An MRI is a medical imaging procedure that manipulates the magnetic positions in the body using radio waves. The doctor will use an antenna to detect radio waves and then send them to the computer for analysis. These radio waves are converted into 3-D images of what is being scanned. These images can be used for diagnosing problems in the heart, brain, or brain stem.
You must remove all metal from your body before you have an MRI. Your belt, earrings, and buttons on your pants and shirts can all interfere with the scan. Also, MRIs are not compatible with undergarments. Also, it is a good idea not to wear jewelry and instead use a hospital gown. This will allow you to remain comfortable during your scan.
Patients can find MRI procedures scary. To reduce the level of noise produced by an MRI machine, patients might be fitted with headphones or earplugs. The intravenous line may be placed in the arm, hand, or wrist during an MRI procedure. This allows a physician to insert a contrast agent in order to obtain better images. This contrast agent does not contain iodine and is, therefore, less likely to trigger an allergic reaction. A typical MRI scan takes approximately 30 minutes.
Before you go through an MRI, be sure to fully understand the risks and benefits. Your life could be at risk if there is a pacemaker in your body or another metal implant. People with these implants should not have an MRI. Another risk that an MRI can present is the danger of a pacemaker. You should talk to your doctor about this before you undergo an MRI.
During an MRI, patients need to change into a hospital dress and take out any jewelry or other metal objects. Metal objects may interfere with the MRI scan. However, belts and undergarments are not compatible with magnetic fields. An MRI will usually require a hospital gown. An MRI can be very accurate if you are still in your position. The doctor will provide you with a gown. You can resume your regular routine once the MRI has been completed.
Talk to your physician about the risks and benefits of having an MRI done before you make any decisions. A skilled MRI technician can make you feel comfortable and will explain everything to you. Talk to your physician or radiologist if you feel claustrophobic, or are afraid of being restricted. An MRI is very painless, with most procedures taking around 30 minutes.
It is important to know what you can expect from an MRI. Typically, a patient is in the MRI machine for 30 to 50 minutes. For more complicated exams, it may take longer. Ask about the cost before you go. The MRI technician can explain the process and potential dangers. After the procedure, the doctor will give you a report. Be calm and take your time. During the scan, you are welcome to ask questions.
An MRI is expensive. It is important to verify your insurance coverage before you schedule an MRI. You also need to understand the risks. MRIs are also very painful and you should make sure that you can manage the pain. It is your health that is most important. Don’t be afraid to ask questions. There’s no reason to worry. It is simple, safe, and doesn’t cost any money. An MRI might help you to identify the root cause of claustrophobia.
An MRI machine consists of a long, metal tube that slides into the human body. An attached coil might be used to scan the specific part of your body. The MRI machine generates a strong magnetic force that takes pictures within the body. This energy is used in order to take pictures of a specific part of the body. Although there are many benefits to this technology the risks are low. The MRI machine is a convenient and safe way to diagnose certain conditions.
