“…Increased yolk sac diameter, as shown in our data, is not an uncommon finding in missed abortions, as it is reportedly detectable in about one-fifth of such cases [22]. The yolk sac is the primary hemopoetic organ and may reflect deficits in involved mechanisms in embryos with trisomy 21, whereas trisomy 13 and 18 seem not to present with markedly enlarged yolk sac dimensions in sonographic assessment [21,23]. Cranio-facial clefts can be detected from the 8th embryonic week onwards.…”

“…As a result of the cessation of the embryonic/fetal heartbeat, 2 D sonographic presentability of the inner organs and their margins is considered to be impossible due to increasing tissue homogeneity. On the other hand, 3 D surface evaluation is possible in embryonic death and allows a direct and meaningful assessment and comparison with embryos showing normal development [6,20,21]. Results from those studies may have a valuable impact on our knowledge of the possible reasons for early pregnancy loss.…”

“…3D-ultrasound is also particularly useful in that the saved images allow diagnostic deliberation by the sonographer even after the examination ends and the patient is unavailable for further testing. Recently published studies have verified the utility of 3D-ultrasound in various diagnostic areas, including fetal biometry, skeletal dysplasia, facial anomaly, and fetal echocardiography [ 1 2 3 4 5 ]. However, 3D-ultrasound also requires the manipulation of 3D volume data to reconstruct the images, which requires time and effort.…”

ObjectiveTo evaluate the feasibility of five-dimensional Long Bone (5D LB), a new technique that automatically archives, reconstructs images, and measures lengths of fetal long bones, to assess whether the direction of volume sweep influences fetal long bone measurements in three-dimensional (3D) ultrasound and 5D LB, and to compare measurements of fetal long bone lengths obtained with 5D LB and those obtained with conventional two-dimensional (2D) and manual 3D techniques.MethodsThis prospective study included 39 singleton pregnancies at 26+0 to 32+0 weeks of gestation. Multiple pregnancies, fetuses with multiple congenital anomalies, and mothers with underlying medical diseases were excluded. Fetal long bones of the lower extremities-the femur, tibia, and fibula were measured by 2D and 3D ultrasound, and 5D LB, by an expert and non-expert examiner. First, we analyzed the 3D ultrasound and 5D LB data according to 2 different sweeping angles. We analyzed intra- and inter-observer variability and agreement between ultrasound techniques. Paired t-test, interclass correlation coefficient, and Bland-Altman plot and Passing-Bablok regression were used for statistical analysis.ResultsThere was no statistical difference between long bone measurements analyzed according to 2 different volume-sweeping angles by 3D ultrasound and 5D LB. Intra- and inter-observer variability were not significantly different among all 3 ultrasound techniques. Comparing 2D ultrasound and 5D LB, the interclass correlation coefficient for femur, tibia, and fibula was 0.91, 0.92, and 0.89, respectively.Conclusion5D LB is reproducible and comparable with conventional 2D and 3D ultrasound techniques for fetal long bone measurement.

“…In the fetuses with spina bifida the fourth ventricle space was compressed and no could be seen, we can also be used for early detection of open spina bifida. 24 Pending clinical confirmations is important to be able, during a 11 to 14 week scan, to detect these markers that can be considered as an alarm bell to identifying cases at risk assessment of intracranial translucency (IT) in the detection of spina bifida at the 11 to 13-week scan.

It is now widely considered that three-and four-dimensional (3-4D), namely 3D with a fourth dimension, time, offer too many possibilities to be ignored. Acquisition of a volume or region of interest is the great novelty of 3D technique. And just as exciting is the possibility of studying it in movement during ultrasound examination or afterward; also by other operators in an infinite number of section planes that can all be perfectly reproduced.This paper aims to provide pictorial documentation of pregnancy monitoring with 3D images, sometimes with the corresponding 2D image, so readers can begin to habituate themselves and hopefully acquire a different and personal key to the 3D image.

3D Ultrasound in Fetal Spina Bifida

Abstract: 3D ultrasound can be used to study the fetal spine, but skeletal mode can be inconclusive for the diagnosis of fetal spina bifida. We illustrate a diagnostic approach using 2D and 3D ultrasound and indicate possible pitfalls.
