What is ultrasound?

Ultrasound is a painless way to create images of organs and structures inside your body. The procedure uses a device called a transducer to send high-frequency sound waves into your body. 

The sound waves bounce off dense surfaces and travel back to the transducer. Then the transducer transmits the information to a computer that interprets the sound waves and produces an image of the structures.

Since ultrasound operates in real time, it can show movement in your organs, such as your heart beating. A special type of ultrasound, Doppler ultrasound, shows blood flow within organs and in blood vessels traveling from your heart through your body.  

When might I need an ultrasound?

Ultrasound imaging is best known for giving expectant parents the first view of their developing baby. However, it’s widely used to diagnose many health conditions because it provides detailed images of virtually every organ and structure in your body.

Dr. Vaca performs ultrasound to determine the cause of pain and other symptoms, assess disease in organs, and evaluate the extent of swelling and infection.

These are only a few examples showing why you might need an ultrasound:

  • Find and evaluate tumors
  • Detect narrowed blood vessels or changes in blood flow
  • Diagnose gallbladder disease
  • Examine small structures like the thyroid gland
  • Examine a breast lump
  • Assess joint inflammation
  • Evaluate bone disease

Dr. Vaca also performs in-office echocardiograms, which are ultrasounds used to diagnose heart disease and to assess damage after a heart attack.

How does ultrasound work?

Ultrasound is most often performed by placing the transducer against your skin above the targeted structures. Before this type of ultrasound, Dr. Vaca applies gel to your skin, creating a bond and enhancing sound-wave transmission through your skin.

Dr. Vaca may also perform your ultrasound procedure from inside your body. This technique produces clearer images because the sound waves don’t need to travel through skin. Examples of internal ultrasound include:

  • Transesophageal echocardiogram: The transducer is inserted into your esophagus to get images of your heart
  • Transrectal ultrasound: The transducer is inserted into the rectum to evaluate a man’s prostate
  • Transvaginal ultrasound: The transducer is inserted into the vagina to view a woman’s uterus and ovaries

Diagnostic ultrasound imaging is a safe procedure with no side effects. If you have questions or need to schedule a diagnostic ultrasound, call Carlos Vaca, MD, or book an appointment online.
