The mean gestational sac diameter (MSD), yolk sac and embryo crown rump length (CRL) were routinely measured at each visit. An intrauterine haematoma was diagnosed when a crescent-shaped hyperechoic or hypoechoic area between the chorionic membrane and myometrium was visualised. If present, it was measured in three orthogonal planes.

Flannelly GM et al (1976) found that a mean sac diameter of 20mm or more without a visible yolk sac, or a size of 25mm or more without a visible embryo, are major criteria for pregnancy failure with a 100% predictive value. Irregular gestational sac is associated with abnormal outcome in 100% of the cases.

The proposed method automatically segments the GS and calculates the Mean Sac Diameter (MSD) and other geometric features of the segmented sac. After classifying the image based on the extracted features into either a pregnancy of unknown viability (PUV) or a possible miscarriage case, we assign the decision with a strength level to reflect its ...

Mean sac size can be used to date an early pregnancy. A MEAN DIAMETER is calculated form three planar sections. MSD (mm) + 30 = gestational age (days) A (MSD – CRL) < 5mm is associated with a high risk of SAB. Crown-rum length (CRL) measured until the 12th gestational week. most accurate method of dating a pregnancy
Fetal Biometry and Growth | Radiology Key
The yolk sac has nutritive, endocrine, metabolic, immunologic, secretory, excretory and haemopoetic functions. The purpose of this study are to study the biometry of the yolk sac and its relation with menstrual age, crown rump length and mean gestational sac diameter in early pregnancy and to assess the predictive value of abnormal yolk sac size for abnormal pregnancy outcome.

Growth Assessment by Ultrasonic
The severity of the damage depends on the gestational age at which the damage occurs. Low birth weight and asphyxia are common risk factors for CP. Clinical manifestations include increased muscle tone, prolonged primitive reflexes, exaggerated deep tendon reflexes, clonus, rigidity of the extremities, scoliosis, and contractures.
