An ultrasound is a procedure that uses high frequency sound waves to scan the pelvic cavity and abdomen of a woman, and then creates a sonogram (a picture) of the placenta and the baby.
An ultrasound is a procedure that uses high frequency sound waves to scan the pelvic cavity and abdomen of a woman, and then creates a sonogram (a picture) of the placenta and the baby. The terms sonogram and ultrasound are technically very different. However, the two are used interchangeably.  An ultrasound examination, also known as ultrasonography, is a non-invasive imaging technique that allows internal body structures to be seen by recording echoes or reflections of ultrasonic waves. Unlike x-rays, which are potentially dangerous, ultrasound waves are considered to be safe.  A pelvic ultrasound uses sound waves to make a picture of the organs and structures in the lower belly (pelvis). A pelvic ultrasound looks at the bladder and: 1  The ovaries, uterus, cervix, and fallopian tubes of a woman (female organs). 2  The prostate gland and seminal vesicles of a man (male organs). For men and women, pelvic ultrasound may be done to: 1  Find the cause of blood in the urine (hematuria). 2  An ultrasound of the kidneys may also be done. 3  Find the cause of urinary problems. Ultrasound: Sonogram. An ultrasound exam is a procedure that uses high-frequency sound waves to scan a woman’s abdomen and pelvic cavity, creating a picture (sonogram) of the baby and placenta. Although the terms ultrasound and sonogram are technically different, they are used interchangeably and reference the same exam.

The technology is similar to that used by sonar and radar, which help the military detect planes and ships. An ultrasound allows your doctor to see problems with organs, vessels, and tissues—without needing to make an incision.

Your first ultrasound will typically be done between 18 and 20 weeks, but you may have one before 12 weeks to confirm your due date.  During this ultrasound, the doctor will confirm that the placenta is healthy and that your baby is growing properly in the uterus. The baby's heartbeat and movement of its body, arms and legs can also be seen on the ultrasound. If you wish to know the gender of your baby, it can usually be determined by 20 weeks.
