What is MRI?

If you have been injured in an accident, the most important task you have is to seek immediate doctor. After his wounds were treated and his condition was diagnosed as may be prescribed by your doctor for more tests. A test you can order called magnetic resonance imaging (MRI). It is a noninvasive way to obtain images inside body. Unlike X-rays and computed tomography (CT), it uses radiation, MRI uses magnets and radio waves. The MRI scanner contains a magnet. The magnetic field produced by an MRI is about 10 thousand times that of Earth.

This is done by the magnetic field of hydrogen atoms strength in the body to align a certain way, in the same way that the needle moves when you hold the needle near a magnet. When radio waves are sent toward the hydrogen atoms in line, it will be cured. A computer then records the signal. Different signals are sent by different tissues. The signal from normal tissues is slightly different from the signal sent by the cancerous tissue.

MRI images are called slices alone and these reductions can be stored on a computer or printed on film. The width of the section may affect the quality of the image produced. You can have an MRI performed through clothing. However, because the magnet is very, very strong, certain types of metals can cause significant errors, called artifacts in images.

The accuracy of magnetic resonance can be certified as stupid as we are led to believe. An MRI reading may indicate that there is a problem, MRI negative, but in reality it is a problem not detected. MRI has been considered a very effective way to obtain information about internal problems in the body. Were used for years as evidence of injury from a car accident. The most common injury in a car crash has found a bulge or a herniated disc.

One man said he had an MRI after a fall and the investigation did not reveal, except for bulging discs. He said the bulging discs were normal. He was ordered to do the exercises of the neck. Follow the exercise regime and possibly felt better. A year later he fell again and suffered the same symptoms, but have been more painful and debilitating. The symptoms do not diminish when he had another MRI showed a pinched nerve that has been diagnosed severe enough to cause paralysis if it does not suffer surgery open four to five vertebrae and pinched nerves without.

There are many explanations of why these explorations can be various outcomes. MRI are performed by radiology centers, which then send reports to doctors. Doctors can never be that if the MRI was well done, well done or if you use the machine is the most recent available. In addition, the form that were analyzed can affect the results. If the width of the image is too large slice may be difficult to read. Some companies even have a full spine MRI if a cervical, thoracic or lumbar MRI is ordered. The differences between the slices. This reduces the time needed to complete the examination, but also creates uncertainty because there no pictures of lakes. If the herniated disc is a part of the difference image would not have it. The idea is that the reduction on MRI can be programmed the time required for each MRI. This will result in inaccurate reselts and higher profits for the laboratory test.
