Which of the following is used for detecting viable pregnancy?
Foetoscopy
Viable pregnancy is when signs that the foetus is alive can be detected. USG or an ultrasound scan is a medical test that uses high-frequency sound waves to capture live images from the inside of your body and can be used to capture live images of the foetus. Fetoscopy is an endoscopic procedure during pregnancy to view and allow access to the fetus, the amniotic cavity, the umbilical cord, and the fetal side of the placenta. USG and Foetoscopy can detect fetal heartbeat indicating life. Amniocentesis is a process in which amniotic fluid is sampled using a hollow needle inserted into the uterus, to screen for abnormalities in the developing fetus. And chorionic villi technique is a test made in early pregnancy to detect congenital abnormalities in the fetus, in which a tissue sample is taken from the villi of the chorion. Both amniocentesis and chorionic villi technique cannot distinguish between live or dead foetus.
