What Is a Diagnostic Medical Sonographer?

A diagnostic medical sonographer (DMS), generally referred to simply as a sonographer or ultrasound technologist, uses imaging equipment and soundwaves to provide doctors with internal images that help them make a diagnosis and prescribe treatment for their patients.

It is a non-invasive way to visualize internal organs when a physician needs to see what is going on inside the body. It is often the first imaging test that is performed after a disease is suspected or detected.

Sonographers are needed for a variety of healthcare issues, including:

  • Cancer screenings
  • Heart health
  • Organ health
  • Prenatal care
  • Infant care
  • Reproductive health care for both men and women

How Do You Become a Diagnostic Medical Sonographer?

Are you a problem-solver with good communication skills? Do you love working directly with people who may be in pain and confused about their medical condition?

Are you detail-oriented and can follow precise instructions to obtain the images needed to diagnose and treat patients? If so, according to the Bureau of Labor Statistics (BLS) being a diagnostic medical sonographer may be a great fit for you.

Becoming a diagnostic medical sonographer requires an associate degree from a qualified accredited school and most employers also require professional certification.
