MRI is a radiological diagnostic technique to visualize the anatomical structures of the area being evaluated. The physical basis has nothing to do with ionizing radiation, such as computed tomography (CT) / scanner or X-rays, but is based on the application of magnetic fields that alter the mobility of the particles that make up our cell . When applying these fields, these particles are stopped for a few microseconds and, when suspending the magnetic field, the mobility returns to these particles and produces an amount of energy that capture about resonance device detectors and, through a computer system , each quantity of energy reaching the receptors is applied to an intensity of black and white colors what we see on the MRI images when we deliver the photos of it.

The contrast is sometimes necessary to use in carrying out these resonances do not produce allergic and can be managed peacefully.

Another interesting aspect is that patients with metallic elements in your body, such as prostheses or pacemakers should notify the radiologist before performing any such test since the application of electromagnetic fields could lead to a malfunction of the same.

What limitations does this test?
One of the limitations of performing magnetic resonance until recently was the inability to biopsy or remove a lesion that was demonstrated by MRI, however, has appeared on the market the ability to perform biopsies lesions on MRI but, to date, are not available in all centers.

MRI is a technique with proven benefits in certain situations and that he will take rise in other indications are not so clear so far. The realization costly in both time and money does not become more widely used and constitutes another limitation.
