MRI Diagnostics: Criteria for selecting a toll center for magnetic resonance imaging


According to official data published in the press, in 2014, 20% more patients in Russia used paid medical services than a year earlier. It is no secret that many medical services can also be obtained through the compulsory medical insurance system, but the time you spend waiting can be counted in weeks. That is why many people choose paid medicine, and often this applies to checkups such as magnetic resonance imaging (MRI Vancouver). But how do you choose a diagnostic center when there is an abundance of supply on the market?

In our article we will tell you what to pay attention to when considering the services you are interested in various institutions.

MRI Diagnostics: Criteria for selecting a toll center for magnetic resonance imaging

Type of MRI-diagnostics

The first criterion, to which we should pay attention, is whether the list of services of the clinic includes “your” research. For example, not all clinics conduct MRI procedures for brain, heart, and blood vessels. If a clinic does not have the capacity to perform any examination, it may also indicate the quality of the equipment installed there, and the qualification of specialists. So, the type of diagnosis is the first criterion on which “screening” should be done.

Tomograph

Now that we’re talking about the quality of the technique, let’s talk a little more about how the MRI is arranged.
Many have seen what an MRI machine looks like – it looks like a cylinder, inside which there is a couch (or table) on which the patient lies during the procedure. The cylinder is actually a powerful magnet that affects a person. The hydrogen atoms in the human body send a response signal, which is recorded by the tomograph receiver. Then the whole set of received signals is processed by the computer and converted into an image, so the doctor sees it on the computer screen.

It’s an interesting fact

For quite a while, doctors used another name for a CT scanner, nuclear magnetic resonance. It accurately described the essence of the procedure, which resulted in detailed images of the organs. However, the word “nuclear” caused fear and negative impression, and then the name was replaced by the already familiar to us “magnetic resonance tomograph.
The first characteristic worth paying attention to is the power of the device. The power of the magnetic field is measured in tesla, and accordingly MRI tomographs happen:

  • 0.1 to 0.5 Tesla, low-field;
  • 0.5 to 1 Tesla, mid-field;
  • from 1 to 2 Tesla are high;
  • from 2 Tel – ultra-high ground.
    Obviously, the higher the power of the device, the greater its capabilities. In particular, high-end tomographs allow you to do almost all the research and reduce the time it takes to scan the body directly. The most powerful devices to date are ultra-high (3 Tl), but experts note that in the field of diagnosis, they have approximately the same capabilities as the high-end. Particularly powerful tomographs are often used as a base for scientific research.
    Thus, the “optimal” device is one with a capacity of 1.5 Tl and above. It can be used for examinations such as MRI of vessels, including observation of blood flow in dynamics, heart, brain, MRI (study of the molecular composition of brain tissue) or functional MRI, which allows to determine the location of functional areas of the brain.
