Abstract

Summary: One of the most important objectives of ultrasonographic fetal biometry is the accurate gestational age (GA) estimation. The crown – rump length greater than 10mm has the best correlation with GA at 8–12 gestational weeks. GA could be estimated at 5–7 gestational weeks, measuring the dimensions of the gestational sack. Biparietal diameter is the main parameter that can me measured in the second trimester for GA estimation, but fetal head circumference can be used as well applying the “ellipse” function. However, when fetal head appears to be dolichocephalic or brachicephalic, femur length could be additionally used for GA estimation. At the third trimester of pregnancy, GA estimation could be improved when measuring the length of fetal kidneys. The main failures of GA estimation occur due to the application of fetal abdominal parameters or rather out of date and adjusted for an inappropriate population standards. Key words: gestational age, ultrasonographic fetal biometry.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
