In order to fully understand the meaning of the term imaging that concerns us now, it is necessary that its etymological origin be established previously. In this sense, we have to expose that it emanates from Latin and Greek, since it is composed of these two elements: the Latin noun “imago”, which can be translated as “portrait”, and the Greek word “lodge”, which is equivalent to "study of".
Imaging It is a term that is not part of dictionary of the Royal Spanish Academy (RAE) . The concept is used to name the set of techniques and procedures that allow to obtain images of the human body for clinical or scientific purposes.
The imaging or medical image , therefore, is used to reveal, diagnose and examine diseases or to study the anatomy and functions of the body . Radiology, medical thermography, endoscopy, microscopy and medical photography are part of these techniques. Other procedures that allow obtaining data that can be represented as maps or schemes (as the electroencephalography ) can also be included in the imaging.
The great advantage of imaging is that it allows to obtain internal images of the body No need to open it. The tomography For example, it is a single-plane imaging method that is carried out by moving an X-ray tube over the patient.
So important is the imaging technology and all the techniques that integrate it that currently exist in the world from university careers to degrees, with the clear objective that those who wish to specialize and train in this area in order to be qualified and highly competent professionals .
In this sense, people who are encouraged to carry out any of these educational proposals should study issues such as anatomy, cell biology, radiological techniques, neurobiology, scientific work, image processing system, scientific methodology, public health or radiological physics , among other.
The picture of magnetic resonance , on the other hand, appeals to the use of magnets to polarize hydrogen nuclei in water molecules of tissues. That excitation generated by the magnets in the hydrogen nuclei can be captured and coded spatially to generate images of the body.
Each of the images taken by magnetic resonance is called cuts and they have the particularity that they can either be stored and viewed on a computer or be printed. The skull, abdomen, spine or heart are the parts of the body that usually undergo this type of test that is usually characterized by these hallmarks:
• It is completely painless.
• It is necessary for the patient to be relaxed and not move, since doing so will cause the images to be blurred.
• Does not require recovery time.
The fluoroscopy It is an imaging technique that generates images in real time from a constant input of X-rays. Thanks to contrast media (such as iodine), it is possible to visualize how internal organs work.
The projection x-ray , the nuclear medicine and the ultrasound They are other imaging techniques.
