Magnetic Resonance Imaging (MRI) is a diagnostic procedure that uses a powerful magnet, radio waves, and sophisticated computers to produce a series of detailed images of the body's organs and structures.
Lourdes is proud to be the only MRI facility in the area to offer the option of high-field, high resolution imaging on two types of magnets - a traditional 1.5Tesla (T) short-bore magnet and a 1.2T open (bore-less) magnet that provides patient comfort for those who might be anxious or claustrophobic.
At 1.2T, the Hitachi Oasis High-Field Open MRI System is the most powerful whole body Open MR magnet available. It produces high-resolution images with short scan times, and its image quality is optimized by coil technology that conforms to the part of the body being scanned.
A major advantage of the new Oasis MRI System is its patient friendly design. The open or bore-less design features a 270 degree viewing angle, giving patients an unobstructed view of the room and family/loved-ones present for support. This allows claustrophobic, obese, and pediatric patients a more comfortable MRI experience with less anxiety. Soft lighting is also used to further enhance the openness of the Oasis.
The Oasis features a wide patient table with the capability of left to right motion to allow comfortable, easy positioning, and the best image quality. The table also lowers to allow easier access for wheelchair dependent patients.
A MRI exam can be scary, especially to a child. Oasis, is a truly open MRI system offering high-touch patient comfort. Open MRI provides unobstructed views for your child. It allows pediatric patients to be comforted during scanning. It allows constant parent-child contact for even the smallest patient. In most cases, the parent or guardian is able to lie beside the child and/or hold their hand, instead of just being in sight. Many times, your child can even have a favorite stuffed friend with them.
The open design may even reduce the need for sedation or anesthesia which reduces the cost of imaging and the risks to the child.
If your child requires an MRI, whether it's with the Open MRI or the traditional short-bore magnet, this video by Nationwide Children's Hospital might be a helpful tool in explaining the MRI process. Experience the MRI Process can help your child understand what to expect during an MRI, including how the machine works and the noises the machine makes.
What makes MRI different?
How does MRI differ from other diagnostic procedures, such as x-ray, computerized axial tomography (CAT or CT) scanning, or nuclear medicine studies?
In contrast to x-ray, CT scanning, and nuclear medicine, MRI provides diagnostic information without the use of radiation or radioactive substances. MRI is a non-invasive procedure, and there are no known side/after effects.
The images obtained through MRI can be used to diagnose many conditions or monitor the progress of treatment for diseases. Because MRI can see through bone and clearly define soft tissue, it can be used to make a diagnosis in some areas that x-rays cannot.
How does MRI work?
MR images are formed when signals emitted by body tissue are processed by computer software and turned into clinical images. Signals from the body are generated using a safe magnetic field in combination with radio waves of a specific frequency. The MRI signals are detected and converted to a form the computer can understand. The computer processes the MRI signals from the body to form MR images. Different tissue characteristics are revealed through this process and translated into different contrast levels on the MR images. The trained physician can then view the MR images and form a clinical diagnosis.
How do I prepare for a MRI?
No special preparation is required prior to the MRI exam. You may eat normally and go about your daily routine. Continue to take any medication prescribed by your doctor unless otherwise directed.
Before your scheduled MRI you must complete an MRI Screening Form. For your safety, you must disclose the presence of any metal objects or fragments in your body. Failing to provide proper disclosure could result in serious injury. Please download and complete the MRI Screening Form and bring it with you to your appointment. For your convenience, you can either type your information directly on to the form, or you can print the form and complete it by hand.
Because the strong magnetic field can displace or disrupt the action of implanted metallic objects, people with cardiac pacemakers cannot be scanned and should not enter the MRI area. Other implanted devices must be researched (heart valves, stents, aneurysm clips, coils, wires, etc.) and patients should bring documentation stating manufacturer and model so that the device may be ascertained safe to enter the magnetic field.
Where to go.
For information on where to go when you arrive for your appointment, visit our Where to Go page.
Patients with cardiac pacemakers, with metal slivers in their eyes, or who have specific implanted devices cannot be scanned. Any woman who is pregnant, or thinks she might be, should advise her doctor before proceeding with this exam.
MRI is performed by a highly skilled technologist and studied by a radiologist with specialized training in the field of MRI, who will then provide a written report of the findings to your physician. If you have any questions about the MRI, please call 607-798-5023.
