4D ecography for the diagnosis of prenatal cardiopathy

14.10.2005


“4D ecography may well be a significant advance in the prenatal diagnosis of congenital cardiopathy”, explained Dr. Juan Luis Alcázar, specialist at the Obstetrics and Gynaecology Department of the University Hospital (University of Navarre).

One of the most recent novelties in ecographic studies has been the application of a fourth dimension, i.e. movement added to three-dimensional reconstruction. According to Dr. Alcázar, “the development of the STIC system, carrying out the spatio-temporal correlation of images, adds movement to 3D ecography. In this way, apart from obtaining exclusively anatomic information, structure from a functional perspective is evaluated”.

Foetal cardiopathy

One of the great advances of this technique is its application to the foetal heart. Concretely, the STIC system enables a 3D reconstruction of the foetal heart in real time and with movement. This procedure changes the approach to prenatal diagnosis of congenital cardiopathy. It is one of the most common congenital anomalies of the foetus, although to date it has been difficult to detect in pregnancy. The foetal heart is a very small organ that moves very fast (120 beats a minute) and thus, its anatomical study is complicated.

The spectrum of foetal cardiopathies is very wide, from asymptomatic lesions to malformations incompatible with life, needing specialised training. In this sense, knowledge of a foetal cardiopathy can change procedures during childbirth, such as attending a reference centre that guarantees immediate specialised attention. STIC provides important information that can increase the accuracy of the prenatal diagnosis of these pathologies. Apart from facilitating the detection of more lesions, this system enables a refining of the diagnosis and provides guidelines for early treatment.

Another application for the 7system being studied involves foetal movements. The Department of Gynaecology is working in conjunction with that of Neuropediatrics to establish movement patterns for foetuses of between 24 and 34 weeks. When a child of this gestational age is born and their movements studied, normally parameters for children of 40 weeks are applied; nevertheless, their neurological maturity is not the same and, thus, there exist doubts as to whether the patterns used are the correct ones.

Four dimensions’ technology enables the study of the foetus while it is within the maternal uterus and the visualisation of the movements of the limbs, facial gestures, and so on. These data enables the establishment of patterns more adjusted to their intrauterine neurological development for their subsequent postnatal examination.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
