Some resources indicate that there are clear reasons for this and that such scans are also clearly beneficial because ultrasound enables clear clinical advantages for assessing the developing fetus in terms of morphology, bone shape, skeletal features, fetal heart function, volume evaluation, fetal lung maturity, [21] and general fetus well being.
Cephalic index viewed from above the head. The cephalic index or cranial index is a number obtained by taking the maximum width (biparietal diameter or BPD, side to side) of the head of an organism, multiplying it by 100 and then dividing it by their maximum length (occipitofrontal diameter or OFD, front to back).
Dolichocephaly (derived from the Ancient Greek δολιχός 'long' and κεφαλή 'head') is a term used to describe a head that is longer than average relative to its width. In humans, scaphocephaly is a form of dolichocephaly. Dolichocephalic dogs (such as the Lurcher or German Shepherd) have elongated noses.
A synonymous term is 'dolichocephaly' (the prefix 'dolicho-' means elongated). [9] Premature sagittal suture closure restricts growth in a perpendicular plane, thus the head will not grow sideways and will remain narrow. [10] [11] This is best seen in a view standing above the child looking downward at the top of the head. [12]
Ultrasound image of the foetus at 12 weeks of pregnancy in a sagittal scan. Measurements of fetal Crown Rump Length (CRL). The embryo and fetus float in the amniotic fluid inside the uterus of the mother usually in a curved posture resembling the letter C. The measurement can actually vary slightly if the fetus is temporarily stretching ...
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
Facial deformities with Smith-Fineman-Myers syndrome. SFMS affects the skeletal and nervous system. This syndrome's external signs would be an unusual facial appearance with their heads being slightly smaller than average, a narrow face (clinically known as dolichocephaly), a large mouth with a drooping lower lip that is held open, protruding upper jaw, widely spaced upper front teeth, an ...
Fetuses with the condition typically have a hypoplastic iliac bone which resembles a snail, short ribs, short neck, shortened and widened (dysplastic) fibula bones, premature ossification of the tarsus, shortened and broadened long bones which resemble a dumbbell, hypoplastia and flattening vertebrae, macrocephaly, dolichocephaly, toenail hypoplasia, flattening of the malar prominence, and ...
