Most often used during the early stages of pregnancy.Standard Ultrasound – Traditional ultrasound exam which uses a transducer over the abdomen to generate 2-D images of the developing fetus .The basic obstetric ultrasound examination provides an accurate and safe clinical assessment of the gravid uterus throughout a woman’s pregnancy including characterizing pregnancy location, identifying the number of embryos present, and aiding in the prenatal diagnosis of fetal anomalies.In 2013, the American Institute of Ultrasound in Medicine (AIUM), in conjunction with the American College of Radiology (ACR) and the American College of Obstetricians and Gynecologists (ACOG), released updated Practice Guidelines for Performance of Obstetric Ultrasound Examinations.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.
More and more women are getting ultrasounds very early in pregnancy.
In circumstances where both approaches are readily available, the greater detail provided by transvaginal scans usually outweighs other considerations, and is preferred.
The patient is scanned in the normal examination position (dorsal lithotomy) with her feet secure in stirrups and her perineum even with the end of the examination table.
It can be measured from the cervix to the fundus, AP diameter, and width.
Normal uterine volume is less than 100 cc (nulliparous patients) and less than 125 cc (multiparous patients).
Place a small amount of ultrasonic coupling gel on the tip of the transvaginal transducer. After lubricating the vaginal opening, gently insert the transducer into the vagina.
