What is MRI of the Body? Magnetic resonance imaging MRI is a noninvasive medical test that physicians use to diagnose medical conditions. MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures.
MRI does not use ionizing radiation x-rays. Detailed MR images allow physicians to evaluate various parts of the body and determine the presence of certain diseases. The images can then be examined on a computer monitor, transmitted electronically, printed or copied to a CD or uploaded to a digital cloud server.
What are some common uses of the procedure? MR imaging of the body is performed to evaluate: Physicians use an MR examination to help diagnose or monitor treatment for conditions such as: You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing if it is loose-fitting and has no metal fasteners.
Guidelines about eating and drinking before an MRI exam vary with the specific exam and with the imaging facility. Unless you are told otherwise, you may follow your regular daily routine and take food and medications as usual.
Some MRI examinations may require you to receive an injection of contrast material into the bloodstream. The radiologisttechnologist or a nurse may ask if you have allergies of any kind, such as an allergy to iodine or x-ray contrast material, drugs, food, or the environment, or if you have asthma.
The contrast material most commonly used for an MRI exam contains a metal called gadolinium. Gadolinium can be used in patients with iodine contrast allergy. It is far less common for a patient to have an allergy to a gadolinium-based contrast agent used for MRI than the iodine-containing contrast for CT.
However, even if it is known that the patient has an allergy to the gadolinium contrast, it may still be possible to use it after appropriate pre-medication.
Patient consent will be requested in this instance. For more information on adverse reactions to gadolinium-based contrast agents, please consult the ACR Manual on Contrast Media.
You should also let the radiologist know if you have any serious health problems, or if you have had any recent surgeries. Some conditions, such as severe kidney disease, may prevent you from being given gadolinium contrast for an MRI. If you have a history of kidney disease or liver transplant, it will be necessary to perform a blood test to determine whether the kidneys are functioning adequately.
Women should always inform their physician or technologist if there is any possibility that they are pregnant.
MRI has been used for scanning patients since the s with no reports of any ill effects on pregnant women or their unborn babies. However, because the unborn baby will be in a strong magnetic field, pregnant women should not have this exam in the first three to four months of pregnancy unless the potential benefit from the MRI exam is assumed to outweigh the potential risks.
Pregnant women should not receive injections of gadolinium contrast material except when absolutely necessary for medical treatment.
If you have claustrophobia fear of enclosed spaces or anxiety, you may want to ask your physician for a prescription for a mild sedative prior to your scheduled examination.Magnetic resonance imaging (MRI) is a noninvasive medical test that physicians use to diagnose medical conditions.

How the MRI Procedure has an Impact on Society Since the introduction of Magnetic Resonance Imaging, better known as the MRI scan, medical technology has taken a huge step forward in assisting the diagnosis of sometimes fatal diseases. MRI stands for magnetic resonance imaging, which is a noninvasive medical imaging technique used in radiology to visualize detailed internal structure and limited function of the body.
“MRI is a competent imaging machine that helps in detecting abnormalities as . A head MRI is a painless, noninvasive test that produces detailed images of your brain and brain stem. It's a useful tool for detecting a number of conditions.
What is the procedure for a head. The impact of the MRI machine has not only impacted patients and doctors in everyday life but it has sparked the domino effect of all of the other great inventions that have come after it in the medical field.
