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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
