What Are Ultrasounds: Purpose, Types, and Benefits

Imaging tests have gained immense popularity over the past decades as excellent tools for diagnostic purposes. Ultrasound is one such revolutionary technological innovation that helps healthcare professionals globally. It is a noninvasive test that works on sound wave energy. 

The ultrasound Buckhead specialists offer patients convenient and accurate imaging to diagnose health conditions and develop treatment plans. Let’s explore more about ultrasound, its purpose, and the procedure to perform the test. 

What are ultrasounds?

Ultrasounds produce images of your internal organs using a special transducer machine with a hand-held scanner or probe connected to a computer.  

The transducer emits high-frequency sound waves that penetrate through your skin, and as they reach your organs or tissues, they bounce off and return to the transducer. These transfer the information to the computer for conversion of soundwave data to high-quality imagery. 

What health conditions can be diagnosed through ultrasounds?

Ultrasounds are popularly used for diagnostic purposes to identify the cause of gynecological conditions.  

Common conditions diagnosed through ultrasounds include:

  • Abnormal vaginal bleeding
  • Heavy periods
  • Chronic pelvic pain
