MRI (magnetic resonance imaging)
What is MRI?
MRI uses radio waves, a strong magnetic field and a computer to generate detailed, cross-sectional images of human anatomy. Because it produces better tissue images than x-rays can, MRI is most commonly used for brain, spine, thorax, vascular system, and musculoskeletal system (including the knee and ankle).
How should I prepare for the MRI procedure?
Because the strong magnetic field used for MRI will pull on any metal object implanted in your body, Premier staff will ask about all surgeries you have had. Some surgical implants may be a contraindication to MRI, while other surgical procedures may require a specific amount of time to pass before an MRI can be performed. Examples of surgeries that require special attention include: aneurysm clips, ear implants, brain implants, pacemakers, heart valves, stints, and intrauterine devices (IUD).
How is the procedure performed?
You will be comfortably positioned on a special table that slides into the short 4-feet bore of the MRI system opening, where the magnetic field is centrally located. The roomy 36-inch bore is open on both ends, and is well-lit in a room that provides an atmosphere that is open, "airy", and comfortable. The technologist will perform the MRI exam at the control unit in an adjoining room. You will hear tapping noises during the exam, but earplugs are provided. You will be asked to remain still during the imaging process. You will be able to communicate with the technologist through an intercom. Special needs may be accommodated with innovative and improved positioning techniques for the claustrophobic patient such as: feet first for certain procedures, aromatherapy to calm, mirrors for visual comfort, as well as oral and IV sedation.
In some cases, a contrast material may be injected into a vein in your arm to highlight internal organs and structures to make tumors, vessels and scar tissue brighter. The contrast is filtered out of your bloodstream by your kidneys and eliminated from your body in your urine within 24 hours. Side effects are rare, but information will be provided by your MRI technician.
NEW: Espree Open Bore 1.5 T MRI Scanner
By providing the greatest patient comfort and advanced imaging capabilities, the new Espree open bore 1.5 T MRI scanner at Premier Diagnostic Imaging offers patients the best of both worlds. A very wide bore, a super short magnet, and the powerful performance of 1.5 T field strength are combined to deliver an image quality not seen before in Open MRI.
The extra-large opening comfortably accommodates patients of all sizes, and is perfect for those who get anxious or claustrophobic during an MRI. Due to its short design, most exams can be done with head out and feet first.
