MRIs, or rather Magnetic Resonance Imaging, are a very important advancement in the field of medicine, and detection. If you have ever had a head injury, unidentified pain, or some other hard to diagnose issue, your doctor may have ordered an MRI.

These advanced machines are extremely effective in finding inner issues or problems which a doctor may not be able to diagnose without opening you up on the surgical table. To better understand these complex medical machines, we should first understand how they work.

These machines first came on the scene in 1973, though the first images of humans weren’t published until 1977. As you can see, in the medical world, this technology could still be considered new.

How they work is both complex and simple at the same time. As we know, our bodies are largely composed of water.

Each water molecule in our body holds two protons. When the powerful magnetic field of the scanner is activated, the magnetism aligns these protons with the direction of the field.

The photons produced by the electromagnetic field produce a high frequency, which flips the spin of the aligned protons within the body. When the field is shut down, the energy from the two states is released in the form of a photon, which allows the use of magnetic resonance for imaging.

These images, when put in a sequence, can take very detailed images of both the soft tissues of the body, as well as the contrast of the bone, muscle, organs, etc. A medical dye can even be injected which will help to enhance the appearance of blood vessels, tumors, and inflammation.

Thus, if doctors are looking prescription cialis generic for cancer, checking out a concussion, or exploring a tear in the muscle, these impressive machines can meet all of your needs, and quite effectively. You may be wondering if these machines come at the cost of a risk to the patient.

This is not so-that is one of the draws of this technology. While it does emit a certain amount of radiation, it is less than that of a common x-ray.

The radiation it emits is non-ionizing, compared to CT scans and x-rays which operate with ionizing radiation. This is a great benefit for someone who has to have multiple scans, such as someone trying to discover if they have a tumor.

A typical MRI consists of about fifteen to twenty images, and takes around an hour to complete. The patient wears nothing but a hospital gown, and must remove all metal-earrings, hair pins, jewelry, etc.

The patient then lies down on a thin, plastic platform, which backs into the imaging machine. Those with a fear of small spaces might struggle with this setup.

The average machine rests quite low above the face, about four to five inches away. If you can close your eyes and just relax, you can often convince yourself you are merely napping, and not in such a tight contraption.

However, if this simply will not work for you, there is special, open equipment designed for those suffering with claustrophobia. They come up much wider above the face, and tend to be more comfortable.

The patient is given a set of ear plugs, as the sound of the imaging can be quite loud for some reason. There is a knocking and banging sound which can be quite annoying if your ears are not properly covered.

With the earplugs in place, it is much less obtrusive. The imaging technician will speak to you through the use of an intercom, which you can hear even through the earplugs.

They may tell you that this sequence will be only two minutes, and to be careful not to move. If you become panicky or uncomfortable at all, you can alert them immediately and they will come into the room.

With Kamagra these conveniences, this makes the whole process very comfortable, and safe. If you are the kind that can nap easily, this can even be a quite relaxing place to take a little snooze-just be careful not to move!

After the scan is completed, the images are read by the trained technician, and the results and images are sent to your ordering doctor or surgeon. At this point, they can talk to you about the different options you have, and they can even show you the images themselves.

While doctors are still learning more about these complex machines, they are a wonderfully safe and accurate way to prevent serious problems. Modern technology is truly an amazing thing.
