Magnetic resonance imaging
Written by:The Magnetic Resonance ( NMR ) is one of the most established in the diagnostic medical imaging, which allows us to study and get images of any part of the body techniques, noninvasively and safe, since method is not invasive and does not use any kind of radiation.
The technique involves the exposure of the organism to the action of a powerful magnetic field, which acts aligning the hydrogen atoms of different tissues in the direction of the magnetic field itself. The timely arrival of a radio-frequency wave makes these regain the original position to release energy and emitting a signal that is detected by the computer and converted into image.
During the study different sets of images are made. The duration of the test is variable according to the study area, the type of pathology and findings that will be encountered, but usually lasts between 20 and 45 minutes.
Directions
Magnetic resonance imaging allows to study many of the tissues and pathologies in the different structures of our body. We can divide the signs into four branches preference:
Cranial Resonance. includes the brain and all the structures contained in the skull and face tissue.
Resonance column. includes the study of the vertebrae, the spinal cord and adjacent structures.
Resonance osteo -articular and musculo- skeletal. includes bones, joints, musculo- ligamentous structures, vessels and peripheral nerves.
abdominal and pelvic scan. All the organs of abdominal cavity, biliary tract and gynecological studies.
To these it adds up other indications, some already established as true specialties such as: vascular scan cardiac magnetic resonance, the resonance breast or spectroscopy.
There are also other techniques that develop and are growing in importance, such as diffusion, perfusion of tissue and functional studies to increase in the very near future the indications and results of Resonance magnetic.
The teams
Creu Blanca has 3 open teams, and is the only private medical center Cataluna which has 3 teams of 3 Teslas. Creu Blanca , following the trend of the American market ( innovator and pioneer in the field of diagnosis by image ) and acquired a first resonance 3-Tesla in 2010, another in 2012 and the last in 2013.
Your computer has 3 Teslas means having twice the signal in a 1.5, so you can make the same studies but in half the time and with sharper image, what such equipment can detect much smaller lesions which can be detected on a smaller capacity.
Features of the resonances at 3 Tesla
Greater patient comfort. The equipment consists of a large amplitude that guarantees the patient more space, reducing the feeling of anxiety and claustrophobia.
Noise Reduction. To mitigate the noise of resonance, the patient is offered with headphones listening to music going to reduce the noise of the machine, well, now the technology has Vantage Titan&ldquo,&rdquo Pianissimo ;, a unique system that dramatically reduces acoustic noise inside and outside the scan room
.Reduction of acquisition time. Thanks to the technology acquisition SPEEDER can not only reduce the time of acquisition of the images, but also minimize the potential distortions.
