Sonogram vs Ultrasound

The difference between Sonogram and Ultrasound

The word Sonogram vs Ultrasound is commonly used for the same thing. There is a difference between them:

  • An Ultrasound is a tool to take pictures.
  • A sonogram refers to an image generated Ultrasound.
  • Sonography refers to the use of an ultrasound instrument for diagnostic purposes.

In other words, an ultrasound is a method, and the Sonogram is the end product.


Sonogram or Sonography is a painless and non-invasive procedure. It utilizes high-frequency sound waves, also known as ultrasound waves. It’s used to produce images of soft tissues, organs, blood vessels, and the flow of blood within the body. These images are used for medical research.

After the x-ray examinations, equally important, Ultrasound is the most common and widely used method of diagnosing images. It also allows doctors to gain insight into the inner workings of the body, like a Sonogram. To conclude, below mentions:

  • Secure
  • Radiation free
  • non-invasive
  • portable
  • Accessible to everyone
  • Affordable

Below are the difference between Sonogram vs Ultrasound


A sonogram, also known as an ultrasonogram. It is the visual image generate during the ultrasound examination.


A sonogram refers to a medically trained person to diagnose Ultrasound based technology. They provide doctors with detailed images of what’s happening inside the bodies of patients.

How does Ultrasound work?

In a word, Ultrasounds use high-frequency sound waves, which are absorbed into the body, and bounce (echo) off tissues and organs. Echoes create electrical signals, which are then translated by computers to create pictures of the organs and tissues after ultrasound and Sonogram definition here is the variations of Ultrasound. 

The variations of Ultrasound are:

  • Doppler Ultrasound is used to observe blood flow into the blood vessels and in the heart.
  • Elastography is used to distinguish cancerous tissue from healthy tissue.
  • Bone sonography is used to measure bone density.
  • Therapeutic Ultrasound is used to warm or break down tissues.
  • High intensity concentrated Ultrasound (HIFU) is used to remove or modify abnormal tissue of the body without open the skin.

Similarly, most ultrasounds are done with a transducer beside a Sonogram. The transducer place on the skin’s surface for the inside image. In addition, a more accurate diagnosis image is created through the introduction of an ultrasound transducer. Transducer specifically designed to insert into the body.

  • The transvaginal Ultrasound makes use of the transducer wand put in the vagina of a woman to obtain photographs of her uterus as well as Ovaries.
  • Transrectal ultrasound is often used to diagnose prostate problems. 
  • An echocardiogram of the transesophageal region utilizes a transducer probe inside the oesophagus for pictures of your heart.

Does ultrasound use?

However, in confirming the pregnancy, Ultrasound is most commonly used by doctors rather than Sonograms.


Doctor’s identify the condition of the soft tissues and organs of the body through Ultrasound images, not Sonogram images. After that, here is the list of different types of diagnoses referred to Ultrasound.

  • abdomen
  • Liver
  • kidneys
  • Heart
  • blood vessels
  • gallbladder
  • Spleen
  • pancreas
  • thyroid
  • bladder
  • breast
  • Ovaries
  • testicles
  • eyes

In addition, sound waves cannot be transmitted well through the areas that could hold air or gas (such as the intestines) or in the regions that are which are blocked by dense bone. Of course, above said procedures have some limitations to diagnosis with ultrasounds.

Procedures for medical use

If a doctor has the removal of tissue in a specific area of the body, for example, a needle biopsy ultrasound imaging may help in vision direction.

Therapeutic applications

Ultrasound is used for the diagnosis and treatment of specific soft tissue’s injuries.

Conclusion about Sonogram vs Ultrasound

Finally, Ultrasound refers to the process of using sound waves to produce images inside the body. Sonograms are the images produced from an ultrasound examination.

To summarize, Ultrasound refers to a safe and inexpensive imaging technology that assists a doctor to assess organs and soft tissues in the body.
