern.

Why the type of imaging matters

Different imaging technologies provide different types of information. Your provider chooses an examination based on the clinical question they need answered.

The goal is to use the appropriate imaging method for your individual situation.
