What does mri look like

MRI may not always distinguish between cancer tissue and fluid, known as edema. An MRI exam typically costs more and may take more time than other imaging exams.

What does the equipment look like? How does the procedure work? How is the procedure performed? What will I experience during and after the procedure? Who interprets the results and how do I get them?

What are the benefits vs. What are the limitations of MRI of the Body? Which test, procedure or treatment is best for me? Detailed MR images allow doctors to examine the body and detect disease.

MR imaging of the body is performed to evaluate: organs of the chest and abdomen—including the heart, liver , biliary tract , kidneys , spleen , bowel, pancreas , and adrenal glands. Physicians use an MR examination to help diagnose or monitor treatment for conditions such as: tumors of the chest, abdomen or pelvis. These items include: jewelry, watches, credit cards, and hearing aids, all of which can be damaged pins, hairpins, metal zippers, and similar metallic items, which can distort MRI images removable dental work pens, pocketknives, and eyeglasses body piercings mobile phones, electronic watches, and tracking devices.

People with the following implants may not be scanned and should not enter the MRI scanning area without first being evaluated for safety: some cochlear ear implants some types of clips used for brain aneurysms some types of metal coils placed within blood vessels some older cardiac defibrillators and pacemakers vagal nerve stimulators Tell the technologist if you have medical or electronic devices in your body.

MRI exams may be done on an outpatient basis. Benefits MRI is a noninvasive imaging technique that does not involve exposure to radiation. MR images of the soft-tissue structures of the body—such as the heart, liver and many other organs— is more likely in some instances to identify and accurately characterize diseases than other imaging methods.

This detail makes MRI an invaluable tool in early diagnosis and evaluation of many focal lesions and tumors. MRI has proven valuable in diagnosing a broad range of conditions, including cancer, heart and vascular disease , and muscular and bone abnormalities. MRI can detect abnormalities that might be obscured by bone with other imaging methods. MRI allows physicians to assess the biliary system noninvasively and without contrast injection. The MRI gadolinium contrast material is less likely to cause an allergic reaction than the iodine-based contrast materials used for x-rays and CT scanning.

MRI provides a noninvasive alternative to x-ray, angiography and CT for diagnosing problems of the heart and blood vessels. Risks The MRI exam poses almost no risk to the average patient when appropriate safety guidelines are followed. If sedation is used, there is a risk of using too much. However, your vital signs will be monitored to minimize this risk.

The strong magnetic field is not harmful to you. However, it may cause implanted medical devices to malfunction or distort the images. Nephrogenic systemic fibrosis is a recognized complication related to injection of gadolinium contrast. It is exceptionally rare with the use of newer gadolinium contrast agents.

It usually occurs in patients with serious kidney disease. Your doctor will carefully assess your kidney function before considering a contrast injection. There is a very slight risk of an allergic reaction if your exam uses contrast material. Such reactions are usually mild and controlled by medication. If you have an allergic reaction, a doctor will be available for immediate assistance.

Although there are no known health effects, evidence has shown that very small amounts of gadolinium can remain in the body, particularly the brain, after multiple MRI exams. This is most likely to occur in patients receiving multiple MRI exams over their lifetime for monitoring chronic or high-risk health conditions. The contrast agent is mostly eliminated from the body through the kidneys. If you are a patient in this category, consult with your doctor about the possibility of gadolinium retention, as this effect varies from patient to patient.

A radiology technologist will perform the test in the MRI suite of the Radiology department of the hospital or outpatient imaging center. You will lie on a moveable bed with your head cradled on a headrest and your arms at your sides. An antenna device, called a coil, will be placed over or around the area of the body to be imaged.

It is specialized to produce the clearest picture of the area it is placed over. If the MRI scan will be used for surgical planning, the technologist may place small markers called fiducials on your forehead, face, or behind your ear. Fiducials look like lifesavers and assist the surgeon during image-guided surgery. Do not remove or get the fiducials wet. When you are comfortably positioned, the table will slowly move into the magnetic field.

The technologist will stay in constant contact with you. You can listen to music on a stereo system during your testing. As the exam proceeds, you will hear a muffled "thumping" sound for several minutes at a time. This is the sound of the pictures being taken. There will be no pain or discomfort associated with the sound or exam.

The exam usually takes 20 to 50 minutes. It is important that you relax and lie as still as possible. Any movement during this time will blur the picture. You may be given an injection of contrast dye gadolinium into your arm or through an IV to enhance the images.

After the test is complete, the IV will be removed and you are free to go. You may be told to drink lots of fluids to help your kidneys remove the contrast dye from your body. You lie inside the tube during the scan. The results of an MRI scan can be used to help diagnose conditions, plan treatments and assess how effective previous treatment has been.

Depending on the part of your body being scanned, you'll be moved into the scanner either head first or feet first. The MRI scanner is operated by a radiographer, who is trained in carrying out imaging investigations. They control the scanner using a computer, which is in a different room, to keep it away from the magnetic field generated by the scanner. You'll be able to talk to the radiographer through an intercom and they'll be able to see you on a television monitor throughout the scan.

At certain times during the scan, the scanner will make loud tapping noises. This is the electric current in the scanner coils being turned on and off. The ends of the scanner are always open. After your exam, the images will be reviewed by your radiologist.

He or she will send a report to the health care provider who ordered the test. Ask your health care provider any questions you have about your MRI. A cardiac MRI provides still or moving pictures of how the blood is flowing through the heart. Vivien Williams: One out of four, that's how many people will die of a heart related problem.

Doctors at Mayo Clinic are trying to improve those statistics. They're using MRI s to look inside the heart to find disease and tailor treatment to keep people healthier longer. Brian Shapiro, M. Vivien Williams: Dr. Brian Shapiro uses MRI to look for abnormalities in the heart. So, swelling of the heart is a very common thing in heart attacks, and infections, and things like that.

Shapiro how well the heart pumps, where irregular heart beats originate, the location of blood clots, artery blockages, scar tissue, or even tumors. Because MRI allows doctors to see more detail of the heart, they can make more accurate diagnoses, and therefore tailor treatment for patients. Vivien Williams: Images that tell Dr. Shapiro if a patient will recover, if there's permanent damage, and what treatments might be best. Information from inside the heart that can help Dr. Shapiro and his colleagues better help their patients.

Shapiro says while MRI can show lots of information about the heart, it does not replace other tests such as stress tests or echo cardiograms. It's another option for looking inside the heart.
