3D-4D ultrasound of a fetus imaged with a GE Volusion E10 system. It shows the yoke sac.
Fetal yoke sac as seen on ultrasound at eight weeks. Imaged with a Philips Envisor system.
Zika virus infected fetus on ultrasound, showing calcifications in the brain and microcephaly.
Umbilical cord on fetal ultrasound, showing the venous and arterial blood flow using color Doppler. Imaged with a Philips Envisor system.
Fetal heart with Doppler heartbeat waveform, showing a normal cardiac evaluation.
Fetal heart on ultrasound at 30 weeks, showing a heart valve opening. Imaged with a Philips Envisor system.
Fetal ultrasound with subchorionic hemorrhage at seven weeks. Imaged with a Philips Envisor system.
Ultrasound imaging can identify the sex of the baby by imaging the groin area. The penis on the male fetus appears as what is commonly called the "turtle" sign, which resembles like a turtle poking its head out of its shell. This image shows a female fetus with the "hamburger" sign created by the labia of the vagina.
Fetal ultrasound image composite created during exams to screen for spina bifida.
Fetal ultrasound showing the face, skull of the fetus and the placenta (gray mass to left).
Fetal ultrasound showing image enhancement with the ContextVision US PLUSView image reconstruction software.
Baby face on 3-D ultrasound using Canon's Luminance lighting visualization for life-like fetal echo.
Fetus with hand in front of its face and umbilical cord seen using 3-D ultrasound. Images using Philips TrueVue imaging technology.
Fetal kidneys on ultrasound. The image shows a cross sectional slice of the abdomen. There is an acoustical shadow (dark area where the image drops out) caused by the spine in the center of the image. Sound waves have difficulty penetrating bone. Imaged with a Philips Envisor system.
Fetal abdomen at 30 weeks. Imaged with a Philips Envisor system.
Fetal four-chamber view of the heart.
Fetal umbilical cord showing Doppler blood flow. Imaged using GE Healthcare's Voluson E10 HDlive Flow feature.
A transvaginal ultrasound of a fetus at eight weeks. It shows the yoke sac and the umbilical cord. Imaged using a Philips HD15 system.
The placenta, the gray mass in the center of the image, as seen on a fetal ultrasound. The fetus is seen, partly out of plane, under and on either side of the placenta.
Fetal aortic arch as seen on ultrasound.
A fetal ultrasound with annotations to show the relation of body parts for those unfamiliar with baby ultrasound images.
A 3D fetal ultrasound showing twins. Imaged using a GE Healthcare E10 system.
A 3-D ultrasound of a baby rendered with advanced visualization software from Vizua.
Image of blood flow in the fetal abdomen. It shows the heart (large colored mass to the left) and the main arteries of the body connected to blood flow from the mother via the umbilical cord (right side of image). The fetus is being viewed from the side, with its neck on the left edge of the image, spine along the bottom and abdomen (gray area) in the center of the image. Imaged using Canon's Aplio 500 Advanced Dynamic Flow (ADF) feature, which displays true blood flow.
Fetal ultrasound software includes digital calipers sonographers use to measure between two points. There are a series of standard measurements taken that are used to determine the age of the fetus and estimate the date of birth. Most newer ultrasound systems automate this feature once the measuring points are determined by the sonographer, as seen in this example of on a Philips system. The software automatically calculated that a 7.03 cm long fetus is 13 weeks old.
Below is a collection of prenatal ultrasound pictures from the Imaging Technology News (ITN) archive. Use the arrows to click through the image gallery. It includes transvaginal ultrasound images and fetal echocardiogram images. Fetal imaging is referred to by many names, including pregnancy sonograms, pregnancy ultrasound, endovaginal ultrasound, obstetric ultrasound, OB ultrasound, baby ultrasound, prenatal ultrasound. Fetal heart ultrasound is also called baby echo or prenatal echo.
