The standard representation is brighter color for higher echogenicity, giving the almost anechoic fluid an almost black appearance. Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing ...
A lithopedion (also spelled lithopaedion or lithopædion; from Ancient Greek: λίθος "stone" and Ancient Greek: παιδίον "small child, infant"), or stone baby, is a rare phenomenon which occurs most commonly when a fetus dies during an abdominal pregnancy, [1] is too large to be reabsorbed by the body, and calcifies on the outside as ...
Isoechoic – the same echogenicity as another tissue; Transvaginal ultrasonography – Ultrasound is performed through the vagina; Transabdominal ultrasonography – Ultrasound is performed across the abdominal wall or through the abdominal cavity; In normal state, each body tissue type, such as liver, spleen or kidney, has a unique ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
When an echogenic intracardiac focus is identified in an otherwise normal second trimester fetus, a normal cell-free DNA test can be very reassuring and obviate the need for invasive testing. Amniocentesis is a test to check a baby's chromosomes. A small amount of amniotic fluid, which contains some fetal cells, is removed and tested.
The gestational sac is spherical in shape, and is usually located in the upper part (fundus) of the uterus.By approximately nine weeks of gestational age, due to folding of the trilaminar germ disc, the amniotic sac expands and occupy the majority of the volume of the gestational sac, eventually reducing the extraembryonic coelom (the gestational sac or the chorionic cavity) to a thin layer ...

The incidence of the cysts in women younger than 35 was 1% (n=1017). The study found no cases of trisomy 18 in fetuses with cysts whose mother was younger than 35. The study concluded that "there is no evidence that detection of isolated choroid plexus cyst in women who are <35 years of age increases the risk of trisomy 18". [10]
