Makary, MD. The solution can brighten certain areas of the body so that we can distinguish the structures and disease changes in your body more easily. Among the conditions that we can diagnose and track from MRI are tumors, certain inflammatory and infectious diseases, spine abnormalities, joint problems, brain injuries and structural issues in your heart.

Once you arrive, a doctor or MRI technician will review medical conditions and history in a comprehensive safety screening and address any issues at that point. They may prescribe a sedative to help the experience go more smoothly for you. This includes pacemakers, artificial heart valves, cochlear implants, joint implants and retained metal that remain in your body from previous injuries.

Some patients find the inside of the MRI scanner to be uncomfortably small and may experience claustrophobia. Imaging in an open MRI scanner may be an option for some patients, but not all MRI systems can perform all examinations, so you should discuss these options with your doctor. Your doctor may also be able to prescribe medication to make the experience easier for you.

To produce good quality images, patients must generally remain very still throughout the entire MRI procedure. Infants, small children, and other patients who are unable to lay still may need to be sedated or anesthetized for the procedure. Sedation and anesthesia carry risks not specific to the MRI procedure, such as slowed or difficult breathing, and low blood pressure.

The MR environment presents unique safety hazards for patients with implants, external devices and accessory medical devices. Examples of implanted devices include artificial joints, stents, cochlear implants, and pacemakers. An external device is a device that may touch the patient like an external insulin pump, a leg brace, or a wound dressing.

Electronic devices can be damaged and not work — by moving in the body, heating and also having abnormal electrical currents.

A pacemaker is a common device that can exclude you from having an MRI scan. Magnetic dental implants will no longer remain attached if placed in the strong magnetic fields of the MRI scanner. Magnetic strips, such as on credit cards, can also be damaged. If you are pregnant, please discuss the scan with your doctor and tell the MRI facility before your procedure. This will not necessarily stop you from having the scan.

There are no reported effects of an MRI on the unborn child, but caution is always used in pregnancy. If you are required to have an injection of gadolinium contrast medium , there is a very small risk of an allergic reaction.

Gadolinium contrast medium is generally very safe, but as with all medications, allergic reactions can occur. Minor reactions such as hives or itchy eyes can occur in approximately 1 in people. More significant reactions difficulty in breathing or collapse might occur in 1 in 10, people. The hospital radiology department or radiology practice where you are having the scan will treat you if you have an allergic reaction. There is a small risk of an allergic reaction to any of the medications that might be given during an MRI scan.

If you have a history of kidney disease, you should have a blood test before the scan to ensure that the contrast medium can be given safely. Nephrogenic systemic fibrosis is a rare, but serious complication following a gadolinium chelate injection see Gadolinium Contrast Medium MRI Contrast agents in people with very poor kidney function.

The chance of an allergic reaction to the contrast medium is very small, but please ask the MRI radiographer about the injection to obtain more information. MRI has no known long-term harmful effects, provided the safety precautions are followed.

MRI does not use ionising radiation. Avoiding the need for exposure to ionising radiation X-rays is of significant benefit to younger people and children, and MRI can also be used safely in pregnancy, if required. MRI is capable of providing your doctor with a wide range of information about your body and particular diseases or conditions you might have.

MRI can image most parts of the body in any direction to obtain maximum information and provides this information in high-quality images. These images give accurate details about certain processes or structures within the body and can also provide information as data or graphs.

The scans are then passed to a radiologist a specialist doctor , who interprets these and provides a written report to the doctor who referred you for the scan.
