Automatic Gestational Age Estimation Based on Crown Rump Length and Gestational Sac
The development of ultrasound technology allows us to see the structure and development of the fetus directly. Crown-Rump Length (CRL) and mean diameter of gestational sac (MSD) can be used to determine the age of the fetus. Both parameters are useful for measuring different aspects of the first trimester of pregnancy. This study proposes a method to obtain those parameter values automatically ...
متن کاملEstimation of gestational age in early pregnancy from crown-rump length when gestational age range is truncated: the case study of the INTERGROWTH-21st Project
BACKGROUND Fetal ultrasound scanning is considered vital for routine antenatal care with first trimester scans recommended for accurate estimation of gestational age (GA). A reliable estimate of gestational age is key information underpinning clinical care and allows estimation of expected date of delivery. Fetal crown-rump length (CRL) is recommended over last menstrual period for estimating G...
متن کاملStandardisation of crown-rump length measurement.
Correct estimation of gestational age is essential for any study of ultrasound biometry and for everyday clinical practice. However, inconsistency in pregnancy dating may occur through differences in measurement methods or errors during measurement. In the INTERGROWTH-21(st) Project, pregnancies are dated by the last menstrual period, provided that it is certain and associated with a regular me...
متن کاملNuchal translucency in normal fetus and its variation with increasing crown rump length (CRL) and gestational age.
BACKGROUND Nuchal translucency (NT) is the fluid collection behind the fetal neck which can be measured by ultrasound at 11-14 weeks of gestation. Increase in the nuchal translucency thickness is associated with various congenital anomalies. OBJECTIVE To study the relationship between nuchal translucency thickness, crown rump length and gestational age in normal fetus. METHODS Prospective a...
متن کاملUltrasonographic fetal scapular length measurement for assessment of gestational age
one of the major goals of antenatal care is estimation of gestational age.the most widely used parameters for evaluation of fetal growth are biparietal diameter (BPD),femoral length (FL) and adbominal circumference (AC).to determine the value of prenatal ultrasonographic scapula measurements for fetal growth and gesattional age a prospective ultrasonographic cross-sectional study was conducted ...
