MRI - Magnetic Resonance Imaging
Magnetic Resonance Imaging - MRI
Magnetic resonance imaging (MRI) is located in the Diagnostic Imaging department on the 1st floor of the hospital. Examinations are done by appointment only with an order from a physician. Appointments can be arranged by faxing the requisition to 705-328-6197. For general inquiries regarding any examination, call 705-328-6110 and press 2.
MRI is a non-invasive diagnostic imaging technology that uses a strong magnetic field and radio frequency (RF) waves to produce images. The scanner creates a magnetic field and sends RF pulses through the body tissues. The tissue response is then measured and an image is created from this information. During the scan loud noises up to approximately 115 dB can be produced, therefore patients must wear ear plugs or a head set to protect their hearing.
MRI scans can provide information about the brain, spine, joints, organs and vessels. MRI can also illustrate differences in tissues that may not be visible with other imaging modalities. Some MR examinations require an injection of Gadolinium to visualize structures more clearly. Gadolinium has a property that makes it appear bright within a magnetic field. The Ross Memorial Hospital Diagnostic Imaging Department is equipped with an open-bore MRI, which means the inner diameter of the machine is wider than most units. This enables RMH to accommodate patients with special needs and conditions in a more comfortable setting.
The main chamber of the MRI is shorter than most models, allowing the majority of tests to be done with the patients’ head outside of the bore. This reduces anxiety and feelings of claustrophobia.
