Definition - What does Sonogram mean?

A sonogram is the image produced during an ultrasound exam. The sonogram is a 2-D black and white visual, typically of a fetus during pregnancy. Ultrasound exams are noninvasive procedures standard to pregnancy and pose no risk to a developing fetus.

FertilitySmarts explains Sonogram

An ultrasound works by using sonograph technology to produce an image. There are two types of ultrasounds pregnant women experience:

Transvaginal ultrasound – a small probe transducer is inserted into the vagina. Used during the early stages of pregnancy.

Standard ultrasound – a transducer is placed over the abdomen.

Advanced ultrasounds use similar technology and procedures to create additional types of imagines, including 3-D or 4-D visuals. Ultrasounds are used during pregnancy to:

  • Verify conception
  • Confirm multiples pregnancy
  • Determine due date
  • Track development
  • Observe fetal movement
  • Detect certain abnormalities or conditions
