When you visit the MRI clinic, you will first be given a gown and asked to take off any jewelry or metal objects. You will also be required to lay still on the table, where a lab assistant will help you position yourself in the most comfortable position. Once the table has been placed in the MRI machine, it will slide into the doughnut-shaped opening. The table slides into the MRI machine, and you will only be inside the machine for the parts of your body that need to be scanned.
A magnetic field is created inside the MRI machine. The first magnet causes water molecules to align in a certain direction. The second magnet turns on and off in a series of pulses to move hydrogen atoms into a new, more aligned state. A computer processes the signals and creates a cross-sectional image of the body. This image is then displayed on a viewing monitor. The MRI exam usually takes anywhere from thirty minutes to two hours.
A MRI scan can be scary for some patients, especially if you have a fear of the scanner. Although the scanner is equipped with a quiet setting, some patients may feel claustrophobic during the MRI process. If you’re worried about your own anxiety during the procedure, you should speak with the practitioner who requested the test. A mild sedative may be prescribed to calm you down. During the MRI, staff members will be nearby and can answer any questions you may have. If you feel uncomfortable during the scan, simply use a buzzer to alert the staff so they can help you.
MRI scans are painless, but the patient must remain still for the duration of the test. The scan can take up to an hour, but the patient must stay still during the entire time. During the scan, the technologist may ask basic questions and make small movements to get a clear image of the body. This process is often nerve-wracking for the patient, but is a valuable way to diagnose and treat diseases.
While many people feel nervous before undergoing an MRI, there’s nothing to worry about. By reading the full form of the MRI, you can make sure that your doctor will give you the best care. After all, you’re going to be spending a long time in the scanner and want to see what happens. You’ll be happy you read this article. You’ll be on your way to a more pain-free and stress-free MRI visit!
MRI machines use a radio-frequency coil to generate magnetic fields. Because the magnetic fields generate radio waves, the atoms of the human body absorb the energy emitted by the radio frequency coil. This energy is then captured by the MRI scanner and converted into an image. It’s the perfect method for studying neuronal organization, function, and chemistry. And because of its ease of use, MRI is the most widely used imaging method today.
