You may have heard about an MRI machine, but what is it? An MRI is a noninvasive diagnostic technique that allows a medical professional to see inside your body. The images are taken for a short period of time, and the entire process can take anywhere from a few seconds to a few minutes. An MRI can reveal valuable information about your internal organs and systems, and can help determine the cause of your ailment and the progress of your treatment.
An MRI machine resembles a donut with a hole in the center. You’ll lie on a table that slides into the donut-shaped opening. The table slides into the tube, and only the parts that are going to be scanned will be scanned. For a full body scan, the MRI machine has a large magnet surrounding it. Once you’ve arrived at the facility, you’ll be instructed to change into hospital gowns and remove any metal jewelry.
MRI machines do not use radiation. Instead, radio waves re-align hydrogen atoms within the body. They do not cause any changes in the tissue, and instead produce different signals based on their positions. Millions of protons are scanned at one time, and the information they provide can give doctors an incredibly detailed picture of what’s going on inside the body. While MRI scans are safe and painless, some people may feel anxious or claustrophobic during the procedure. In most cases, however, patients can cope with the discomfort with support from the radiographer.
The MRI machine has a variety of features, and a full understanding of its function is critical for effective treatment. The best way to prepare for an MRI is to read up on the procedure beforehand. Knowing what to expect in advance will make the process go more smoothly and will reduce the risk of complications. You should be aware of your doctor’s full form and ask as many questions as possible. This way, you’ll be better prepared to face the experience without fear.
MRI machines use radio waves, magnetism, and a computer to produce a detailed picture. A radiofrequency current stimulates protons in the body and forces them to align with the magnetic field. This strain causes them to release energy. The information captured by the computer is then translated into a two-dimensional image. It can take anywhere from 30 minutes to two hours to get a full image. So, what exactly is an MRI?
Open MRI machines are less claustrophobic than closed MRI machines. They also offer more room, so they are better suited for obese or claustrophobic patients. Patients may also want to use an open MRI machine. The open form is better suited for small children and patients with large shoulders. A claustrophobic patient may also want to opt for an open MRI, as this type of MRIs can be more comfortable for them.
