The first 3 Teslas magnetic resonance imager for research

27.10.2006
The University Hospital at the University of Navarra and the Applied Medicine Research Centre (CIMA) of the University has recently acquired a 3 Teslas magnetic resonance imager for joint use, the first for research applications in Spain.

The 3 Teslas is the magnetic resonance imaging unit with the highest strength currently permitted by international medical bodies for the morphological study of the human body.

Enhanced precision

The University Hospital at the University of Navarra currently has two other magnetic resonance units. The first of these has a strength of 0.2 Teslas (unit of magnetic field) with a C-shape or “open” structure. Apart from this, the hospital also has a 1.5 Teslas unit of a cylindrical shape.

The fundamental difference between the resonance units is marked by the intensity of the main magnetic field. There currently exist imaging units that have strengths from 0.2 Teslas and others that are currently in an experimental phase and reach a strength of 7 Teslas.

The most notable advantage of the 3 Teslas unit is its high precision given that it enables the recording of an enhanced image quality in less exploration time. Moreover, the imaging unit will be used to continue lines of research in close collaboration with CIMA, the most important of which involve the study of Alzheimer’s Disease and Parkinson’s.

Specialist medical uses

At a health care level, the medical specialities to benefit most from the acquisition of this unit, and in which the use is the most novel, are neuro-radiology, imaging diagnosis in muscular-skeletal injuries and angiography by Magnetic Resonance. Besides, there exist other areas of the body the study of which will also be enhanced by the use of 3 Teslas resonance such as the abdomen, the breast and the heart, amongst others.

Likewise, the greater strength of the magnetic field enables the optimisation of highly specialised techniques such as, for example, diffusion (used, fundamentally, for the study of the brain), perfusion (blood circulation system) and functional magnetic resonance.

Molecular radiology

The 3 Teslas unit also provides new care possibilities as regards molecular radiology. The new concept of imaging procedures involves the use of substances that are deposited at a molecular level and the behaviour of which, observed using various techniques, enables us to make a diagnosis and to differentiate the various elements under study. For example, the early diagnostic search for a cancer prior to it reaching a certain size.

Side effects

Despite the overall innocuousness of the exploration and diagnostic technique, there are certain patients for which its use has side effects, basically those with pacemakers given that the magnetic fields render this heart apparatus inoperable. Any ferromagnetic metallic structures have to be carefully monitored before introducing a patient into a strong magnetic field, as the influence of the field may cause these metal structures to move or their temperature to rise.

Neuroimaging in Parkinson’s and Alzheimer

The acquisition of the 3 Teslas magnetic resonance imaging unit will enhance Functional Neuroimaging research – already initiated at the Applied Medicine Research Centre (CIMA) of the University.

A number of research projects into Parkinson’s disease focus on the role of the basal ganglia - altered with this condition - and the perception of tactile, auditory or visual stimuli. Within this line of research, one of the priority studies is related to the control of voluntary movement. For the patient with Parkinson’s, and using magnetic resonance, the areas of the brain that function while carrying out complex manual movements are identified and likewise how this cerebral activity is modified with learning. It is of interest to know the plasticity of these altered neuronal populations and how they react to and change with medication.

Another important line of research involves cognitive neurology, related to the onset of dementia. For example, in persons with memory or attention disorders, it can be determined if there exists incipient dementia or not. While undergoing resonance, the patient is given cognitive tasks of a simple nature and targeting a specific function, for example, attention, memory, orientation, discrimination, amongst others, with the aim of measuring the neuronal activity of the different parts of the patient’s brain while undertaking these cognitive tasks.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
