MRI (Magnetic Resonance Imaging): Frequently Asked Questions
What is an MRI?
MRI or Magnetic Resonance Imaging, is a type of powerful radiographic study that provides a clear diagnostic picture without using radiation. The MRI image gives enhanced views of the body part in question. An MRI scan of the spine, for example, provides a superior view of the discs in the back, as well as the nerves and other soft tissues. The doctor can look at the MRI films and determine whether there is a pinched nerve, a degenerative disc, a tumor, or in some cases spinal stenosis. ...

MRI or MR stands for magnetic resonance imaging. It’s a revolutionary process that produces very detailed 2- or 3-dimentional images that enable doctors to “see” through bone to the soft tissue inside the body without surgery or the radiation that is used in x-rays and CT scans. The technique has proven very valuable for the diagnosis of a broad range of pathologic conditions in all parts of the body including cancer, heart and vascular disease, stroke, and joint and musculoskeletal disorders.

MRI stands for Magnetic Resonance Imaging. An MRI offers a safe and efficient method for medical diagnosis of many conditions, without the use of harmful x-rays. In many cases, MRI can lead to early detection and treatment of disease without surgery or biopsy. It is a non-invasive method of examining the soft tissue of the body including organs, muscles and tendons.

Is this the same as MRI?
MRIs, like X-Rays, are valuable imaging tools when used properly. But they are designed to capture different things all together. While MRI does a much better job of finding and identifying tendon or ligament damage, EBT is the right technology for use in detecting Heart Disease and certain cancers. Is EBT the same technology

Is MRI harmful?
No. MRI uses no X-rays or other ionizing radiation and no known harmful side effects have been discovered to date

Is MRI safe?
Yes. The magnetic field and radio waves pose no health risks or side effects. You will be asked to complete a safety-screening questionnaire before your exam to determine if you the right candidate for MRI .

MRI does not require any invasive techniques, nor does it use any x-rays or ionizing radiation. However, because of the use of high magnetic fields, there are safety concerns if you have a pacemaker, an aneurysm clip, or if you have a history of eye injury involving metal fragments. It is important that you accurately complete the MRI Screening form , so that our staff can determine whether it is safe for you have MRI. ...

Pigments for makeup have made great developments over the past few years. We use only natural organic pigments that are MRI safe. Also because of the natural ingredients colors stay true, unlike pigments that contain iron oxide.
MRI is a completely non-invasive, painless procedure and has been demonstrated to be safe. In fact, since MRI does not use x-rays, it is even safer than a routine chest or dental x-ray study.

The strength of the magnetic field and the frequency of the radio waves have no known harmful effects. However there are some patients who cannot have an MRI test due to certain medical conditions such as pregnancy and metallic or electronically implanted devices. Not all metallic implanted are contraindicated for MRI. Consult your doctor or MRI Technologist for clarification.

Is MRI dangerous?
For the most part no, there is no danger associated with having an MRI. However, there are some implanted devices that make it impossible for some people to go through with this procedure. Our staff will carefully screen each person entering the MRI scan room to ensure everyone's safety.

MRI poses no risk to the average patient if appropriate safety guidelines are followed. Because metallic items within the body may cause discomfort or injury to you when placed in the magnetic field, it is very important that you inform your doctor or the technologist if you have: a pacemaker a metal plate, pin or other metallic implant aneyrysm clips an artifical heart valve have ever been a metal worker have an intrauterine device (IUD) have ever been wounded during military service

Is MRI painful?
Top Because MRI is a noninvasive diagnostic technique, it is not painful. The horse is given only a light sedative to minimize motion during the procedure and to ensure safety for the horse and technician. Neither the horse nor people feel any sensation when near the magnet. 4.

Is MRI noisy?
During the exam, a soft humming and thumping sound will be heard. These sounds indicate that a scan is in progress. You will be wearing headphones to block out much of the noise. If you like, bring a favorite CD to listen to or borrow one from our collection during the procedure. Ear plugs are also available.

Why an MRI?
MRI can provide very early detection of many conditions, so treatment can be more effective, accurate and rapid. The excellent quality of MRI images can also provide the best possible information if surgery is required. If there is an abnormality, MRI can show exactly where it is, its size, and what tissues are involved.

Is MRI comfortable?
There are many aspects of comfort during an MRI examination. Pain from lying in one position is sometimes a problem when exams run for 1/2 to 1 hour. Often patients are instructed to keep all or part of his or her body still for the entire procedure. If you think you may be in pain, take some medication prior to your test. Over-the-counter medications such as Aspirin or Tylenol help a great deal. Noise produced by the gradients (strong electromagnets being turned on and off) can bother some patients during the test. ...

WHAT IS AN OPEN MRI UNIT?
Open MRI refers to the physical shape of the MRI scanner. Open MRI units are usually wider and shorter than traditional MRI units. Certain open MRI scanners may even be open on all sides. Most open MRI units are of lower field strength than traditional units. The open design of the open MRI units is well suited for patients who have trouble with claustrophobia, are very young or very large.

Is there radiation form an MRI?
No, there is no radiation exposure from an MRI. The magnet produces radiofrequency waves to scan the body part.

How Safe is Open MRI?
Open MRI is quite safe in the majority of patients. Certain patients may not be able to have an MRI. These include people with implanted medical devices such as aneurysm clips in the brain, pacemakers and cochlear (inner ear) implants. Also, people with pieces of metal close to or in an important organ (such as the eye) may not be scanned.

How does MRI operate?
MR images are formed by the computer which processes signals that are emitted by body tissues. These signals are generated by using a safe magnetic field in combination with radio waves of a specific frequency. Different tissue characteristics are revealed through this process and translated into different contrast levels on the images.
