An MRI scan is a medical imaging method that uses radio waves in order to manipulate the magnetic position of atoms inside the body. A doctor will use a powerful antenna in order to pick up radio waves, which are then sent to a computer for analysis. These results are then converted to 3-D images of any area being scanned. These images can help determine if there is any problem in the heart or brain.
Before you go under an MRI scanner, remove all metal from the body. The scan can be hampered by metals such as earrings and belts. It is also important to remove undergarments as they are not compatible with an MRI. A hospital gown is recommended. This will make sure you are comfortable during the scan.
An MRI procedure is often frightening for patients. Patients may be offered headphones or earplugs to lower the volume of an MRI machine that makes loud, thumping noises. An intravenous line can also be used to place a catheter in an arm or hand during an MRI procedure. This allows the doctor to inject a contrast agent, which will improve the images. This contrast agent isn’t iodized, so it is less likely that it will cause an allergic reaction. An MRI scan typically takes 30 minutes.
It is important that you are fully informed about the risks and advantages of an MRI before you have one. You could lose your life if the MRI is performed on someone with a pacemaker or any other metal implant. For people with these implants, an MRI scan may not be suitable. An MRI scan is also associated with a high risk of having a pacemaker. Talk to your doctor about it before getting an MRI.
During an MRI procedure, patients are required to change into a hospital gown. Although metal objects can interfere, the magnetic field will not allow for undergarments or belts to be used. An MRI usually requires a hospital dress. For the best accuracy of the images, it is important that you stay still during an MRI. Your doctor will prescribe you a gown. Once the MRI is completed, you can go back to your routine.
Discuss the risks and advantages of an MRI with your doctor before you go under. A competent MRI technician will make the experience easy for you and provide detailed explanations. You may need to talk with your physician before you undergo the test if you are feeling claustrophobic and have fear of being enclosed. An MRI can be performed with minimal pain and usually takes about 30 minutes.
Know what to expect before an MRI. Typically, a patient remains in the MRI machine between 30 and 50 min. Longer examinations are possible. Ask about the cost of your visit before you make a decision. The MRI technician should explain the process as well as any risks. After you have completed the process, your doctor will send you a detailed report. If you are concerned, take your time and carefully follow the instructions. During the scan, there are many ways to ask questions.
An MRI can cost a lot. Before you book an MRI appointment, check your insurance coverage. Make sure you fully understand the risks. MRIs can also cause severe pain so be sure to have the right insurance coverage. Asking questions is a good idea. There is no need for you to be anxious. It is easy to use, it’s comfortable, and it doesn’t cost much. An MRI may be helpful in identifying the source of claustrophobia.
An MRI machine consists of a long tube of metal that slides into the body. A small coil may be attached during the scan to the section of the body being scanned. The MRI machine creates a magnetic field that takes pictures within the body. This energy can be used to create images of specific areas of the body. While there are many advantages to this technology, the risks are minimal. The MRI machine provides a quick, safe and reliable way to diagnose problems.
