Movements such as fetal heart beat and malformations in the feus can be assessed and measurements can be made accurately on the images displayed on the screen.Such measurements form the cornerstone in the assessment of gestational age, size and growth in the fetus.In such cases, it is reasonable to repeat the ultrasound scan in 7-10 days to avoid any error.

Obstetric Ultrasound is the use of ultrasound scans in pregnancy.
Since its introduction in the late 1950s ultrasonography has become a very useful diagnostic tool in Obstetrics.
A short history of the development of ultrasound in pregnancy can be found in the History pages.
Ultrasound scan is currently considered to be a safe, non-invasive, accurate and cost-effective investigation in the fetus. The gestational sac can be visualized as early as four and a half weeks of gestation and the yolk sac at about five weeks.
A full bladder is often required for the procedure when abdominal scanning is done in early pregnency.
There may be some discomfort from pressure on the full bladder.
Repetitive arrays of ultrasound beams scan the fetus in thin slices and are reflected back onto the same transducer.
The information obtained from different reflections are recomposed back into a picture on the monitor screen (a sonogram, or ultrasonogram).
The diagnosis of missed abortion is usually made by serial ultrasound scans demonstrating lack of gestational development.Tags: Adult Dating, affair dating, sex dating
